Incorporate the csrf_token into a dynamically generated form using JavaScript

Question

Incorporate the csrf_token into a dynamically generated form using JavaScript

After utilizing JavaScript to create a form element, I encountered an issue while trying to submit the form. The error message received was:

Forbidden (403)

CSRF verification failed. Request aborted.

The purpose behind creating this form element with JavaScript is to update the user page using AJAX. Here is the code for the created form element:


var tagform = document.createElemenet('form')
var tagbutton = document.createElemenet('button')
tagform.setAttribute('method', 'post');
tagform.setAttribute('action', '/businesshub/comment_delete/');

tagbutton.setAttribute('type', 'submit');
tagform.appendChild(tagbutton);

I am working with Django and now need to add {% csrf_token %} to my form element that was created using JavaScript. Does anyone have suggestions on how to implement this? Thank you.

Obtain CSRF Token with the following JavaScript function:

<script>
        function getCSRFToken() {
            var name = 'csrftoken=';
            var ca = document.cookie.split(';');
            for (var i = 0; i < ca.length; i++) {
                var c = ca[i];
                while (c.charAt(0) == ' ') {
                    c = c.substring(1);
                }
                if (c.indexOf(name) == 0) {
                    return c.substring(name.length, c.length);
                }
            }
            return;
        }

    </script>

Then, use Ajax like this:

$.ajax({
            url: 'your url',
            type: 'POST',
            data: formData,
            headers: {"X-CSRFToken": getCSRFToken()},

            success: function (data) {


            },

})

Make sure to include the csrf_token when sending requests to the server.

<input type="hidden" name="csrfmiddlewaretoken" value="{{ csrf_token }}">

In your scenario, it would look something like this:

var csrf =document.createElemenet('input')
csrf.setAttribute('type','hidden');
csrf.setAttribute('value','{{ csrf_token }}');
tagform.appendChild(csrf);

Here's a neat and efficient solution that I came up with. In my Django template, I utilize the {% csrf_token %} tag to generate a CSRF token.

All I have to do then is access this token using either jQuery or JavaScript.


  <script>
   var csrfToken = document.getElementsByName('csrfmiddlewaretoken')[0].value;

   var formElement = document.createElement('form');
   var buttonElement = document.createElement('button');
   var csrfTokenInput = document.createElement("input");
   csrfTokenInput.setAttribute("type", "hidden");
   csrfTokenInput.setAttribute("name", 'csrfmiddlewaretoken');
   csrfTokenInput.setAttribute("value", csrfToken);
  </script>
