Generate password by button in blade file - laravel

inside Laravel Blade file I'm trying to achieve a simple password generator button that inputs generated password in field
Button:
<a class="btn btn-xs btn-success" onClick=generatePass()>Generate Me</a>
<script>
function generatePass() {
var hashed_random_password = Hash::make(str_random(12));
$('#password').val(hashed_random_password);
}
</script>
The button works, tested by using console.log('button clicked');
But hashing doesn't work, I need to achieve generating a hashed password and inputs it value directly into the password form field
Any suggestion how to get that simply in blade without invloving the routes and controller files?

<a class="btn btn-xs btn-success" onClick=generatePass()>Generate Me</a>
<script>
function generatePass() {
var pass = '';
var str='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
+ 'abcdefghijklmnopqrstuvwxyz0123456789##$';
for (let i = 1; i <= 8; i++) {
var char = Math.floor(Math.random()* str.length + 1);
pass += str.charAt(char)
}
$('#password').val(pass);
}
Now at your laravel controller Hash this password.

You can't use Hash::make in javascript, that is a PHP/Laravel method.
You can use something like this to generate a random hash:
function generatePass() {
// change 12 to the length you want the hash
let randomPasswordHash = (Math.random() + 1).toString(36).substring(12);
$('#password').val(randomPasswordHash);
}

blade:
<button onclick="generateRandomPassword()">Generate Password</button>
<h2 id="password"></h2>
<script>
function generateRandomPassword() {
$.ajax({
url: '/generate-password',
success: function (data) {
$('#password').html(data);
}
});
}
</script>
route/controller:
Route::any('/generate-password', function () {
return Hash::make(Str::random(12));
});

Cloning item. The GET method is not supported for this route. Supported methods: POST

I'm trying to clone a model but when I try to I get the error in the title. This is what I'm doing
Button in vue.js
<a class="btn-link-clone action-button" :href="'survey/clone/'+scope.row.id">
<i class="fas fa-clone col-margin"></i>
</a>
Route in web.php
Route::post('survey/clone/{id}', 'SurveyController#cloneSurvey');
CloneSurvey in SurveyController
public function cloneSurvey($id)
{
$survey = Survey::findOrFail($id);
DB::beginTransaction();
$now = Carbon::now();
$activePeriod = Period::whereDate('start_date', '<=', $now)
->whereDate('end_date', '>=', $now)->get();
$clone = new Survey();
$clone->fill($survey->toArray());
$clone->name .= ' Clonado';
$clone->save();
$eval = Evaluation::findOrFail($clone->id);
if (empty($eval)) {
$eval = new Evaluation();
}
$eval->survey_id = $clone->id;
if (!empty($activePeriod)) {
$eval->init_date = $activePeriod->start_date;
$eval->end_date = $activePeriod->end_date;
}
$report = $activePeriod->end_date;
$date = strtotime($report);
$date = strtotime('+ 1 week', $date);
$eval->report_date = $date;
$eval->save();
$questions = $survey->surveyQuestions()->get()->pluck('survey_question_id')->toArray();
if (count($questions) > 0) {
$clone->surveyQuestions()->sync($questions);
}
DB::commit();
return back();
}
What is making this happen?
I've also tried this
button in vue.js
<div class="btn-link-clone action-button"
#click="clone(scope.row)">
<i class="fas fa-clone col-margin"></i>
</div>
method in vue.js
clone(row) {
this.$http.post('survey/clone/' + row.id)
.then(
() => {
this.surveys = this.$page.surveys;
},
(res) => {}
)
},
with the route the same and I get a 419 (unknown status)
You need your Route to use the get method rather than the post method. Like so:
Route::get('survey/clone/{id}', 'SurveyController#cloneSurvey');
When a user clicks on a link, that is almost always a GET request.
EDIT:
Based on the comments, I agree that changes should not be done via a get request anyway. This example should be a POST request.
Your Vue component:
<template>
...
<form>
<button
class="btn-link-clone action-button"
#click.prevent="submit(scope.row.id)"
>
<i class="fas fa-clone col-margin"></i>
</button>
</form>
...
</template>
<script>
export default {
...
methods: {
submit (id) {
// use whatever http request library you choose to execute POST HTTP request.
}
}
...
</script>
Alternatively, you could use #submit.prevent on the form tag instead of the #click.prevent on the button.
Then, as long as scope.row.id was defined on the frontend, you can use:
Route::post('survey/clone/{id}', 'SurveyController#cloneSurvey');
The GET method is not supported for this route. Supported methods: POST
You are making a GET request to a Route that only supports the POST method.
Either your vue app is making a ajax request to your server with missing headers or form incorrect form action.
You may also be passing something like a GET parameter as part of your request
i.e. http://my-app/api/example?var1=asdasdasdas

