下面是String原型实现：

String.prototype.getParam = function( str ){
    str = str.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regex = new RegExp( "[\\?&]*"+str+"=([^&#]*)" );    
    var results = regex.exec( this );
    if( results == null ){
        return "";
    } else {
        return results[1];
    }
}

示例调用：

var status = str.getParam("status")

str可以是查询字符串或url

var getUrlParameters = function (name, url) {
    if (!name) {
        return undefined;
    }

    name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]');
    url = url || location.search;

    var regex = new RegExp('[\\?&#]' + name + '=?([^&#]*)', 'gi'), result, resultList = [];

    while (result = regex.exec(url)) {
        resultList.push(decodeURIComponent(result[1].replace(/\+/g, ' ')));
    }

    return resultList.length ? resultList.length === 1 ? resultList[0] : resultList : undefined;
};

从MDN：

function loadPageVar (sVar) {
  return unescape(window.location.search.replace(new RegExp("^(?:.*[&\\?]" + escape(sVar).replace(/[\.\+\*]/g, "\\$&") + "(?:\\=([^&]*))?)?.*$", "i"), "$1"));
}

alert(loadPageVar("name"));

这会奏效的。。。您需要在需要通过传递其名称来获取参数的地方调用此函数。。。

function getParameterByName(name)
{
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  alert(results[1]);
  if (results == null)
    return "";
  else
    return results[1];
}

快速、轻松、快速：

功能：

function getUrlVar() {
    var result = {};
    var location = window.location.href.split('#');
    var parts = location[0].replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        result [key] = value;
    });
    return result;
}

用法：

var varRequest = getUrlVar()["theUrlVarName"];

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;
      }
