将URL分解为其组件 [英] Break a URL into its components

问题描述

我正在使用javascript并希望获取我拥有的URL字符串并将其分解为其组件，例如主机，路径和查询参数。

<我需要这样做才能获得一个查询参数，它本身就是一个URL，因此用原始的URL字符串编码。

我觉得就像在Javascript中应该有一个简单的方法来做到这一点。也许看起来像这样：

  var what_I_Want = url（http://www.domain.com?queryArg1=somequeryargument ）.getQueryArgumentValue（ queryArg1\" ）; 
  

解决方案

parseUri 功能将完成您​​需要的一切

另外，您可以让DOM为您的辛勤工作并访问属性在新创建的 a 对象上，用于URL的不同部分。

I'm using javascript and would like to take a URL string that I have and break it down into its components such as the host, path, and query arguments.

I need to do this in order to get to one of the query arguments, which is itself a URL and is thus encoded in the original URL string.

I feel like there should be an easy way to do this in Javascript. Perhaps something that looks like this:

var what_I_Want = url("http://www.domain.com?queryArg1=somequeryargument").getQueryArgumentValue("queryArg1");

解决方案

The parseUri function will do everything you need

Edit Alternatively you can get the DOM to do the hard work for you and access properties on a newly created a object for different parts of the URL.
