Ajax request in progress jQuery

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

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

To abort ajax request, Use

if($.active > 0){ 
ajx.abort();//where ajx is ajax variable
}

To continue running ajax request, Use

if($.active > 0){ 
return;

}

You might like this:

$(document).ready(function() {
    var working = false;
    $("#contentLoading").ajaxSend(function(r, s) {
        $(this).show();
        $("#ready").hide();
        working = true;
    });

    $("#contentLoading").ajaxStop(function(r, s) {
        $(this).hide();
        $("#ready").show();
        working = false;
    });

    $('#form').submit(function() {
        if (working) return;
        $.post('/some/url', $(this).serialize(), function(data){
            alert(data);
        });
    });
});

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.

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.

You should basically set a variable on top of script set to false and on ajax initiate set it to true and in the success handler set it to false again as described here.
