Why Does My jQuery .reset() Method Stop Working After Expanding My Codebase?

Why Does Resetting a Form with jQuery's .reset() Method Stop Working When Codebase Grows?

In this common scenario, a user reported that their form reset functionality using jQuery's .reset() method stopped working after their codebase expanded.

HTML Structure

The HTML structure of the form is as follows:

<code class="html"><form id="configform">
  <!-- Form elements and submit/reset buttons -->
</form></code>

Initial jQuery Code and Error

The user's original jQuery code, which previously worked, was:

<code class="javascript">$('#configreset').click(function() {
  $('#configform')[0].reset();
});</code>

However, after the codebase expanded, this code no longer functioned.

Updated jQuery Code and Error

The user updated their jQuery code to the following:

<code class="javascript">$('#form_id').trigger("reset");</code>

Resolution

The issue could lie in the updated jQuery scripts included. The user was using the following scripts:

<code class="html"><script src="static/jquery-1.9.1.min.js"></script>
<script src="static/jquery-migrate-1.1.1.min.js"></script>
<script src="static/jquery.mobile-1.3.1.min.js"></script></code>

After reverting to the previous jQuery script configuration, the form reset functionality was restored.

Possible Cause:

The updated jQuery scripts may have introduced a bug or compatibility issue that affects the .reset() method's behavior. Downgrading back to the original script configuration resolves the issue.
