thirdScriptError

Cannot read property 'inviteCode' of undefined;at pages/index/index page lifeCycleMethod onLoad function

TypeError: Cannot read property 'inviteCode' of undefined

报错代码为:

onLoad: function (options) {

var page = this;

//分享获取参数“邀请码”,存为全局变量

// console.log(app.globalData.inviteCode +"-1-1号")

// console.log(options.inviteCode +"-1-2号")

if (app.globalData.inviteCode == '' || app.globalData.inviteCode==undefined){

// console.log(options.inviteCode +"-1-3号")

if (options.inviteCode != '' && options.inviteCode != undefined) {   //读到这一行就报错

app.globalData.inviteCode = options.inviteCode;

}

console.log(app.globalData.inviteCode +"-1-4号")

}

},

    optionsapp.globalData有一个为undefined,看下你的app.js?还有你的onShow?

      onShow: function () {

      var page=this;

      page.onLoad();

      },

      我就是想,对当前页面进行一些JS操作 ,重新加载刷新当前页,除了这种方法,还有其他方法嘛?
