javascript - 如何初始化 ElementRef Angular - typescript

Question

当我使用@ViewChild('serachField', { static: false }) serachField: ElementRef<HTMLInputElement>我得到错误

Property 'serachField' has no initializer and is not definitely assigned in the constructor.

我通常初始化变量，但我不确定在这种情况下如何做
我试过了

@ViewChild('serachField', { static: false }) serachField: ElementRef<HTMLInputElement> = new ElementRef<HTMLInputElement>(--unsure what the parameter should be--)

我得到:

Expected 1 arguments, but got 0.ts(2554)
core.d.ts(2253, 17): An argument for 'nativeElement' was not provided.

Answer 1

谢谢@Isbn
我用了:

@ViewChild('serachField', { static: false }) serachField: ElementRef<HTMLInputElement> = {} as ElementRef;
