我使用parseUri库。它允许您完全按照您的要求进行操作：

var uri = 'www.test.com/t.html&a=1&b=3&c=m2-m3-m4-m5';
var c = uri.queryKey['c'];
// c = 'm2-m3-m4-m5'

我尽可能喜欢速记：

网址：example.com/mortgage_calc.htm？pmts=120&intr=6.8&prin=10000

香草Javascript：

for ( var vObj = {}, i=0, vArr = window.location.search.substring(1).split('&');
        i < vArr.length; v = vArr[i++].split('='), vObj[v[0]] = v[1] ){}
// vObj = {pmts: "120", intr: "6.8", prin: "10000"}

简化版，已测试

function get(name){
    var r = /[?&]([^=#]+)=([^&#]*)/g,p={},match;
    while(match = r.exec(window.location)) p[match[1]] = match[2];
    return p[name];
}

用法：

var parameter=获取['parameter']

这是一个我觉得更可读的解决方案，但它需要一个.forEach（）填充程序，用于<IE8:

var getParams = function () {
  var params = {};
  if (location.search) {
    var parts = location.search.slice(1).split('&');

    parts.forEach(function (part) {
      var pair = part.split('=');
      pair[0] = decodeURIComponent(pair[0]);
      pair[1] = decodeURIComponent(pair[1]);
      params[pair[0]] = (pair[1] !== 'undefined') ?
        pair[1] : true;
    });
  }
  return params;
}

您可以添加一个输入框，然后要求用户将值复制到其中……这非常简单：

<h1>Hey User! Can you please copy the value out of the location bar where it says like, &m=2? Thanks! And then, if you could...paste it in the box below and click the Done button?</h1>
<input type='text' id='the-url-value' />
<input type='button' value='This is the Done button. Click here after you do all that other stuff I wrote.' />

<script>
//...read the value on click

好吧，但说真的。。。我发现了这段代码，它似乎很有用：

http://www.developerdrive.com/2013/08/turning-the-querystring-into-a-json-object-using-javascript/

function queryToJSON() {
    var pairs = location.search.slice(1).split('&');

    var result = {};
    pairs.forEach(function(pair) {
        pair = pair.split('=');
        result[pair[0]] = decodeURIComponent(pair[1] || '');
    });

    return JSON.parse(JSON.stringify(result));
}

var query = queryToJSON();

一个内衬和IE11友好：

> (window.location.href).match('c=([^&]*)')[1]
> "m2-m3-m4-m5"
