$(document).ready(function () {

    // Hide the "busy" Gif at load:
    $("#fade").hide();

    // Attach click handler to the submit button:
    $('#process').click(function () {
        $('#myform').submit();
        $("#fade").css("display", "block");
        $('#fade').css({ 'width': 8000, 'height': 8000 })
                         .fadeIn(10).fadeTo('slow', 0.7);

        // Handle the form submit event, and make the Ajax request:
        $("#myform").on("submit", function (event) {
            event.preventDefault();

            // Show the "busy" Gif:
            $("#fade").show();
            var url = $(this).attr("action");
            var formData = $(this).serialize();
            $.ajax({

Try re-ordering, note I've also amended the html to make it work with IE.

HTML

<div id="fade" class="fade" style="display: none; text-align: center;    z-index: 9999999999;">
    <img src='@Url.Content("~/images/loadingg3.gif")' style="opacity: inherit; filter: inherit; top: 60%; position: fixed; left: 1%;" width="150" height="150" />
</div>

<form id="myform" action="/home/GetData" method="post">
    <input type="text" name="MyText" />
    <input type="submit" value="Submit" />
</form>

<a href="#" id="process">Process</a>

<script type="text/javascript">
    // Handle the form submit event, and make the Ajax request:
    $("#myform").on("submit", function (event) {
        event.preventDefault();

        // Show the "busy" Gif:
        $('#fade').fadeTo('slow', 0.7);

        var url = $(this).attr("action");
        var formData = $(this).serialize();
        
        $.ajax({
            url: url,
            type: "POST",
            data: formData,
            dataType: "json",
            success: function (resp) {
                // Hide the "busy" gif:
                $("#fade").hide();
                // Do something useful with the data:
                alert(resp.result);
            }
        })
    });

    $('#process').click(function () {
        $('#myform').submit();
    });
</script>

Controller

C#

public ActionResult GetData(FormCollection form)
{
    // injecting an artifical delay so the loader can be seen
    System.Threading.Thread.Sleep(3000);

    return Json(new { result = form["MyText"] });
}
