//获取参数 修复中文参数的获取 

 1 function GetRequest() {
 2     var url = location.search; //获取url中"?"符后的字串
 3     var theRequest = new Object();
 4     if (url.indexOf("?") != -1) {
 5         var str = url.substr(1);
 6         strs = str.split("&");
 7         for(var i = 0; i < strs.length; i ++) {
 8             theRequest[strs[i].split("=")[0]]=decodeURIComponent(strs[i].split("=")[1]);
 9         }
10     }
11     return theRequest;
12 }

获取参数  

//获取参数  不推荐使用,获取的参数如果有中文将出现乱码
function GetRequest() {
    var url = location.search; //获取url中"?"符后的字串
    var theRequest = new Object();
    if (url.indexOf("?") != -1) {
        var str = url.substr(1);
        strs = str.split("&");
        for(var i = 0; i < strs.length; i ++) {
            theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
        }
    }
    return theRequest;
}

返回值为undefined null 检测

 function undefinedData(v){
          if(v=='undefined'||v==null){
              return ' ';
          }else{
              return v;
          }
    }
