Call the function only after the browser is fully redirected?

<script>
function test() {
    alert("this should only be called after the browser is fully redirected?");
}
window.location = 开发者_StackOverflow社区"http://google.com";
test();
</script>

I'm about redirecting the user guys to a page and I want to do something (call a function) only after the browser is fully redirected but I can't get it to work. Is there any way for me to do so?

Nope. When the page has opened google.com, you no longer have any control over the browser window.

Once URL changes, all execution of the current page is stopped.

Not really. You'd have to put the page you were redirecting in a frame and keep the script in another frame, then watch for the content frame to get updated. But you'd also run into cross-domain issues because of the Same Origin Policy (which governs access to one document's contents [the new page] from another document [the one containing the script you're running]). So basically, you can't do this.

If you post a separate question saying what you're trying to achieve by running more code afterward, it may be that people can help you with alternative approaches.

i don't believe this would work. it's a form of XSS/injection and therefore a security risk. i don't think the W3C allowed this sort of thing because it's very dangerous. as soon as the user is loading a different page, the browser ignores the previous one.
