reCAPTCHA : Grey out Submit button until backend interaction is finished - recaptcha

I've integrated reCAPTCHA and it is working fine, except for when the users are too quick to click the Submit button right after checking the "I'm not a robot" checkbox. It takes quite some time for reCAPTCHA to register the user action via Ajax, and if they click on Submit too quickly, the g-recaptcha-response is missing, and the validation fails.
Hence my question: how to I grey out the Submit button until g-recaptcha-response value is available?
<form id="capform" action="/captchaverify" method="POST">
<div class="g-recaptcha" data-sitekey="..."></div>
<p>
<input id="capsubmit" type="submit" value="Submit">
</form>

I ended up using the data-callback attribute as described in the documentation:
<form action="/captchaverify" method="POST">
<div class="g-recaptcha" data-sitekey="..." data-callback="capenable" data-expired-callback="capdisable"></div>
<p>
<input id="capsubmit" type="submit" value="Submit">
</form>
JavaScript (mootools-based, but the general idea should be clear):
function capenable() {
$('capsubmit').set('disabled', false);
}
function capdisable() {
$('capsubmit').set('disabled', true);
}
window.addEvent('domready', function(){
capdisable();
});

Here's an example that begins with the submit button disabled, and enables it once the callback is received from reCaptcha. It also uses jquery validate to ensure the form is valid before submitting.
var UserSubmitted = {
$form: null,
recaptcha: null,
init: function () {
this.$form = $("#form").submit(this.onSubmit);
},
onSubmit: function (e) {
if ($(this).valid()) {
var response = grecaptcha.getResponse();
if (!response) {
e.preventDefault();
alert("Please verify that you're a human!");
}
}
},
setupRecaptcha: function (key) {
UserSubmitted.recaptcha = grecaptcha.render('recaptcha', {
'sitekey': key,
'callback': UserSubmitted.verifyCallback
//'theme': 'light'//,
//'type': 'image'
});
},
verifyCallback: function (response) {
if (response) {
$(".visible-unverified").addClass("hidden");
$(".hidden-unverified").removeClass("hidden");
}
}
};
I call setupRecaptcha from the page with a named function that's part of the js include.
<script>
var recaptchaLoader = function () {
UserSubmitted.setupRecaptcha("yourkey");
};
</script>
<script src="https://www.google.com/recaptcha/api.js?onload=recaptchaLoader&render=explicit" async defer></script>
You could simplify this. I use it in a multi-tenant application with different keys, and UserSubmitted is actually part of a larger library. You can't usenamespaces (UserSubmitted.somefunction) as the onload param either (to my knowledge).

Ajax submit and replace submit button with checkmark after success

First, I'm not having luck with ajax submitting at all in cakephp 1.3 environment. Once I successfully submit, I'm hoping user stays on page and submit button hidden or replaced with a checkmark. I've tried a few things... controller without $action and then .click function instead of on submit. I'm also not versed in debugging js to see where it might be wrong so any suggestions are welcome.
Maybe "update_a" is the $action within my dashboard controller
"function applications($action) {" instead?
dashboard controller
function update_a($action) {
...
switch ($action) {
case 'save':
if (!empty($this->data)) {
// update fields in database table matching model
$this->data['Model']['submitted'] = $_POST['submitted'];
$this->data['Model']['locked'] = $_POST['locked'];
if ($this->Model->save($this->data)) {
// save form fields to other models
$this->OtherModel->saveField('form_status_id',$_POST['form_status_id']);
$this->OtherModel->saveField('form_status',$_POST['form_status']);
}
}
}
break;
default:
//$this->redirect("admin/index");
$this->render("dashboard/applications");
break;
} //case
} // end function
html
<body>
<form id='update_a' action='save'>
<div class='form-group'>
<input type='hidden' class='hidden' name='locked' id='locked' value='1'>
<input type='hidden' class='hidden' name='form_status' id='form_status' value='Locked'>
<input type='hidden' class='hidden' name='form_status_id' id='form_status_id' value='3'>
<input type='hidden' class='hidden' name='submitted' id='submitted' value='<?php echo date("Y-m-d G:i:s") ?>'>
</div>
<div class='text-center'>
<input name='submit' type='button' class='btn btn-default' value='Submit Form A'>
</div>
</form>
</body>
<script>
$(document).ready(function () {
$('#update_a').on('submit', function (e) {
//$('#update_a').click(function (e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: '/dashboard/update_a',
data: $('#update_a').serialize(),
success: function () {
alert('Form A has been submitted and locked for editing');
$('#update_a').hide();
},
error : function() {
alert("Error");
}
});
return false;
});
});
</script>

