应用场景：访问某个html静态页面时需要带上大量参数
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]) //这一步相当于赋值 theRequest[id]=123123454
}
}方法二：
function _getQueryString(name) {
var reg = new RegExp(“(^|&)” + name + “=([^&]*)(&|$)”); //构造一个含有目标参数的正则表达式对象
var r = window.location.search.substr(1).match(reg); //匹配目标参数
if (r != null) return decodeURIComponent(r[2]);
return null; //返回参数值
}
