在PHP表单处理时加载gif

I have a PHP form which includes a file being uploaded upon submit. As I allow pretty big files, the page can often stand there loading for ages.

Is there a way to show the user a loading animation of some sort?

    You'll need JQuery to use my code, but it's worth it:

    Put this script tag in your site <head>:

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>
    

    Put a hidden loading gif somewhere, wherever you want to see it

    <img id="loader" src="loading.gif" />
    

    Hide it on page load: $('#loader').hide();

    Then in Javascript (or even better JQuery), inside your submit function...show/hide it:

    function submit()
    {
        $('#loader').show();
        // do your upload stuff
        $('#loader').hide();    
    }
