Question

I’m trying to show a simple spinner gif meanwhile a submit is being executed (it takes a bit because I have to establish some communications with providers via web services).

So, I have this:

$('#gds_form').submit(function() {
        var pass = true;
        //some validations

        if(pass == false){
            return false;
        }

        $("body").prepend('<div class="ui-widget-overlay" style="z-index: 1001;"></div>');
        $("body").prepend("<div id ='PleaseWait'><img src='/images/spinner.gif'/></div>");
        return true;
    });

the thing is, that the .gif doesn’t show any animation, it’s like it is frozen.

Why?

There’s another way to implement this (notice that I’m not using AJAX and I don’t want to)?

Thank you.

Have you tried loading the image on document ready, only having it hidden. Then display it in your function? This way, the image is already loaded and spinning.

$(document).ready(function() {
    $("body").prepend('<div id="overlay" class="ui-widget-overlay" style="z-index: 1001; display: none;"></div>');
    $("body").prepend("<div id='PleaseWait' style='display: none;'><img src='/images/spinner.gif'/></div>");
});

$('#gds_form').submit(function() {
    var pass = true;
    //some validations

    if(pass == false){
        return false;
    }
    $("#overlay, #PleaseWait").show();

    return true;
});
