๐Ÿค” Understanding the Issue

So, you're having an issue with jQuery's .on() method and the submit event. Specifically, you have multiple form elements with the class remember, and you're using AJAX to add another form with the same class dynamically. However, the submit event on the dynamically added form doesn't seem to work with .on().

Let's dig into this problem and find a solution together! ๐Ÿง

๐Ÿ’ก Exploring Possible Solutions

It's important to note that the issue you're experiencing is not a bug. It's actually a common problem when dynamically adding elements to the DOM. The submit event bindings are not automatically applied to the newly added form because .on() only attaches event handlers to elements that exist at the time of the call.

However, fear not! There are a few simple solutions you can try to fix this problem:

Solution 1: Use Delegated Event Handling

The easiest solution is to take advantage of the power of delegated event handling in jQuery. Instead of directly binding the submit event to the form elements, you can bind it to a parent element that exists in the DOM from the beginning. This way, any dynamically added form elements within that parent will still trigger the event.

$(document).on('submit', 'form.remember', function(event) {
  // Your submit event handler logic goes here...
});

By using document as the parent element, you ensure that the event is captured even if the form is added dynamically.

Solution 2: Bind the Event After Adding the Form

Another solution is to bind the submit event to the form element right after it's added dynamically. This approach ensures that the event handler is attached to the new form specifically.

Here's an example of how you can achieve this:

// Code to add the form using AJAX
$.ajax({
  // AJAX configuration...
  success: function(response) {
    // Add the form to the DOM
    
    // Bind the submit event
    $('form.remember').on('submit', function(event) {
      // Your submit event handler logic goes here...
    });
  }
});

By adding the form and then immediately binding the submit event, you can ensure that the event handler is attached correctly.

Note: Remember to replace the success part of the AJAX configuration with the appropriate callback in your code.
