reading the current url of a tab

Question

I need to read the browsers URL (specefic to the tab) using javascript. I tried the

var currentURL = window.location; 
alert(currentURL.href) ; 

It shows chrome://browser/content/browser.xul instead of the web address. What should I do to get the web address?

Can someone please help me out with this.

Thanks!

Answer 1

document.location.href或window.location.href必须有效！

Answer 2

Probably already got the answer to this, but simply using document.URL will get you the tab's URL.

javascript:(alert(document.URL))
