Well, you could bind each form field to a scope object and $watch the
object for changes
scope.myForm = {
field1: 'initial_value',
field2: null,
field3: false
}
scope.$watch('myForm', function(newFields, oldFields) {
if (newFields.field2.length) {
scope.buttonDisabled = true;
}
else if (!newFields.field3){
scope.buttonDisabled = true;
}
}, true); //notice this tells the $watcher that it's to catch any change
on the object
