问题 I have a question about how to avoid watchers when you have readonly input textbox in AngularJS. I have created plunker for it : plunker link : OneWay Binding using ng-value This shows that even when I am using ng-value for readonly input text, still a watcher has been added for it. I simple want to avoid watchers when there are readonly controls, I am asking this because in my enterprise application, even for readonly page I have more-than 200 readonly controls and watcher count there is

As far as i understood ng-model sets the value for that particular element in which the model is been assigned. given that how is ng-value different from ng-model? It works in conjunction with ng-model; for radios and selects, it is the value that is set to the ng-model when that item is selected. Use it as an alternative to the 'value' attribute of the element, which will always store a string value to the associated ng-model. In the context of radio buttons, it allows you to use non-string values. For instance, if you have the radio buttons 'Yes' and 'No' (or equivalent) with values 'true'
