Is the jQuery .change event not triggering when new rows are added to a table?

Currently, I am working on a project in asp.NET. The code-behind page is bound to a repeater control that populates a table on the webpage.

To maintain a clean look, I have hidden the table using CSS when it is empty. Now, my goal is to use jQuery to show the table once it has been filled by the repeater. However, I am encountering issues with this task. Below is a simplified example of what I have attempted:


$('#MyTable').change(function () {
    $('#MyTable').show();
})

It is worth noting that I am utilizing a basic HTML table rather than an asp:Table, eliminating the need for the .ClientID workaround and preventing server-side manipulation. I have also experimented with placing the .change event on the repeater control itself, but unfortunately, the table remains hidden even after new rows are added.

If anyone could offer some guidance on a potentially straightforward solution to achieve my desired outcome, I would greatly appreciate it.

Answer №1

The change event is triggered for combobox and listbox when the selected index changes. It may not be triggered when you append new rows to a table.

One workaround for this issue is to use an asp:panel or a simple div element to contain your HTML table. You can then set the visibility of this panel to true when adding new rows to the table.

Answer №2

When utilizing a basic HTML table, modifications may not be effective. Consider implementing this alternative approach:

HTML table onChange

Answer №3

If you want to detect DOM changes, one option is to use the livequery plugin available at this link.

Start by including the livequery plugin on your page and then implement the following code:

$('#MyTable tr') 
    .livequery(function(event) { 
       $('#MyTable').show();
        return false; 
    });

I hope this solution works for you.
