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

You might want to also find file paths on a local disk, and you might not want to include any hash or get strings in the path-

String.prototype.fileName= function(){
 var f, s= this.split(/[#\?]/, 1)[0].replace(/\\/g,'/');
 s= s.substring(s.lastIndexOf('/')+ 1);
 f=  /^(([^\.]+)(\.\w+)?)/.exec(s) || [];
 return f[1] ||  '';
}
