使用jQuery/Javascript获取查询字符串参数url值(querystring) [英] Get query string parameters url values with jQuery / Javascript (querystring)

问题描述

任何人都知道编写jQuery扩展来处理查询字符串参数的好方法吗?我基本上想扩展jQuery magic ($)函数，以便可以执行以下操作:

Anyone know of a good way to write a jQuery extension to handle query string parameters? I basically want to extend the jQuery magic ($) function so I can do something like this:

$('?search').val(); 

在以下URL中，谁会给我值"test":.

Which would give me the value "test" in the following URL: http://www.example.com/index.php?search=test.

我已经看到很多可以在jQuery和Javascript中实现此功能的函数，但实际上我想扩展jQuery以使其完全如上所示工作.我不是在寻找jQuery插件，而是在寻找jQuery方法的扩展.

I've seen a lot of functions that can do this in jQuery and Javascript, but I actually want to extend jQuery to work exactly as it is shown above. I'm not looking for a jQuery plugin, I'm looking for an extension to the jQuery method.

使用纯jQuery.我只是用这个，它起作用了.例如，对它进行了一些调整.

Using PURE jQuery. I just used this and it worked. Tweaked it a bit for example sake.

//URL is http://www.example.com/mypage?ref=registration&email=[e-mail]

$.urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)')
                      .exec(window.location.search);

    return (results !== null) ? results[1] || 0 : false;
}

console.log($.urlParam('ref')); //registration
console.log($.urlParam('email')); //[e-mail]

随便使用.