Laravel Ajax cannot update database when click on a link

I have an audio file on public folder like this-
#foreach ($songs as $song)
<a href="{{asset('/audio/' . $song->song)}}" download="" >
<button type="button" class="download" style="margin-bottom: 15px;">
<i class="glyphicon glyphicon-download">Download</i>
</button>
</a>
#endforeach
So, when i click that button it downloads the song. In my database, in "song" table there is column for song and another one for download_count which is set to default(0). I try to update download_count when i click on the link by ajax. My ajax:
$(function() {
$('.download').click(function(){
$.ajax({
url: "/update_download_count",
type:"POST",
data: {
song_id:$(this).attr('data-id')
}
});
});
});
My Route:
Route::post('/update_download_count', 'PagesController#updateDownloadCount');
Controller:
public function updateDownloadCount(){
$song_id = $_POST['song_id'];
$song->download += 1;
$song->save();
}
But, i cannot update my database however i click on the link. it still set to 0 in download_count column. Plz help, what's the wrong?
You don't actually select the song.
public function updateDownloadCount(Request $request) {
$song = Song::find($request->input("song_id"));
$song->download += 1;
$song->save();
}
Please declare object for your song modal.
public function updateDownloadCount() {
$song = Song::findOrFail($_POST['song_id']);
$song->download += 1;
$song->save();
}
public function updateDownloadCount(Request $request){
\DB::table('songs')->where('songs_id', $request->input("song_id"))->increment('download');
}
Instead of
$song->download += 1;
Try:
Song::find($request->input("song_id"))->increment('download');
I think that should work

codeigniter Click button to call a view

I am having a view with 2 buttons in my codeigniter view:
<div class="btn-main col-md-3 col-md-offset-3">
<button id="simu-mono" type="button" class="btn btn-default">SIMULATION MONO SITE</button>
</div>
<div class="btn-main col-md-3">
<button id="simu-multi" type="button" class="btn btn-default">SIMULATION MULTI SITE</button>
</div>
I would like to call another a controller to launch then a view when the button is clicked
I tried out to call the controller simu_mono by javascript, putted on /controller/simu_mono.php but doesn' t work
$(document).ready(function(){
$("#simu-mono").click(function(){
type:'GET',
url:'simu_mono'
});
$("#simu-multi").click(function(){
});
});
simu_mono.php:
<?php
class simu_mono extends CI_Controller {
public function index()
{
$this->load->view('simu_mono');
echo 'Hello World!';
}
}
?>
Thanks for your helps
Cheers
Please, if u want to redirect only use following code:
$(document).ready(function(){
$("#simu-mono").click(function(){
window.location = base_url + "/simu_mono";
});
$("#simu-multi").click(function(){
window.location = base_url + "/simu_multi";
});
});
Note that you might need base_url, use this snippet to load base_url in JavaScript variable
<script>
base_url = <?= base_url()?>
</script>
put code above in some kind of view that is loaded always (before any other JavaScript code is executed)
Additional step would be to set up routes that take care of ugly underscore symbol (_)
something like:
routes.php
$route['simu-mono'] = "simu_mono";
$route['simu-multi'] = "simu_multi";
this way you go to your page and controller following way: yourserver.ufo/simu-mono and yourserver.ufo/simu-multi
You're not doing any class of AJAX call within your javascript. I assume you're using jQuery, so, your call should be something like:
$("#simu-mono").click(function(){
$.ajax({
url: "http://your-url.com/controller/method",
type: 'post', // <- Or get option, whatever you prefer
dataType: 'json', // <- This is important to manage the answer in the success function
//data: { param1: "value1", param2: "value2"}, <- You could add here any POST params you wanted
success: function(data){
if (data.view) {
$('#here_view').html(data.view); // <- '#here_view' would be the id of the container
}
if (data.error){
console.log(data.error);
}
}
});
});
This will call your method, where you will have to indicate you want to pass the view:
<?php
class simu_mono extends CI_Controller {
public function index()
{
$return = array(
'view' => $this->load->view('simu_mono')
);
echo json_encode( $return );
}
}
?>
json_encode will allow you easily pass vars and data from PHP to your javascript, and manage them in the client view. As you see in the javascript, I added data.error, this is just in case you'll have more logic, maybe change the view you're sending, send an error if you sent data and want to control them, etc.
Of course, in your javascript you could take the url from the clicked button, and in data.view parat of the success function, you may print in the screen a modal, send the view to a container, whatever you wanted, XD

