In the last post I introduced angular 2’s model driven form approach. In this post I’m going to go through how to implement validation rules on a model driven form …
At the moment there seem to be 3 standard validators which pretty much do what they say on the tin:
Here’s some component code that references the standard required and minLength validators:
export class LoginComponent {
loginForm: ControlGroup;
constructor(builder: FormBuilder) {
this.loginForm = builder.group({
userName: ["", Validators.required],
password: ["", Validators.minLength(6)]
});
}
}
You can use Validators.compose to specify multiple validators for a field:
export class LoginComponent {
loginForm: ControlGroup;
constructor(builder: FormBuilder) {
this.loginForm = builder.group({
userName: ["", Validators.required],
password: [
"",
Validators.compose([Validators.minLength(6), Validators.maxLength(12)])
]
});
}
}
