Required Field Validations in JQuery Popups for MVC 4
When working with JQuery popups in MVC 4, implementing required field validations can sometimes pose challenges. Despite setting required attributes in the model and validation messages in the view, the validations may not be triggered on popups. To resolve this issue, consider the following approach:
Reparsing the Validator
The validator is initially parsed when the page loads. When dynamic content is added via popups, the validator needs to be reparsed. In your JQuery script, modify the load() function as follows:
<code class="javascript">$(this).load(actionURL, function (html) {
// Reparse the validator
var form = $('form');
form.data('validator', null);
$.validator.unobtrusive.parse(form);</code>
This code ensures that the validator is reparsed after the popup content has been loaded, allowing required field validations to work as expected.
Additional Note:
Your code does not include @Html.ValidationMessageFor(m => m.MaterialCode) to display validation error messages. It's essential to include this in your view to display validation messages when required fields are left empty.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