Passing mutiple arguments with AJAX. Values come from DIV

I am trying to pass two arguments thought ajax. The variables I am pulling from are in a div and are done on the fly. I can easily pass the date_time but I need to be able to pass a variable "id" also. The date is in an array that is being loaded and changes. The ID does not change for this page.
This is the javascript. Below that will be my div. All attempts to append this have failed. Any ideas?
<div class='letter' width=600 date_time=\"$date_time\" id=\"$id\">
....doing stuff here.....
</div>
function OnScrollLetters () { var div = document.getElementById ("userLetter");
var info = document.getElementById ("info");
if(div.scrollTop == (div.scrollHeight - div.clientHeight))
{
$('div#loadMoreComments').show();
$.ajax({
url: "get_letters_for_profile_scroll.php?lastComment="+ $(".letter:last").attr('date_time'),
success: function(html) {
if(html){
$("#userLetter").append(html);
$('div#loadMoreComments').hide();
}else{
$('div#loadMoreComments').replaceWith("<center><h1 style='color:red'>End of Letters</h1></center>");
}
}
});
}
}
This is my div.
<div class='letter' width=600 date_time=\"$date_time\" id=\"$id\">
....doing stuff here.....
</div>
Try place a "=" between parameter name and value
..."&id="+$(".letter:last").attr('id')

How do I show multiple recaptchas on a single page?

