The discrepancy between the ng-model value in the controller and the input field in the HTML

In my HTML code, I have an input field that is linked to a specific value using the ng-model attribute. Initially, any changes made to this ng-model in the controller are accurately reflected in the input field. However, when I manually type something into the input field, the changes in the controller do not update the displayed values on the page.

I attempted to use $scope.$apply() and also tried altering the vieweValue of the input by calling $setVieweValue, but neither approach seemed to work. Upon further investigation during debugging, it seems that the issue lies in the fact that the DOM value of the input element cannot be changed directly (modifying the ng-model does not affect the input value). This was evident when I tested changing the DOM element's value in the Chrome console, which successfully updated the displayed value on the page.

Answer №1

One suggestion is to encapsulate your model inside an object. For example, assume you have a scope variable like this:

$scope.inputValue = "someValue";

and you are using it in your binding like so:

ng-model="inputValue";

Instead, try structuring it like this:

$scope.ob = {inputValue: "someValue"};

Then, in your HTML:

ng-model="ob.inputValue";
