Troubleshooting jQuery AJAX call using Generic Handler in ASP.NET

Question

What is the best method to troubleshooting a jQuery AJAX call with ASP.NET? The error function is getting called--I get the alert to popup that says \"Error\", but I don\'t

Answer 1

I tried putting in a return false to prevent a full page postback, but that didn't seem to work.

If the main problem is that clicking the button control causes a full post back instead of an asynchronous call to your handler, you can add this code anywhere inside your jQuery click event handler:

jQuery("#<%=BtnUCSSearch.ClientID %>").click(function(e) {
    // Existing code
    e.preventDefault();
})

This works rather than return false to stop the browser's normal behavior for the button click.
