Question

I try to make a jQuery.ajax call:

jQuery("#search_form").live("submit", function() {
    search_nr = jQuery("#search_input").val();
    jQuery.ajax({
        url: '/modules/mod_findarticle/process.php',
        data: "search_nr="+search_nr,
        async: true,
        'success':  function(data) {
                        alert(data);
                    },
        'error': function(jqXHR, textStatus, errorThrown) {
                  alert(jqXHR.status+",  " + jqXHR.statusText+",  "+textStatus+",  "+errorThrown);
        }
    });
});

In return i always get an alert with “0, error, error,” message. Everything’s fine with async=false.
I know that with asynchronous call the script finish work before any actual data is recieved but what can be done to avoid this?

Problem solved thanks to user mccannf :
The data was submitted twice by triggering the ‘submit’ event on the form, so the script always stopped processing data before the second call. Replacing function() in .live(...) with function(e) {e.preventDefault; ... } disables the default submit action and hence does the trick!
