Viewchild 为 null

Question

(Angular 9) I need to use ViewChield().This is my html:

<input type="text" pInputText [(ngModel)]="code" #inputStudent/>

in my ts I do:

    @ViewChild('inputStudent', { read: ElementRef }) someInput: Input;
....

ngAfterViewChecked() {
    if (this.someInput != null) {
      console.log(this.someInput);
    } else {
      console.log("object null;");
    }

  }

the problem is that my ViewChild is null because console prints me "object null;" .Anyone can help me?

Answer 1

@ViewChild("inputStudent",{ static:true}) someInput: ElementRef;
....
console.log(this.someInput.nativeElement.value);