Vue Component with Stripe JS v3

I am using Vue component for my checkout form.
The stripe js (v3) file was included in the header section.
The form was in Component
This component has two section. One is to get payment details from the user and another is to submit card details.
<template>
<div class="payment_form">
<div id="payment_details" v-if="showPaymentDetails">
<!-- User input goes here. Like username phone email -->
</div>
<div id="stripe-form" v-if="showStripeForm">
<form action="/charge" method="post" id="payment-form" #submit.prevent="createStripeToken()">
<div class="form-row">
<label for="card-element">
Credit or debit card
</label>
<div id="card-element">
<!-- a Stripe Element will be inserted here. -->
</div>
<!-- Used to display Element errors -->
<div id="card-errors" role="alert"></div>
</div>
<button>Submit Payment</button>
</form>
</div>
</div>
</template>
<script>
import { Validator } from 'vee-validate';
export default {
data() {
return {
stripeToken: '',
showPaymentDetails: true,
showStripeForm: true,
}
},
created() {
},
methods: {
validateForm() {
self = this;
this.$validator.validateAll().then(result => {
if (result) {
// eslint-disable-next-line
alert('From Submitted!');
console.log(this.$data);
axios.post('/data',{
name:this.name,
})
.then(function (response) {
self.showStripeForm = true;
console.log(response);
})
.catch(function (error) {
console.log(error);
});
return;
}
});
},
createStripeToken(){
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
event.preventDefault();
window.stripe.createToken(card).then(function(result) {
if (result.error) {
// Inform the user if there was an error
var errorElement = document.getElementById('card-errors');
errorElement.textContent = result.error.message;
} else {
// Send the token to your server
console.log(result.token);
}
});
});
},
initStripe(){
window.stripe = Stripe('stripe_test_key_here');
var elements = stripe.elements();
var style = {
base: {
// Add your base input styles here. For example:
fontSize: '16px',
lineHeight: '24px'
}
};
// Create an instance of the card Element
window.card = elements.create('card', {style: style});
// Add an instance of the card Element into the `card-element` <div>
window.card.mount('#card-element');
}
},
mounted() {
this.initStripe();
setTimeout(function () {
this.showStripeForm = false;
},2000);
}
}
</script>
I try to load the stripe form on page load and try to disable the element via showStripeForm.
But vue unset the loaded stripe card form from the stripe server and saved the dom to its original state.
So i can't trigger the stripe form on the axios callback.
I don't want to user stripe checkout and stripe js v1(getting input on your own form is deprecated after this version).
In mounted. Change the setTimeout callback to an arrow function, otherwise, this will point to Window instead of Vue.
mounted() {
setTimeout(() => {
this.showStripeForm = false
}, 2000)
}
Also, the way you access the DOM is not so Vue-ish. You could use ref on the DOM element you want to use in your code. For example:
<form action="/charge" method="post" ref="payment-form" #submit.prevent="createStripeToken()">
Then access it from $refs like this:
var form = this.$refs['payment-form']
/*
Same result as document.getElementById('payment-form')
but without using an id attribute.
*/

React.js how to I go about getting data from my form and posting it

I'm currently learning React.js and am having trouble using a jquery or ajax call that returns the information in my form to a post. Basically what ever info is in the form, after submit, make a post of the data in a tag.
Here is my code:
var BasicInputBox = React.createClass({
render: function() {
return (
<div>
<label>{this.props.label}</label>
<br/>
<input type="text" onChange={this.props.valChange} value={ this.props.val} />
<br/>
</div>
);
}
});
var CommentBox = React.createClass({
render: function() {
return (
<div>
<label>Have a question?</label>
<br/>
<textarea type="text" onChange={this.props.valChange} value={ this.props.val} />
<br/>
</div>
);
}
});
var SubmitButton = React.createClass({
render: function() {
return (
<div>
<button type="submit" onClick={this.props.submit}>
Submit
</button>
</div>
);
}
});
var Contact = React.createClass({
getInitialState: function() {
return {}
},
submit: function(e) {
e.preventDefault()
console.log(this.state);
this.setState({
name: "",
email: "",
comment: ""
})
},
nameChange: function(e) {
this.setState({
name: e.target.value
})
},
emailChange: function(e) {
this.setState({
email: e.target.value
})
},
commentChange: function(e) {
this.setState({
comment: e.target.value
})
},
render: function() {
return (
<form>
<BasicInputBox label="Name:" valChange={this.nameChange} val={this.state.name}/>
<BasicInputBox label="Email:" valChange={this.emailChange} val={this.state.email}/>
<CommentBox valChange={this.commentChange} val={this.state.comment}/>
<SubmitButton submit={this.submit}/>
</form>
);
}
});
React.render(
<Contact></Contact>,
document.body
);
As #BinaryMuse noted the problem here is that your submit method is not really doing any submitting. You mentioned that the way you want to do this is via AJAX, and thus you need to 1) include jQuery (or Zepto) on your page, and 2) make the ajax call. Here is one way to accomplish the second part:
1)
First, you don't really need to provide the submit method as a property to the submit button. When the submit button is clicked inside a form, it will trigger the form's onSubmit event, so you can simply attach the this.submit method there.
Also, you don't really need I don't think to create a separate component for the Submit button. That kind of granularity may not be justified here since you can accomplish the same thing with far fewer lines of code. So I'd remove your SubmitButton component and update your Contact component render function to be:
render: function(){
return (
<form onSubmit={this.submit}>
<BasicInputBox label="Name:" valChange={this.nameChange} val={this.state.name}/>
<BasicInputBox label="Email:" valChange={this.emailChange} val={this.state.email}/>
<CommentBox valChange={this.commentChange} val={this.state.comment}/>
<button type="submit">Submit</button>
</form>
);
}
2) Next you can change your submit method in this way, adding an AJAX call. Depending on the details of the server/API to which you are sending the form you may need to modify the AJAX call a bit, but what I have put here is a fairly generic form that has a good chance of working:
submit: function (e){
var self
e.preventDefault()
self = this
console.log(this.state);
var data = {
name: this.state.name,
email: this.state.email,
comment: this.state.comment
}
// Submit form via jQuery/AJAX
$.ajax({
type: 'POST',
url: '/some/url',
data: data
})
.done(function(data) {
self.clearForm()
})
.fail(function(jqXhr) {
console.log('failed to register');
});
}
Note: that I also encapsulated the code you had previously for clearing the form inside its own function, which is called if the AJAX call returns a success.
I hope this helps. I put the code in a jsFiddle where you could test it a bit: https://jsfiddle.net/69z2wepo/9888/

