const regeneratorRuntime = require('./libs/runtime-module.js')

Page({

 /**
  * 页面的初始数据
  */
 data: {
  num: 0
 },

 /**
  * 生命周期函数--监听页面加载
  */
 async onLoad(options) {
  this.testing()
  this.promiseFn()
  await this.testAsync()
 },

 

 testing() {
  console.log('test')
 },

 promiseFn() {
  this.testPromise().then((res) => {
   console.log(res)
  })
 },

 testPromise() {
  return new Promise((resolve, reject) => {
   setTimeout(() => {
    console.log('Promise handle')
    resolve(123)
   }, 2000)
  })
 },

 async testAsync() {
  const result = await this.testPromise()
  console.log('async test--', result)
 }
})
