常用功能的封装

function h5App(){

  this.setItem = function(key,val){
    var str = JSON.stringify(val)
    localStorage.setItem(key,str);
  }
  this.getItem = function(key){
    if (key == '' || key == undefined) {
    key = "produstList";
  }
  this.clear = function(){
    localStorage.clear();
  }

  //多个参数

  this.get_url = function (key){
    // 获取参数
    var url = window.location.search;
    // 正则筛选地址栏
    var reg = new RegExp("(^|&)"+ key +"=([^&]*)(&|$)");
    // 匹配目标参数
    var result = url.substr(1).match(reg);
    //返回参数值
    return result ? decodeURIComponent(result[2]) : null;
  };

  //+------
}

//持续更新
