Question

At some point of a Javascript, I need to redirect to another page. I do it like this.

window.location.href='http://localhost:3000/m/debug';

And then, when that page finishes loaded, I need to access the window.Ext object of this new page. I have try to do the following, but it does not work.

window.onload = function(){alert(typeof window.Ext);}; // returns 'undefined'
window.location.href='http://localhost:3000/m/debug#settings';

Or

setTimeout(function(){ alert(typeof window.Ext); },5000); // is never called
window.location.href='http://localhost:3000/m/debug#settings';

Any idea ?

Once you set window.location.href the browser navigates away from the current page – no further JavaScript will be executed … not even functions set using setTimeout/setInterval

If you want to execute JavaScript on the target page you need to add update the target page with your JavaScript !
