Show loading gif after clicking form submit using jQuery

Better and clean example using JS only

Step 1 - Create your java script and place it in your HTML page.

<script type="text/javascript">
    function ShowLoading(e) {
        var div = document.createElement('div');
        var img = document.createElement('img');
        img.src = 'loading_bar.GIF';
        div.innerHTML = "Loading...<br />";
        div.style.cssText = 'position: fixed; top: 5%; left: 40%; z-index: 5000; width: 422px; text-align: center; background: #EDDBB0; border: 1px solid #000';
        div.appendChild(img);
        document.body.appendChild(div);
        return true;
        // These 2 lines cancel form submission, so only use if needed.
        //window.event.cancelBubble = true;
        //e.stopPropagation();
    }
</script>

Step 2 - in your form call the java script function on submit event.

<form runat="server"  onsubmit="ShowLoading()">
</form>

Soon after you submit the form, it will show you the loading image.
