Angular 5: Argument of type 'void' is not assignment to parameter of type '{} | PromiseLike<{}>'
提问by its.david
This is my code:
这是我的代码:
public resetDefaults() {
return new Promise ((resolve, reject) => {
resolve(
this.resetFilters()
)
}).then(()=> {return this.cachedFilters});
}
private resetFilters() {
}
The this.resetFilters()
is giving me :
该this.resetFilters()
是给我:
Argument of type 'void' is not assignment to parameter of type '{} | PromiseLike<{}>'
“void”类型的参数不是分配给“{}”类型的参数 | PromiseLike<{}>'
I know that if I do:
我知道如果我这样做:
private resetFilters(): Promise<any> {
}
It would get rid of that error but then I have to create a new promise in that method. I just want to be able to call a function without having to add any more promises.
I do need the Promise in resetDefaults()
though
它会摆脱那个错误,但随后我必须在该方法中创建一个新的承诺。我只想能够调用一个函数而不必添加更多的承诺。
我确实需要的无极resetDefaults()
虽然