I have 2 forms on a single page. One of the forms has a Recaptcha displaying all the time. The other should display a Recaptcha only after a certain event such as maxing out login attempts. So there are times when I would need 2 Recaptchas to appear on the same page. Is this possible? I know I could probably use a single one for both, but the way I have the layout, I would much prefer to have 2. Thanks.
Update: well I guess it may not be possible. Can anybody recommend another capture library to use side by side with reCaptcha? I really want to be able to have 2 captchas on the same page.
Update 2: What if I put each form in an iframe? Would this be an acceptable solution?
With the current version of Recaptcha (reCAPTCHA API version 2.0), you can have multiple Recaptchas on one page.
There is no need to clone the Recaptcha nor try to workaround the problem. You just have to put multiple <div> elements for the Recaptchas and render the Recaptchas inside them explicitly.
This is easy with the Google Recaptcha API. Here is the example HTML code:
<form>
<h1>Form 1</h1>
<div><input type="text" name="field1" placeholder="field1"></div>
<div><input type="text" name="field2" placeholder="field2"></div>
<div id="RecaptchaField1"></div>
<div><input type="submit"></div>
</form>
<form>
<h1>Form 2</h1>
<div><input type="text" name="field3" placeholder="field3"></div>
<div><input type="text" name="field4" placeholder="field4"></div>
<div id="RecaptchaField2"></div>
<div><input type="submit"></div>
</form>
In your Javascript code, you have to define a callback function for Recaptcha:
<script type="text/javascript">
var CaptchaCallback = function() {
grecaptcha.render('RecaptchaField1', {'sitekey' : '6Lc_your_site_key'});
grecaptcha.render('RecaptchaField2', {'sitekey' : '6Lc_your_site_key'});
};
</script>
After this, your Recaptcha script URL should look like this:
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
Or instead of giving IDs to your Recaptcha fields, you can give a class name and loop these elements with your class selector and call .render().
Simple and straightforward:
Create your Recaptcha fields normally with this:
<div class="g-recaptcha" data-sitekey="YOUR_KEY_HERE"></div>
Load the script with this:
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
Now call this to iterate over the fields and create the Recaptchas:
<script type="text/javascript">
var CaptchaCallback = function() {
jQuery('.g-recaptcha').each(function(index, el) {
grecaptcha.render(el, {
'sitekey' : jQuery(el).attr('data-sitekey')
,'theme' : jQuery(el).attr('data-theme')
,'size' : jQuery(el).attr('data-size')
,'tabindex' : jQuery(el).attr('data-tabindex')
,'callback' : jQuery(el).attr('data-callback')
,'expired-callback' : jQuery(el).attr('data-expired-callback')
,'error-callback' : jQuery(el).attr('data-error-callback')
});
});
};
</script>
This answer is an extension to #raphadko's answer.
If you need to extract manually the captcha code (like in ajax requests) you have to call:
grecaptcha.getResponse(widget_id)
But how can you retrieve the widget id parameter?
I use this definition of CaptchaCallback to store the widget id of each g-recaptcha box (as an HTML data attribute):
var CaptchaCallback = function() {
jQuery('.g-recaptcha').each(function(index, el) {
var widgetId = grecaptcha.render(el, {'sitekey' : 'your code'});
jQuery(this).attr('data-widget-id', widgetId);
});
};
Then I can call:
grecaptcha.getResponse(jQuery('#your_recaptcha_box_id').attr('data-widget-id'));
to extract the code.
A similar question was asked about doing this on an ASP page (link) and the consensus over there was that it was not possible to do with recaptcha. It seems that multiple forms on a single page must share the captcha, unless you're willing to use a different captcha. If you are not locked into recaptcha a good library to take a look at is the Zend Frameworks Zend_Captcha component (link). It contains a few
This is easily accomplished with jQuery's clone() function.
So you must create two wrapper divs for the recaptcha. My first form's recaptcha div:
<div id="myrecap">
<?php
require_once('recaptchalib.php');
$publickey = "XXXXXXXXXXX-XXXXXXXXXXX";
echo recaptcha_get_html($publickey);
?>
</div>
The second form's div is empty (different ID). So mine is just:
<div id="myraterecap"></div>
Then the javascript is quite simple:
$(document).ready(function() {
// Duplicate our reCapcha
$('#myraterecap').html($('#myrecap').clone(true,true));
});
Probably don't need the second parameter with a true value in clone(), but doesn't hurt to have it... The only issue with this method is if you are submitting your form via ajax, the problem is that you have two elements that have the same name and you must me a bit more clever with the way you capture that correct element's values (the two ids for reCaptcha elements are #recaptcha_response_field and #recaptcha_challenge_field just in case someone needs them)