.on('click') with ajax content from another ajax content

Trying to get an event triggered with ajax content whose parent elements were also ajax loaded.
<div id="content"><!-- NOT ajax-loaded -->
<div id="location"> <!-- #location IS ajax-loaded -->
<div id="add_location> <!-- #add_location IS ajax-loaded from a #location event -->
<input type="text" id="add_location_city_example" />
<input type="text" id="add_location_state_example" />
<input type="submit" id="add_location_confirm" />
</div>
</div>
</div>
$(function(){
$('#content').on('click', '#add_location_confirm', function(){
console.log('debug 1');
add_location();
// will not be called
});
$('#location').on('click', '#add_location_confirm', function() {
console.log('debug 2');
// will not be called either
add_location();
});
});
If I have onclick="add_location()" and function add_location() { console.log('debug 3); } in my .js then it will obviously be called BUT I then cannot get $('#add_location_city_example').val() because none of it will be in the dom.
NOTE: using 1.9.1
I've been using this for a while, makes it much easier to handle situations like you are describing + there is only one even assignment for pretty much all clicks on the page, including elements that will appear on the page in the future:
$(document).bind('click', function (e) {
var target = $(e.target);
if (target.is('#content')) {
e.preventDefault();
// do whatever
} else if (target.is('#location')) {
e.preventDefault();
// do whatever else
}
});
or in your case it would probably be more like this:
$(document).bind('click', function (e) {
var target = $(e.target);
if (target.is('#add_location_confirm')) {
e.preventDefault();
if (target.closest('#location').length == 0) { // not yet have location injected via ajax
// do something
} else {
// location has been injected, do something else
}
});

How get the value from a link and send the form using mootools?

I have a such form with many links:
<form name="myform" action="" method="get" id="form">
<p>
My link
</p>
<p>
My link 2
</p>
<p>
My link 3
</p>
<input type="hidden" name="division" value="" />
</form>
I would like to send the form's value from the link that was clicked to php script and get the response (not reloading the page).
I'm trying to write a function that gets the value from a link:
<script type="text/javascript">
window.addEvent('domready', function() {
getValue = function(division)
{
var division;
division=$('form').getElements('a');
}
</script>
but I don't know how to write it in a right way. Next I would like to send the form:
$$('a.del').each(function(el) {
el.addEvent('click', function(e) {
new Event(e).stop();
$('form').submit();
});
});
How I should send it to get the response from a php file not reloading the page?
Instead of putting in javascript inline in the HTML, I would suggest using a delegated event instead. I would also send the form using an ajax call instead of a form submit.
<form id="form">
<a data-value="A">My link</a>
...
</form>
<script>
var formEl = document.id('form');
formEl.addEvent('click:relay(.del)', function() {
var value = this.getProperty('data-value');
new Request.JSON({
url: '/path/to/your/listener',
onSuccess: function(data) {
// ...
}
}).get({
value: value
});
});
</script>
This works for me:
<form id="form">
<a data-value="A">My link</a>
...
</form>
<script>
var links = document.id('form').getElements('a');
links.each(function(link) {
link.addEvent('click', function(e) {
e.stop();
var value = link.getProperty('data-value');
var req = new Request.HTML({
url: "/path/to/your/listener",
data: value,
onRequest: function(){
$('display').set('text', 'Search...');
},
onComplete: function() {
},
update : $('display')
}).get(
{data: value}
);
});
})
</script>
