举例：假如有这样一个‘路径 http://localhost:8081/page/shop-02.html?type=fruits 想取到参数type的值，可以像下面一样调用
调用
$(
function(){
var type = g_getQueryString(
"type");
console.log(type);
});
获取url参数
function g_getQueryString(name) {
var reg =
new RegExp(
"(^|&)" + name +
"=([^&]*)(&|$)");
var r = window.location.search.substr(
1).match(reg);
if(r !=
null)
return unescape(r[
2]);
return null;
};
