var app=getApp();

Page({

    data:{

        backUrl:null,

        loginName:null,

        passWord:null

    },

    onLoad:function(options){

        this.setData({

        backUrl:null

    });

    // 页面初始化 options为页面跳转所带来的参数

    //console.log(options.backUrl);

    this.setData({

        backUrl:options.backUrl

    });

    },

    inputClick:function(event){

        //动态 对 paga.data 进行赋值

        //id与 数据项 一一对应

        var objId=event.currentTarget.id;

        var paraObj={};

        paraObj[objId]=event.detail.value;

        this.setData(paraObj);

        //console.log(event.currentTarget.id);

        //console.log(this.data);

    },

    onReady:function(){

        // 页面渲染完成

    },

    onShow:function(){

        // 页面显示

    },
