應用場景：訪問某個html靜態頁面時需要帶上大量引數

如: http://localhost：8086/seeyon/h5/edoc/index.jsp?id=123123454&name=joke&age=16&job=worker

var url = window.search; //  ?id=123123454&name=joke&age=16&job=worker
var theRequest = new Object();
var strs = "";
if(url.indexOf("?") != -1){
 var str = url.substr(1
 
) //  id=123123454&name=joke&age=16&job=worker
 strs = str.split("&");
 for(var i=0;i<strs.length;i++){
 theRequest[strs[i].split("=")[0]] =decodeURIComponent(strs[i].split("=")[1])  //這一步相當於賦值  theRequest[id]=123123454
 }
}

方法二：
function _getQueryString(name) {
var reg = new RegExp(“(^|&)” + name + “=([^&]*)(&|$)”); //構造一個含有目標引數的正則表示式物件
var r = window.location.search.substr(1).match(reg); //匹配目標引數
if (r != null) return decodeURIComponent(r[2]);
return null; //返回引數值
}
