Question

When one uses AJAX commands with Jquery, is it necessary to disable form action parameter in the HTML? The load URL and the action point to the same place, so is it necessary to have the action parameter?

Answer 1

You should use the event object’s preventDefault() method, which will disable any default behavior associated with the element type. This is very important for links and form submit buttons.

For example:

<!-- you have this link -->
<a id="clickme" href="test.html">Click me</a>

You can disable the loading of test.html by using preventDefault()

$('#clickme').click(function(event) {
    event.preventDefault();
    // ...
});

You can also return false in your click function for the same effect.