I know this question is old but in case if anyone will look for it in the future. It is possible to have two captcha's on one page. Pink to documentation is here: https://developers.google.com/recaptcha/docs/display
Example below is just a copy form doc and you dont have to specify different layouts.
<script type="text/javascript">
var verifyCallback = function(response) {
alert(response);
};
var widgetId1;
var widgetId2;
var onloadCallback = function() {
// Renders the HTML element with id 'example1' as a reCAPTCHA widget.
// The id of the reCAPTCHA widget is assigned to 'widgetId1'.
widgetId1 = grecaptcha.render('example1', {
'sitekey' : 'your_site_key',
'theme' : 'light'
});
widgetId2 = grecaptcha.render(document.getElementById('example2'), {
'sitekey' : 'your_site_key'
});
grecaptcha.render('example3', {
'sitekey' : 'your_site_key',
'callback' : verifyCallback,
'theme' : 'dark'
});
};
</script>
The grecaptcha.getResponse() method accepts an optional "widget_id" parameter, and defaults to the first widget created if unspecified. A widget_id is returned from the grecaptcha.render() method for each widget created, it is not related to the attribute id of the reCAPTCHA container!!
Each reCAPTCHA has its own response data.
You have to give the reCAPTCHA div an ID and pass it to the getResponse method:
e.g.
<div id="reCaptchaLogin"
class="g-recaptcha required-entry"
data-sitekey="<?php echo $this->helper('recaptcha')->getKey(); ?>"
data-theme="<?php echo($this->helper('recaptcha')->getTheme()); ?>"
style="transform:scale(0.82);-webkit-transform:scale(0.82);transform-origin:0 0;-webkit-transform-origin:0 0;">
</div>
<script type="text/javascript">
var CaptchaCallback = function() {
jQuery('.g-recaptcha').each(function(index, el) {
grecaptcha.render(el, {
'sitekey' : jQuery(el).attr('data-sitekey')
,'theme' : jQuery(el).attr('data-theme')
,'size' : jQuery(el).attr('data-size')
,'tabindex' : jQuery(el).attr('data-tabindex')
,'callback' : jQuery(el).attr('data-callback')
,'expired-callback' : jQuery(el).attr('data-expired-callback')
,'error-callback' : jQuery(el).attr('data-error-callback')
});
});
};
</script>
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
Access response:
var reCaptchaResponse = grecaptcha.getResponse(0);
or
var reCaptchaResponse = grecaptcha.getResponse(1);
I have contact form in footer that always displays and also some pages, like Create Account, can have captcha too, so it's dynamically and I'm using next way with jQuery:
html:
<div class="g-recaptcha" id="g-recaptcha"></div>
<div class="g-recaptcha" id="g-recaptcha-footer"></div>
javascript
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit&hl=en"></script>
<script type="text/javascript">
var CaptchaCallback = function(){
$('.g-recaptcha').each(function(){
grecaptcha.render(this,{'sitekey' : 'your_site_key'});
})
};
</script>
This is a JQuery-free version of the answer provided by raphadko and noun.
1) Create your recaptcha fields normally with this:
<div class="g-recaptcha"></div>
2) Load the script with this:
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
3) Now call this to iterate over the fields and create the recaptchas:
var CaptchaCallback = function() {
var captchas = document.getElementsByClassName("g-recaptcha");
for(var i = 0; i < captchas.length; i++) {
grecaptcha.render(captchas[i], {'sitekey' : 'YOUR_KEY_HERE'});
}
};
Looking at the source code of the page I took the reCaptcha part and changed the code a bit. Here's the code:
HTML:
<div class="tabs">
<ul class="product-tabs">
<li id="product_tabs_new" class="active">Detailed Description</li>
<li id="product_tabs_what">Request Information</li>
<li id="product_tabs_wha">Make Offer</li>
</ul>
</div>
<div class="tab_content">
<li class="wide">
<div id="product_tabs_new_contents">
<?php $_description = $this->getProduct()->getDescription(); ?>
<?php if ($_description): ?>
<div class="std">
<h2><?php echo $this->__('Details') ?></h2>
<?php echo $this->helper('catalog/output')->productAttribute($this->getProduct(), $_description, 'description') ?>
</div>
<?php endif; ?>
</div>
</li>
<li class="wide">
<label for="recaptcha">Captcha</label>
<div id="more_info_recaptcha_box" class="input-box more_info_recaptcha_box"></div>
</li>
<li class="wide">
<label for="recaptcha">Captcha</label>
<div id="make_offer_recaptcha_box" class="input-box make_offer_recaptcha_box"></div>
</li>
</div>
jQuery:
<script type="text/javascript" src="http://www.google.com/recaptcha/api/js/recaptcha_ajax.js"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
