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"}

我见过的大多数实现都错过了URL对名称和值的解码。

下面是一个通用的实用程序函数，它也可以进行正确的URL解码：

function getQueryParams(qs) {
    qs = qs.split('+').join(' ');

    var params = {},
        tokens,
        re = /[?&]?([^=]+)=([^&]*)/g;

    while (tokens = re.exec(qs)) {
        params[decodeURIComponent(tokens[1])] = decodeURIComponent(tokens[2]);
    }

    return params;
}

//var query = getQueryParams(document.location.search);
//alert(query.foo);

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;
}

您可以在location.search中获取查询字符串，然后可以分割问号后的所有内容：

var params = {};

if (location.search) {
    var parts = location.search.substring(1).split('&');

    for (var i = 0; i < parts.length; i++) {
        var nv = parts[i].split('=');
        if (!nv[0]) continue;
        params[nv[0]] = nv[1] || true;
    }
}

// Now you can get the parameters you want like so:
var abc = params.abc;

看看这个

function getURLParameters(paramName)
{
    var sURL = window.document.URL.toString();
    if (sURL.indexOf("?") > 0)
    {
        var arrParams = sURL.split("?");
        var arrURLParams = arrParams[1].split("&");
        var arrParamNames = new Array(arrURLParams.length);
        var arrParamValues = new Array(arrURLParams.length);

        var i = 0;
        for (i = 0; i<arrURLParams.length; i++)
        {
            var sParam =  arrURLParams[i].split("=");
            arrParamNames[i] = sParam[0];
            if (sParam[1] != "")
                arrParamValues[i] = unescape(sParam[1]);
            else
                arrParamValues[i] = "No Value";
        }

        for (i=0; i<arrURLParams.length; i++)
        {
            if (arrParamNames[i] == paramName)
            {
                //alert("Parameter:" + arrParamValues[i]);
                return arrParamValues[i];
            }
        }
        return "No Parameters Found";
    }
}

ECMAScript 6解决方案：

var params = window.location.search
  .substring(1)
  .split("&")
  .map(v => v.split("="))
  .reduce((map, [key, value]) => map.set(key, decodeURIComponent(value)), new Map())
