Javascript stops when loading from cache manifest in webapp

Question

My javascript code stops when the side loads from the cache manifest in the Fullscreen WebApp Mode(iPad3/iOS6).

This has the consequence that you cant do anything in the first 5 seconds. After that you can use the site as normal.

1) Why does the JavaScript Code stop? (Event Problem?)
2) How can i fix it?

Involved is:

jquery-1.8.2.min.js

EDIT:

I have experimented and found out that the JavaScript code runs normally after the event onNoUpdate and onUpdateReady. Until these two events are initiated, it passes a large time. So this is not a option.

EDIT2:

`<script type="text/javascript">

    $(document).bind('touchmove', false);


    $(document).ready(function () {
        applicationCache.onupdateready = function () {
            if (confirm("Ihre Applikation wurde aktualisiert. Soll die Darstellung neu geladen werden?")) {
                window.location.reload();
            }
        }
        applicationCache.onnoupdate = function () {

        }


        var a = document.getElementsByTagName("a");
        for (var i = 0; i < a.length; i++) {
            if (a[i].className.match("noeffect")) {
                // Here happens nothing
            }
            else {
                a[i].onclick = function () {
                    load();
                    window.location = this.getAttribute("href");
                    return false;
                };
            }
        }
    }
);`

Try inserting some logs in key spots to find out exactly where in the code the pause happens. Usually when you narrow it down enough, the answer becomes clear.

Do you have a code snippet you could post to put this in context? – RonaldBarzell Nov 09 '12 at 15:01
I add the JS Code in main post. – skull3r7 Nov 13 '12 at 13:18
