我的代码是这样做的:
wordFormRowClicked = (wf): ng.IPromise<any> => {
var self = this;
if (this.wordFormIdentity != wf.wordFormIdentity) {
return self.wordFormUpdate(wf).then(() => {
this.wordFormIdentity = wf.wordFormIdentity;
})
}
}
self.wordFormUpdate返回一个promise但是当if
条件不匹配时,则不返回promise。
在这种情况下我如何回复承诺?

假设wordFormUpdate是promise:
wordFormRowClicked = (wf): ng.IPromise<any> => {
var self = this;
if (this.wordFormIdentity != wf.wordFormIdentity) {
return self.wordFormUpdate(wf);
}
}
您可以将您的功能运行为:
wordFormRowClicked(someParam).then(() => {
this.wordFormIdentity = wf.wordFormIdentity;
});

只需创建一个承诺并在函数末尾返回它
if (...) {
return ...
}
return new Promise(...)
