What is scope.$modelValue in AngularJS?
I am reading here: https://groups.google.com/forum/#!topic/angular/ZcA4eOttQzA
As for knowing when ngModel's value changes, there are two ways I've seen to do it. One is by overriding ngModelController's $render function. Another way, which has proven more reliable in my experience, is to use scope.$watch coupled with a function, as alluded to above. For example:
require: "ngModel", link: function link(scope, element, attrs, ngModelCtrl) { scope.$watch(function () { return scope.$modelValue; }, function (value) { // Do something with updated model value... }); }
I tried this in my code but the only time it fires is at the start. Can someone explain what scope.$modelValue is exactly?
$modelValue: The value in the model, exposed to your controller.
There are two views of a ngModel data. The $viewValue is the view at DOM . $modelView is what the controller has actual value of the model.
