1、JavaScript 常用工具类封装

（1）获得浏览器地址所有参数

  1. // 获得浏览器地址所有参数
  2.     function getQueryString() { 
  3.         var qs = location.search.substr(1), // 获取url中"?"符后的字串
  4.             args = { }, // 保存参数数据的对象
  5.             items = qs.length ? qs.split("&") : [], // 取得每一个参数项
  6.             item = null,
  7.             len = items.length;
  8.         for(var i = 0; i < len; i++) { 
  9.             item = items[i].split("=");
  10.             var name = decodeURIComponent(item[0]),
  11.                 value = decodeURIComponent(item[1]);
  12.             if(name) { 
  13.                 args[name] = value;
  14.             }
  15.         }
  16.         return args;
  17.     }

（2）将json转为get参数

  1. // 将json转为get参数
  2.     function getParamByJson(json) { 
  3.         return Object.keys(json).map(function (key) { 
  4.             return encodeURIComponent(key) + "=" + encodeURIComponent(json[key]);
