Question

So here is my code:

$(document).ready( function() {
$('#form').bind('change', function(){
    $.ajax({
    type: 'get',
    url: 'api.php',
    data: 'task=getdirs&formname='+$('#form').attr('value'),
    dataType: "text",
    success: function (html){
        $('#chdir').html(html);
        $('#chdir select').bind('change', getDirs());
        }
    });
});
function getDirs(){
}})

#form here has a <select> element. The ajax call returns a piece of html with a new <select> element.
It works nice: in the #chdir div I get a new dropdown element. But the event inside the success part fires only once. Then this event does not work anymore at all.
What can I do to make the newly created <select> element work in the same way as the first?

You are invoking the getDirs function directly on the bind method call, you should only do it if this function returns another function, but I think that’s not the case.

Change:

$('#chdir select').bind('change', getDirs());

To:

$('#chdir select').bind('change', getDirs);

Or if you are using jQuery 1.4+, you can bind the change event with the live method only once, and you will not need to re-bind the event after that:

$(document).ready(function () {
  $('#chdir select').live('change', getDirs);
});
