What is template referece in Anulgar?
Angular allows creating a reference of DOM element in template By doing this you can reference this variable anywhere in the template.
To create template reference prefix the variable name with #
<input type='text' #input>
Let’s consider the following code snippet
import { Component, ViewChild, ElementRef, OnInit } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<label>Enter Your Email</label>
<input type='text' #input (focus)="input.value='hello'">
`,
styles: []
})
export class AppComponent implements OnInit {
constructor(){
}
ngOnInit(): void {
}
}
In the above example, I have created one template reference for input filed named #input. When the user focuses on the input filed, I am setting the input field value as hello by using the template reference variable. You can also access this variable in the component class using @ViewChild.
