Question: How to re-call validation on a single form input ? about angular-validation HOT 7 CLOSED

You can manually call the validate API by using

this.$validationProvider.validate( form )

from angular-validation.

Ye si know you can call that and i do when the user hits SUBMIT, but that call validates the entire form - causes all inputs on the form to have their validation checked and any associated messages will be fired and shown in the UI.

This is not what I asked:

What I asked, was for was way to validation just a single input:

There is a UX business case with my customer that requires:
That ONLY validation on the effected control, related to the input entered (which now causes that previous entry to be invalid) MUST be shown. All other validation messages not related to that changed input MUST NOT display ANY validation messages.

I know the related fields and i want to trigger the validation to fire on the related input ONLY, not the whole form.

yes, you can validate only single one input

<form name="Form">
    <input type="text" name="required" ng-model="required" validator="required"/><input type="text" name="required2" ng-model="required2" validator="required"/>
</form>

<script>
// ...
validationProvider.validate($scope.Form.required)
// ...
</script>

from angular-validation.

Sorry but just to be sure,

You can validate a given named input (covered by validation rules)

i.e.

if ( input_needs_validation && form && input_name) {
    let input = form[input_name];
    validationProvider.validate( input );
}
