Utilizing Nested Partials and Accessing Object References in AngularJS

I am facing an issue with a partial view that appears like this:

<div ng-if="activeItem.typeOf == 'text'">
     <div onload="item=activeItem" ng-include="'views/app-builder/text.html'"></div>
</div>

Whenever a user clicks a button, I have a controller method that resets the activeItem.

 $scope.showDetails = function(item){
        $scope.activeItem = item;
 };

The structure of activeItem is as follows:

{  name: "Candy", typeOf: "text" }

Initially, everything works fine. However, after the first time, the nested partial's active item is not updated because the reference in onload remains unchanged. What would be the correct approach to address this issue in Angular?

Answer №1

To ensure AngularJS can effectively monitor changes using prototypes, it is recommended to use references in your code. This is a common practice in JavaScript. Consider the following strategy:

$scope.currentSelection = {};
$scope.currentSelection.details = {
    title: "Book1",
    genre: "Fiction1"
}

$scope.displayInfo = function (selection) {
    $scope.currentSelection.details = selection;
}

When it comes to displaying information in the UI

{{selection.details.title}}
