I want to send data from HTML view to Django backend to process and then the backend will send an url back the to HTML view which will redirect the user to another page. It's like this:
Page 1 ----user's input data --- Ajax --- > backend --- process --- a url to page 2 --- Ajax --> page 2
The problem is that, I don't know how to send the URL back Ajax after processing user's data, so I have to redirect by using window.location.href = '/' . But I think the code is not clean this way. I wonder if there is a way to send url to Ajax's success from backend.
Here is the code n the HTML :
function doSomething(data){
$.ajax({
type: "POST",
url: URL_POST_BY_AJAX,
data: {
'data' : data,
},
success: function (response) {
window.location.href = '/';
},
error: function (data) {
alert('failed');
}
});}
Please help me. Thank you!
In your processing view:
from django.http.response import JsonResponse
def whatever_your_view_name_is(request):
(data processing...)
return JsonResponse({'url': the_url_to_page_2)
then in your JS:
(...)
success: function (response) {
window.location.href = response.url;
},
(...)

I am new to AJAX and grails so any help is appreciated. on my GSP page, on button click I am trying to retrieve a variable from the controller:
$.ajax({
url:'${createLink(controller: 'store', action: 'getNum')}',
type: 'GET',
dataType: 'json',
data: {num: num}, // the num is defined before and access properly
error: function() {
alert("error");
},
success: function(data) {
alert(data);
}
});
this is my controller function:
def getNum(){
String num = params.num
Long locnum = num as Long
int result = storeService.getNum(locnum)
String json = JsonOutput.toJson([count: result])
return json
}
I am going into the error and getting an "error" alert. I was wondering how I could utilize AJAX to get the number I need for my GSP page?
Thank you.
I would modify your JavaScript code like so:
$.ajax({
url:'store/getNum',
method: 'POST'
data: {'num': num}, // the num is defined before and access properly
error: function() {
alert("error");
},
success: function(data) {
alert(data);
}
});
And then modify your Grails controller code like so:
def getNum() {
Long locnum = = params.long('num')
int result = storeService.getNum(locnum)
return render([count: result] as JSON) // you will need to import grails.converters.JSON
}
A tip for the future is to set a breakpoint in your Grails controller method and run the application in Debug mode to ensure that the controller method is being called. If it is not being called, click on the Network tab on your internet browser's Developer Tools and then press the button on your GSP page to inspect the HTTP request being made by the AJAX call.
I'm unsure if I'm just thinking of this the wrong way of thinking or I'm just missing something.
I have a search box that does some wildcard searches in a database. I have made this an ajax request so I don't need to reload the page and I can have a little please wait icon while the data loads.
Now as there is pagination so I could do with the url parameters being added to the url, can you do this on a ajax request, ad if so how?
here is a sample code (param1) :
data : $('#form-contactSupplementaire').serialize() + "¶m1=value",
Request full ajax :
$.ajax({
method : "POST",
url : "...",
data : $("...").serialize() + "¶m1=value",
dataType: "",
success : function (json) {
// ...
console.log(json);
}, error: function () {
console.log("Error");
}
});
I'm pushing an ajax post with jquery to e method in the controller which should return a json response but I'm not getting anything, no errors but no response either. Then end goal is broader as you will see from my ajax but for now getting that response back from the controller would be stellar
The jquery ajax method:
$.ajax({
url : "/menu/sort",
type : 'POST',
data : { menu: menu, order: order },
success: function (data) {
holder.html(data);
}
});
The controller action:
return Response::json('ok');
my route:
Route::post('menu/sort', 'MenuController#sort');
i have an ajax load request working in wordpress, but i would like to load the content from another page into the container div. at the moment it just passes the url in $dataToSend as a string?
jQuery(document).ready(function(){
var $dataToSend = "my-page.php";
var $testBtn = jQuery('#text-ajax-btn');
var $holdingCtn = jQuery('#my-holding-ctn');
$testBtn.click(function(){
jQuery.ajax({
type:'POST',
url: myAjax.ajaxurl,
data:{
action:'myAjax',
dataToSend:$dataToSend,
},
success: function(data,textStatus,XMLHttpRequest){
$holdingCtn.html("");
$holdingCtn.append(data);
},
error: function(XMLHttpRequest, textStatus, errorThrown){
alert(errorThrown);
}
});
});
});
how can i pass an entire .php page through as the $dataTosend?
I do this all the time for wordpress, give me a sec to access my repository and I will show you example code.
I think problem is your my-page.php! I imagine you custom coded it. So it doesn't have necessary functions loaded.
put following code at the top of your my-page.php (this will help with 500 error you are getting)
require('../../../wp-load.php');
ajax part should look something like this:
//start ajax
$.ajax({
url: "http://localhost/wp-content/themes/theme/my-page.php",
type: "POST",
data: data,
cache: false,
success: function (data) {
console.dir(data);
}
})
If you want to load content from my-page.php file then you can load from the server side using
$data = file_get_contents('path/to/file/my-page.php'); // pass right path/url
Then, just echo the content from your function (registered ajax handler in WordPress using add_action) and in this case it should be
echo $data;
die(); // terminate the further execution
So, it should look something like
add_action( 'wp_ajax_myAjax', 'yourAjaxHandler' );
add_action( 'wp_ajax_nopriv_myAjax', 'yourAjaxHandler' );
function yourAjaxHandler(){
$data = file_get_contents('path/to/file/my-page.php');
die($data); // echo out the string and terminates execution
}
In your success callback, you can use
success: function(data){
jQuery('#my-holding-ctn').html(data);
}
Not sure if this is fully applicable, but the super easy way is just
$("#myDiv").load("myFile.php?foo=1&bar=2...");
I have the following code I am using to submit my form to a processing script. the form gets submitted but I am getting redirected to the response html from the server. I want to stay on the same page and run the callback function inside success:
the response header is sending
location:http://url-I-am-Redirected-to-and-don't-want-to-be.html
I am working with third party and have no control over the server side code I am submitting to.
$('#go').click (function () {
$.ajax ( {
type: 'POST',
data: $('#newsletter form').serialize(),
url: $('#newsletter').attr('action'),
success: function(){
$('#image_container').hide (1000,
);
}
});
}
At the end of the click block add
return false
