>输入’Observable< {}>‘不能分配给’Observable’类型,它指向’return o’行; canDeactivate(): Observable<boolean> | boolean {
if (!this.crisis || this.crisis.name === this.editName) {
return true;
}
let p = this.dialogService.confirm('Discard changes?');
let o = Observable.fromPromise(p);
return o;
}
任何人都可以指导我修复这些错误吗？谢谢. 解决方法
你可以试试施法：
canDeactivate(): Observable<boolean> | boolean {
if (!this.crisis || this.crisis.name === this.editName) {
return true;
}
let p = this.dialogService.confirm('Discard changes?');
let o = <Observable<boolean>>Observable.fromPromise(p);
return o;
}
