jquery abort() ajax request before sending another

Question

Based on: Abort Ajax requests using jQuery... In inventory_search() - before the ajax request is made, how can I check for any current requests and abort() them before makin

Answer 1

Spinon's answer is great for aborting all ajax queries but not great for keeping track of just one.

I often find myself doing something like

var ajax_request;
function do_something()
{
    if(typeof ajax_request !== 'undefined')
        ajax_request.abort();
    ajax_request = $.ajax({
        type: 'post',
        url: '/test.php',
        data: search_data,
        success: function(data) {
            $('#catalog').html(data);
        }
    });
}
