问题 <input #gb type="text" pInputText class="ui-widget ui-text" ngModel (ngModelChange)="clearFilter($event)"> I didn't assign any model name to ngModel directive in my code, but Angular 2 accepts this, while AngularJS (1.x) doesn't.

A proper way of coding this would be to check if the object exists first, and only then show the object if it

问题 I'm using this <textarea class="notes" placeholder="Placeholder Text" style="height: 630px;" ng-model="notes"></textarea> and from what I can understand ng-model="notes" means that the textarea is assigned whatever $scope.notes is. This works correctly, however whenever I edit the text in the textarea, isn't $scope.notes supposed to change as well? When I use this button: <button ng-click="saveNotes(notes)"></button> The value of "notes" is always the original $scope.notes value and not the

问题 This should be a very common problem, invoking an ng-model to parse the data into form (DOM) after which the modified checkbox's ng-checked will be translated back to data values so to be saved back on the server. I have two check boxes respectively <table><tbody> <tr> <td align="left">To be ignored</td><td align="left">Yes <input type="checkbox" ng-model="nm_ignore" /></td> <td></td> </tr> <tr> <td align="left">To be excluded</td><td align="left">Yes <input type="checkbox" ng-model="nm
