Get page url using javascript

Question

Could someone recommend a way to get page name from a url using JavaScript?

For instance if I have:

http://www.cnn.com/news/1234/news.html?a=1&b         


        

Answer 1

var url = "http://www.cnn.com/news/1234/news.html?a=1&b=2&c=3";
url = url.replace(/^.*\//, "").replace(/\?.*$/, "");

You can substitute url with window.location
