    Run javascript from url put in web browser bar?

    Hi
    I am looking for a way to call a javascript from the url bar in the browser.
    I have looked around on google a while but only found ways to make "ahref" run javascript. How do you run it from the browser bar?
    Thanks in advance!

    I am not sure what in the world you mean.

    You want to make it a bookmarklet?

    You want to just run code you paste in?
    Code:
     javascript:var a = "hi"; alert(a); void(0);

    That is not possible, imagine what hackers could do if they could do that.

    Well I have a similar solution when I want to load in different iframe's on a page. Is it possible to do this with div's instead?

    aside:
    we don't need void(0).
    i figured out a trick by re-reading the ecma spec.

    simplify your bookmarklets and javascript: links by using an extra semi to create an empty statement; essentially the same thing as void(0)...

    Code:
    javascript:var a = "hi"; alert(a);;
    double tested with IE8, FF3.6, O10, C4, S4.