var recapExist = false;
// Create our reCaptcha as needed
jQuery('#product_tabs_what').click(function() {
if(recapExist == false) {
Recaptcha.create("<?php echo $publickey; ?>", "more_info_recaptcha_box");
recapExist = "make_offer_recaptcha_box";
} else if(recapExist == 'more_info_recaptcha_box') {
Recaptcha.destroy(); // Don't really need this, but it's the proper way
Recaptcha.create("<?php echo $publickey; ?>", "more_info_recaptcha_box");
recapExist = "make_offer_recaptcha_box";
}
});
jQuery('#product_tabs_wha').click(function() {
if(recapExist == false) {
Recaptcha.create("<?php echo $publickey; ?>", "make_offer_recaptcha_box");
recapExist = "more_info_recaptcha_box";
} else if(recapExist == 'make_offer_recaptcha_box') {
Recaptcha.destroy(); // Don't really need this, but it's the proper way (I think :)
Recaptcha.create("<?php echo $publickey; ?>", "make_offer_recaptcha_box");
recapExist = "more_info_recaptcha_box";
}
});
});
</script>
I am using here simple javascript tab functionality. So, didn't included that code.
When user would click on "Request Information" (#product_tabs_what) then JS will check if recapExist is false or has some value. If it has a value then this will call Recaptcha.destroy(); to destroy the old loaded reCaptcha and will recreate it for this tab. Otherwise this will just create a reCaptcha and will place into the #more_info_recaptcha_box div. Same as for "Make Offer" #product_tabs_wha tab.
var ReCaptchaCallback = function() {
$('.g-recaptcha').each(function(){
var el = $(this);
grecaptcha.render(el.get(0), {'sitekey' : el.data("sitekey")});
});
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://www.google.com/recaptcha/api.js?onload=ReCaptchaCallback&render=explicit" async defer></script>
ReCaptcha 1
<div class="g-recaptcha" data-sitekey="6Lc8WQcUAAAAABQKSITdXbc6p9HISCQhZIJwm2Zw"></div>
ReCaptcha 2
<div class="g-recaptcha" data-sitekey="6Lc8WQcUAAAAABQKSITdXbc6p9HISCQhZIJwm2Zw"></div>
ReCaptcha 3
<div class="g-recaptcha" data-sitekey="6Lc8WQcUAAAAABQKSITdXbc6p9HISCQhZIJwm2Zw"></div>
To add a bit to raphadko's answer: since you have multiple captchas (on one page), you can't use the (universal) g-recaptcha-response POST parameter (because it holds only one captcha's response). Instead, you should use grecaptcha.getResponse(opt_widget_id) call for each captcha. Here's my code (provided each captcha is inside its form):
HTML:
<form ... />
<div id="RecaptchaField1"></div>
<div class="field">
<input type="hidden" name="grecaptcha" id="grecaptcha" />
</div>
</form>
and
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
JavaScript:
var CaptchaCallback = function(){
var widgetId;
$('[id^=RecaptchaField]').each(function(index, el) {
widgetId = grecaptcha.render(el.id, {'sitekey' : 'your_site_key'});
$(el).closest("form").submit(function( event ) {
this.grecaptcha.value = "{\"" + index + "\" => \"" + grecaptcha.getResponse(widgetId) + "\"}"
});
});
};
Notice that I apply the event delegation (see refresh DOM after append element ) to all the dynamically modified elements. This binds every individual captha's response to its form submit event.
A good option is to generate a recaptcha input for each form on the fly (I've done it with two but you could probably do three or more forms). I'm using jQuery, jQuery validation, and jQuery form plugin to post the form via AJAX, along with the Recaptcha AJAX API -
https://developers.google.com/recaptcha/docs/display#recaptcha_methods
When the user submits one of the forms:
intercept the submission - I used jQuery Form Plugin's beforeSubmit property
destroy any existing recaptcha inputs on the page - I used jQuery's $.empty() method and Recaptcha.destroy()
call Recaptcha.create() to create a recaptcha field for the specific form
return false.
Then, they can fill out the recaptcha and re-submit the form. If they decide to submit a different form instead, well, your code checks for existing recaptchas so you'll only have one recaptcha on the page at a time.
Here's a solution that builds off many of the excellent answers. This option is jQuery free, and dynamic, not requiring you to specifically target elements by id.
1) Add your reCAPTCHA markup as you normally would:
<div class="g-recaptcha" data-sitekey="YOUR_KEY_HERE"></div>
2) Add the following into the document. It will work in any browser that supports the querySelectorAll API
<script src="https://www.google.com/recaptcha/api.js?onload=renderRecaptchas&render=explicit" async defer></script>
<script>
window.renderRecaptchas = function() {
var recaptchas = document.querySelectorAll('.g-recaptcha');
for (var i = 0; i < recaptchas.length; i++) {
grecaptcha.render(recaptchas[i], {
sitekey: recaptchas[i].getAttribute('data-sitekey')
});
}
}

