慕课Django2.0+小程序技术打造微信小程序助手 出错求助2
出错如下图出错代码如下
// pages/menu/menu.js
const app = getApp()
const cookieUtil = require('../../utils/cookie.js')
const authUtil = require('../../utils/auth.js')
Page({
/**
* 页面的初始数据
*/
data: {
grids: null, // 九宫格内容
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function(options) {
this.updateMenuData()
},
fillIconData: function(data){
var pathPrefix = '../../resources/icons/application/'
for(var index=0; index < data.length; index ++){
var item = data
console.log(item.application)
switch (item.application){
case 'weather':
item.icon = pathPrefix + 'application-weather.png'
console.log('weather')
break

}
})
},
onPullDownRefresh: function() {
wx.showLoading({
title: '加载中',
})
this.updateMenuData()
wx.hideLoading()
}
}) 打印res.data.data看看是啥呢 看样子可能是data未定义，可以打印data出来看看
是不是后端没有设置好？ 是的，res.data.data是空的，没有从后台得到 数据，谢谢各位，正在找原因
