获取地址栏参数,json遍历

1. 获取地址栏参数

 GetQueryString: function(name){     // 获取地址栏参数

            var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
            var r = window.location.search.substr(1).match(reg);
            if(r!=null)return  decodeURIComponent(r[2]); return null;
        }

2. 如果有一个结构比较深的json表，需要通过属性去遍历他的层次

function deepJson(obj, page) {
            var result = {};
            ; (function walkTree(obj, page) {
                for (key in obj) {
                    if (key == page) {
                        result = obj[key];
                        break;
                    } else if (obj[key].subMenu) {
                        walkTree(obj[key].subMenu, page);
                    }
                }
            })(obj, page);
            return result;
        }

//根据路由确定面包屑的菜单
       function  deepJsonMenu(page) {

            var menu = page.split('/'),
