小编var*_*max的帖子

我有这个代码:

var myFirstPromise2 = new Promise((resolve, reject) => {
    //setTimeout models an operation that takes a long time
    setTimeout(function(){console.log('finishTimeout')},60000);
    resolve('success');
});

myFirstPromise2.then((successMessage) => {
    console.log('yay '+successMessage);
});

输出是:

yay success 
finishTimeout

我希望resolve()在冗长的操作完成后执行,以便输出反转.

我也对一般的承诺感到困惑.上面的代码与简单地执行此操作没有区别:

setTimeout(function(){console.log('finishTimeout')},60000);
console.log('yay success');

编辑:放入resolve()内部之间的区别是什么setTimeout:

setTimeout(function() {
    console.log('finishTimeout')
    console.log("yay success")
},60000)
