onLoad:asyncfunction (options) {constaa =awaitthis.promise1() //没有await console.log(aa) }, promise1(){returnnewPromise((resolve, reject) =>{ resolve('aaaa') }) }, 输出Promise对象 Promise {<resolved>:"aaaa"} onLoad:asyncfunction (options) {constaa =awaitthis.promise1() //有await ...
async用于声明异步的,常常用于处理回调函数。 async返回一个promise的对象,可以直接用.then,.catch来处理结果。 onLoad:function(options) {//声明该方法为异步方法,会返回一个Promise对象asyncfunctiontest(){return'云开发'}//var a = test();//console.log(a)console.log(test()) test().then((res)=>{ ...
在page.js中我们一般把函数定义放在钩子回调函数同层级下,在生命周期函数里面执行 onLoad: function (options) { console.log(this.example()) }, async example(){ console.log("example") return 1 }, 相比于 promise.then,它只是获取 promise 的结果的一个更优雅的语法,同时也更易于读写。 async/await 可...
async onLoad (options) { // 获取首页主题A const data = await Theme.getHomeLocationA() this.setData({ topTheme: data[0] }) } }) 附上目录结构 这样就可以愉快地使用async await形式的Http请求了,彻底摆脱各种callback方法!
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(re...
onload = () => { // 异步Promise调用 asyncMessenger.invoke({ method: "init", data: { user: 123456, token: "blabla..." } }).then(res => console.log("index.html:", res, res)) } // 传统的回调调用 asyncMessenger.addListener("timeInfo", function(data){ console.log("index.html:...
onLoad: function (options) { console.log(this.example()) }, async example(){ console.log("example") return 1 }, 相比于promise.then,它只是获取 promise 的结果的一个更优雅的语法,同时也更易于读写。 async/await可以和Promise.all一起使用 ...
For the typical WinForms dev this may look a bit weird on first glance. After all, we’re calling another method fromOnLoad, and that method never returns because it’s ending up in an endless loop. So, doesOnLoadin this case ever finish? Aren’t we blocking the app here?
callbackName:string: If the script needs to call a global function when finished loading(for example:recaptcha/api.js?onload=callbackName). Please provide the callback name here and it will be autoregistered onwindowfor you. globalName:string: Can provide the name of the global that the scr...
