如果您有Undercore.js或lodash，一种快速而肮脏的方法是：

_.object(window.location.search.slice(1).split('&').map(function (val) { return val.split('='); }));

Node.js的源代码中有一个健壮的实现https://github.com/joyent/node/blob/master/lib/querystring.js

TJ的qs也执行嵌套参数解析https://github.com/visionmedia/node-querystring

function GetQueryStringParams(sParam)
{
    var sPageURL = window.location.search.substring(1);
    var sURLVariables = sPageURL.split('&');

    for (var i = 0; i < sURLVariables.length; i++)
    {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam)
        {
            return sParameterName[1];
        }
    }
}​

假设URL为

http://example.com/?stringtext=jquery&stringword=jquerybyexample

var tech = GetQueryStringParams('stringtext');
var blog = GetQueryStringParams('stringword');

非常轻量级的jQuery方法：

var qs = window.location.search.replace('?','').split('&'),
    request = {};
$.each(qs, function(i,v) {
    var initial, pair = v.split('=');
    if(initial = request[pair[0]]){
        if(!$.isArray(initial)) {
            request[pair[0]] = [initial]
        }
        request[pair[0]].push(pair[1]);
    } else {
        request[pair[0]] = pair[1];
    }
    return;
});
console.log(request);

例如，提醒？q

alert(request.q)

以下是我正在使用的：

/**
 * Examples:
 * getUrlParams()['myparam']    // url defaults to the current page
 * getUrlParams(url)['myparam'] // url can be just a query string
 *
 * Results of calling `getUrlParams(url)['myparam']` with various urls:
 * example.com                               (undefined)
 * example.com?                              (undefined)
 * example.com?myparam                       (empty string)
 * example.com?myparam=                      (empty string)
 * example.com?myparam=0                     (the string '0')
 * example.com?myparam=0&myparam=override    (the string 'override')

function getUrlParams (url) {
    var urlParams = {} // return value
    var queryString = getQueryString()
    if (queryString) {
        var keyValuePairs = queryString.split('&')
        for (var i = 0; i < keyValuePairs.length; i++) {
            var keyValuePair = keyValuePairs[i].split('=')
            var paramName = keyValuePair[0]
            var paramValue = keyValuePair[1] || ''
            urlParams[paramName] = decodeURIComponent(paramValue.replace(/\+/g, ' '))
        }
    }
    return urlParams // functions below
    function getQueryString () {
        var reducedUrl = url || window.location.search
        reducedUrl = reducedUrl.split('#')[0] // Discard fragment identifier.
        var queryString = reducedUrl.split('?')[1]
        if (!queryString) {
            if (reducedUrl.search('=') !== false) { // URL is a query string.
                queryString = reducedUrl
            }
        }
        return queryString
    } // getQueryString
} // getUrlParams

在最后一种情况下，返回“override”而不是“0”使其与PHP一致。在IE7中工作。

Use:

  $(document).ready(function () {
      var urlParams = {};
      (function () {
          var match,
          pl = /\+/g, // Regex for replacing addition symbol with a space
              search = /([^&=]+)=?([^&]*)/g,
              decode = function (s) {
                  return decodeURIComponent(s.replace(pl, " "));
              },
              query = window.location.search.substring(1);

          while (match = search.exec(query))
              urlParams[decode(match[1])] = decode(match[2]);
      })();
      if (urlParams["q1"] === 1) {
          return 1;
      }
