No, that is not how Javascript is meant to work in the browser. Once the browser starts opening a new document, any code that hasn't been executed yet in the old one stops running and a totally new environment is loaded.

You can experience it firsthand by first running this code in the console and waiting:

window.setTimeout(console.log, 5000, 'hi');

After 5 seconds, the message 'hi' will display. Then try this:

function test() {
    document.location.href = 'http://www.google.com';
    window.setTimeout(console.log, 5000, 'ciao');
}
test();

Gooogle will load and no message will be shown in the console. Basically, your code was aborted and had no access to the new page.
