Ajax request in progress jQuery

Question

Is there a way to check if there's ajax request in progress? Something like:

if ( $.ajax.inProgress ){ do this; } else { do that; }

Answer 1

If you are in full control of the javascript code you could increment a variable whenever you start an ajax request and decrement it when the request completes (with success, failure or timeout). This way you always know if there is a request in progress.

Answer 2

yes there is

$.ajax({
     type: 'get',
     url: 'url',
     data: {
              email: $email.val()
     },
     dataType: 'text',
     success: function(data)
     {
        if(data == '1')
        {
            $response.attr('style', '')
                     .attr('style', "color:red;")
                     .html('Email already registered please enter a different email.');
        }
        else
        {
            $response.attr('style', '')
                     .attr('style', "color:green;")
                     .html('Available');
        }
     },
     beforeSend: function(){
                $email.addClass('show_loading_in_right')
     },
     complete: function(){
                $email.removeClass('show_loading_in_right')
     }
});

the beforeSend will do the process you need to do when the ajax request has just started and complete will be called when the ajax request is complete.
