Dear Like Kende,
Thanks for your respone.
You are right, having watch on object collection, I can enable/disable save
button.
Please tell me one thing more that how can we store the form controls value
after page load into object collection inside the angularjs controller.
So that I can find
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;
}
