使用JQuery发布请求并接收多个答案，可能吗？

Question

I know how to do a post-request with jquery and get one response, but I wonder If I can post something with AJAX and then wait for multiple responses.

The idea behind it is that I have a progressbar (which I want to animate), so I need to get the status of the execution in my background code, which I called with AJAX.

Is this possible? I checked this . But it didn't help me.

Thanks!

You can try to identify the status for ajax when this execute into your web page. Example:

<script type="text/javascript">

//in your DOM, CALL YOUR FUNCTION

    loading();

    //set an interval to stop de function if the ajax is ready and all elements are ready
    $load = {
        setInterval(function() {
            loading();
        }, 1000); //each one second this Interval was checked if the page is complety ready
    }

    function loading() {

        var x = document.readyState;
        switch (x) {
            case 'loading';
                //show, hide something or animate an toolbar before of 50%
            break;

            case 'interactive';
                 //show, hide something or animate an toolbar before of 70%
            break;

            case 'complete';
                //show, hide something
                //we clean the interval to sstop if is compete and show the toolbar in 100%
                clearInterval($load);
            break;
        }

    }

</script>
