How do I parse a URL into hostname and path in javascript?

I’m trying to parse the url of the page. For example the current page is location.href.

So the main page of my blog, if I use alert(location.href); it will return “http开发者_如何学编程://diaryofthedead.co.cc/” in an alert box. If I use alert(location.href); on page two of my blog, it will return “http://diaryofthedead.co.cc/page/2” in an alert box. Is there any way to parse the URL to get the number at the end. Does anyone know how I could do that? Could I use wildcard or something, to do something like: location.href+”page/”+*; While * is equal to whatever follows “page/”, and then turn * into a variable?

You can use

var pagenum = location.pathname.match(/\/page\/(.*)/)[1];

It will extract anything past '/page/' in your URL;

Checkout this package jsuri

URI.js is a library for working with URLs. It can not only parse URLs, but also offers a simple fluent API (jQuery like) for modifying URLs.

Take a look at the documentation on the location object http://www.w3schools.com/jsref/obj_location.asp

You first want the "pathname" part, location.pathname
