Question

My url will look like this:

http://www.example.com/category/action

How can I get the word \"action\". This last part of the url (after the last forward slash

Answer 1

Assuming there is no trailing slash, you could get it like this:

var url = "http://www.mysite.com/category/action";
var parts = url.split("/");
alert(parts[parts.length-1]);

However, if there can be a trailing slash, you could use the following:

var url = "http://www.mysite.com/category/action/";
var parts = url.split("/");
if (parts[parts.length-1].length==0){
 alert(parts[parts.length-2]);
}else{
  alert(parts[parts.length-1]);  
}
