Parse URL with Javascript

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.
我正在尝试解析页面的 url。例如当前页面是location.href。
So the main page of my blog, if I use alert(location.href); it will return “http://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?
所以我博客的主页，如果我使用 alert(location.href); 它将在警告框中返回“ http://diaryofthedead.co.cc/”。如果我使用 alert(location.href); 在我博客的第二页，它会在警告框中返回“ http://diaryofthedead.co.cc/page/2”。有什么方法可以解析URL以获取最后的数字。有谁知道我怎么能做到这一点？我可以使用通配符或其他东西来做类似的事情：location.href+”page/”+*; 而 * 等于“page/”后面的任何内容，然后将 * 变成一个变量？

You can use
您可以使用
var pagenum = location.pathname.match(/\/page\/(.*)/)[1];
It will extract anything past '/page/' in your URL;
它将提取 URL 中“/page/”之后的任何内容；

Take a look at the documentation on the location object http://www.w3schools.com/jsref/obj_location.asp
查看有关位置对象的文档http://www.w3schools.com/jsref/obj_location.asp
You first want the "pathname" part, location.pathname
您首先需要“路径名”部分，location.pathname
