javascript中获取地址url参数

function GetQueryString(name)
{
var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if (r!=null) return unescape(r[2]); return null;
}

alert(GetQueryString("参数名1"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));

// 获取地址栏的参数数组
         function getUrlParams() {
             var search = window.location.search;
             // 写入数据字典
             var tmparray = search.substr(1, search.length).split("&");
             var paramsArray = new Array;
             if (tmparray != null) {
                 for (var i = 0; i < tmparray.length; i++) {
                     var reg = /[=|^==]/;    // 用=进行拆分，但不包括==
                     var set1 = tmparray[i].replace(reg, '&');
                     var tmpStr2 = set1.split('&');
                     var array = new Array;
                     array[tmpStr2[0]] = tmpStr2[1];
                     paramsArray.push(array);
                 }
             }
             // 将参数数组进行返回
             return paramsArray;
         }
 
         // 根据参数名称获取参数值
         function getParamValue(name) {
             var paramsArray = getUrlParams();
             if (paramsArray != null) {
                 for (var i = 0; i < paramsArray.length; i++) {
                     for (var j in paramsArray[i]) {
                         if (j == name) {
