The issue with Angular JS is that it fails to refresh the select and input fields after selecting a date

Currently utilizing Angular JS and Bootstrap, I have a query regarding updating the input for a datepicker calendar and a select from a function.

The values are being successfully updated, however, they do not reflect on their respective inputs.

It seems like I am updating the model but failing to update the view. Updating the model from the view works perfectly, but not vice versa.

In an interesting turn of events, if I update a checkbox by clicking ... Surprise! The select and the datepicker calendar get updated.

How can I update the view from my model and ensure this update is visible?

Edit 1:

HTML

<select ng-model = "searchPAI.sistemaSelected" class="form-control" ng-options="sistema.nombreSistema for sistema in listSistemas">
</select>
<p class = "input-group" ng-controller = "dpFechaDesde">
    <input type = "text" class = "form-control" uib-datepicker-popup = "{{format}}" name = "dtInicio" ng-model = "dateFrom" is-open = "popup1.opened" ng-change = "change2()"
    min-date = "minDate" max-date = "maxDate" datepicker-options = "dateOptions" close-text = "Cerrar" clear-text = "Borrar" now-text = "Hoy" />
    <span class="input-group-btn">
        <button type="button" class="btn btn-default" ng-click="open1()"><i class="glyphicon glyphicon-calendar"></i></button>
    </span>                     
</p>

JS:

$scope.searchPAI.sistemaSelected = $scope.listSistemas[id];
$scope.$on("updateFechaDesde", function(){
        $scope.dateFrom = publicDPFactory.date;
        MyVar.data.dtFrom = publicDPFactory.date;
        console.log("publicDPFactory.date: " + publicDPFactory.date);
        console.log("scope.dateFrom: " + $scope.dateFrom);
});

I must highlight that everything functions correctly when updating the model from the view.

Edit 2:

Here's another surprise! As previously mentioned, I update the value from the model but cannot see these changes reflected in the view.

However, with a simple click on "SI" ... Surprise!!! Suddenly, the updated values are visible on the view. You can observe the select and the datepicker now reflecting the updates.

Answer №1

Success! Issue Resolved!

To reflect changes in the model on the view, make sure to implement the following code snippet after updating the model:

$scope.$apply();

Now you will be able to see all the updates immediately!

As demonstrated, there is no need to interact with any other component on the form in order to observe the updated values in the model reflected on the view.
