setData修改了数据，页面为什么没有更新？
// app.js
initAppData() {
return new Promise((resolve, reject) => {
this.getVersion().then(res => { // 版本
console.log('版本：' + this.globalData.appletsVersion)
if (res) this.getLocation().then(res => { // 经纬度
console.log('经纬度：' + this.globalData.location.latitude + ',' + this.globalData.location.longitude)
if (res) this.getStoreList().then(res => { // 门店
console.log('门店：' + this.globalData.storeInfo.storeName)
resolve(true)
})
})
})
})
},
getLocation() {
let that = this
return new Promise((resolve, reject) => {
wx.getLocation({
type: "wgs84",
success(res) {
var location = {
latitude: res.latitude,
longitude: res.longitude
}
that.globalData.location = location
resolve(true)
},
fail(err) {
// 获取经纬度失败
reject(err)
}
})
})
},
//获取门店列表
getStoreList() {
return new Promise((resolve, reject) => {
resolve(true) // 涉及到接口调用，先直接resolve(true)
})
},
// 获取小程序版本
getVersion() {
return new Promise((resolve) => {
resolve(true) // 涉及到接口调用，先直接resolve(true)
})
},
// index.js
const app = getApp()
onShow() {
app.initAppData().then(res => {
this.setData({ // 修改
showDialog: true,
})
console.log(this.data.showDialog)
})
},
