如何在 angular 中找到输入的类型？

Question

Sorry I'm a beginner and I can't find how to get the input type in angular. This is the piece of code i have written:

passwordVisibilityToggle() {

var x = document.getElementById("password");
var passwordEye = document.getElementById("password-eye");

if (x.type === 'password') {
  x.type = "text";
  passwordEye?.classList.remove("off");
  passwordEye?.classList.add("on");
 } else {
   x.type = "password";
   passwordEye?.classList.remove("on");
  passwordEye?.classList.add("off");
 }

}

When I use typeof(x) it gives me this: This condition will always return 'false' since the types '"string" | "number" | "bigint" | "boolean" | "symbol" | "undefined" | "object" | "function"' and '"password"' have no overlap.ts(2367) Any advice would be appreciated

Answer 1

You have to add a template reference on the input like this

<input #someInput ...

Then reference the input in the TypeScript file with the @ViewChild annotation:

@ViewChild('someInput') input: ElementRef;

Then you'll be able to check the type of the input anywhere in the code with this:

(this.input.nativeElement as HTMLInputElement).type === 'password';

If your question is about querying all of the inputs then add the same template reference on all of them, then use:

@ViewChildren('someInput') inputs!: QueryList<ElementRef>