It is possible, just overwrite the Recaptcha Ajax callbacks. Working jsfiddle: http://jsfiddle.net/Vanit/Qu6kn/
You don't even need a proxy div because with the overwrites the DOM code won't execute. Call Recaptcha.reload() whenever you want to trigger the callbacks again.
function doSomething(challenge){
$(':input[name=recaptcha_challenge_field]').val(challenge);
$('img.recaptcha').attr('src', '//www.google.com/recaptcha/api/image?c='+challenge);
}
//Called on Recaptcha.reload()
Recaptcha.finish_reload = function(challenge,b,c){
doSomething(challenge);
}
//Called on page load
Recaptcha.challenge_callback = function(){
doSomething(RecaptchaState.challenge)
}
Recaptcha.create("YOUR_PUBLIC_KEY");
Here is a nice guide for doing exactly that:
http://mycodde.blogspot.com.ar/2014/12/multiple-recaptcha-demo-same-page.html
Basically you add some parameters to the api call and manually render each recaptcha:
<script src="https://www.google.com/recaptcha/api.js?onload=myCallBack&render=explicit" async defer></script>
<script>
var recaptcha1;
var recaptcha2;
var myCallBack = function() {
//Render the recaptcha1 on the element with ID "recaptcha1"
recaptcha1 = grecaptcha.render('recaptcha1', {
'sitekey' : '6Lc_0f4SAAAAAF9ZA', //Replace this with your Site key
'theme' : 'light'
});
//Render the recaptcha2 on the element with ID "recaptcha2"
recaptcha2 = grecaptcha.render('recaptcha2', {
'sitekey' : '6Lc_0f4SAAAAAF9ZA', //Replace this with your Site key
'theme' : 'dark'
});
};
</script>
PS: The "grecaptcha.render" method receives an ID
I would use invisible recaptcha. Then on your button use a tag like " formname='yourformname' " to specify which form is to be submitted and hide a submit form input.
The advantage of this is it allows for you to keep the html5 form validation intact, one recaptcha, but multiple button interfaces. Just capture the "captcha" input value for the token key generated by recaptcha.
<script src="https://www.google.com/recaptcha/api.js" async defer ></script>
<div class="g-recaptcha" data-sitekey="yours" data-callback="onSubmit" data-size="invisible"></div>
<script>
var formanme = ''
$('button').on('click', function () { formname = '#'+$(this).attr('formname');
if ( $(formname)[0].checkValidity() == true) { grecaptcha.execute(); }
else { $(formname).find('input[type="submit"]').click() }
});
var onSubmit = function(token) {
$(formname).append("<input type='hidden' name='captcha' value='"+token+"' />");
$(formname).find('input[type="submit"]').click()
};
</script>
I find this FAR simpler and easier to manage.
