JS解析URL参数

function URL_Request(strName) {
var strHref = document.location.toString();
var intPos = strHref.indexOf("?");
var strRight = strHref.substr(intPos + 1); //==========获取到右边的参数部分
var arrTmp = strRight.split("&"); //=============以&分割成数组 for (var i = 0; i < arrTmp.length; i++) //===========循环数组
{
var dIntPos = arrTmp[i].indexOf("=");
var paraName = arrTmp[i].substr(0, dIntPos);
var paraData = arrTmp[i].substr(dIntPos + 1);
if (paraName.toUpperCase() == strName.toUpperCase()) {
return paraData;
}
}
return "";
}
