请问小程序Promise怎么使用》
function1: function () {
return new Promise(function (resolve, reject) {
manager.stop()
resolve();
})
},
function2: function () {
var that = this;
that.function1().then(function (resolve) {
console.log(“globalData2”, app.globalData.result)
var result = getApp().globalData.result
that.setData({
result: result
})
})
我在程序中这样写 为什么没反应 ？还是先funcion2执行再function1呀 ？小白求助！

按照你这个写法，你将function1放在function2里调用了，那么就得在适当的地方去调用function2才能有效果。
function1: function () { return new Promise(function (resolve, reject) { manager.stop() resolve(); });},function2: function () { let that = this; this.function1() .then(function (resolve) { console.log("globalData2", app.globalData.result); let result = getApp().globalData.result; that.setData({ result, });});onLoad() { this.function2();} |
