ngModel is displaying the value, however it is still considered empty by required validation. Adding an empty space after the value resolves this issue.
Snippet to retrieve the name
<div (click)="getName(item.name)"></div>
<input matInput [(ngModel)]="data.name" value="{{name}}">
Component.ts
name: string;
data: Data
getName(nm) {
this.name = nm;
}
This seems just right to me
<input matInput [(ngModel)]="username">Avoid using both [(ngModel)] and value properties simultaneously. The use of [] within [(ngModel)] already sets the input's value. Choose between (ngModel) and either value, [value], or [(ngModel)]
Can you explain the relationship between data.name and ngModel?
I believe it is not necessary to use the value attribute. Instead, bind the component variable name to ngModel as shown below
<div (click)="getName('hello')">Click</div>
<input matInput [(ngModel)]="name"> {{name}}
In your component,
name: string;
getName(nm) {
this.name = nm;
}
Click the button, and you will notice that the input field displays 'hello'
Angular 7 has deprecated [(ngModel)] in favor of using formcontrol for better control
