Hello,
I have sample application that I would like the validate to be trigger when a button is click... In the example, I would like to see the error message if the validate button is press and the user did not complete the form

This is the validation that work for ng-disable... but now I want the button to always be clickable but do not proceed if the field are empty

 ng-disabled="myForm.user.$dirty && myForm.user.$invalid ||  
                myForm.email.$dirty && myForm.email.$invalid"

Open in new window
