"Adhesive" option in Angular application

Encountering a frustrating issue with an Angular-based frontend app. A select box seems to be stuck and requires double selection to change the option. Below is a code snippet that demonstrates the problem:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script>
  var app = angular.module('myapp', []);

  app.controller('NewsCtrl', function($scope) {
    // Setting news data
    $scope.news = {
      specific_for_dealership: '003'
    };

    // Fetching dealers
    $scope.dealers = [{
      id: 1,
      dealerid: '001',
      name: 'Volvo'
    }, {
      id: 2,
      dealerid: '002',
      name: 'Saab'
    }, {
      id: 3,
      dealerid: '003',
      name: 'Seat'
    }];
  });
</script>
<div ng-app="myapp">
  <div ng-controller="NewsCtrl">
    <form>
      <select name="specific_for_dealership" ng-model="news.specific_for_dealership">
        <option value="">All</option>
        <option ng-repeat="dealer in dealers" ng-selected="news.specific_for_dealership" value="{{ dealer.dealerid }}">{{ dealer.name }}</option>
      </select>
    </form>
  </div>
</div>

Seeking insights on what may have caused this issue and potential solutions to resolve it.

Answer №1

Instead of using ng-selected to choose your option, just rely on ng-model as it handles the selection for you.

The use of ng-selected is causing confusion in the model, hence requiring multiple selections.

 <select name="specific_for_dealership" ng-model="news.specific_for_dealership">
        <option value="">All</option>
        <option ng-repeat="dealer in dealers"  value="{{ dealer.dealerid }}">{{ dealer.name }}</option>
 </select>

I also suggest utilizing ng-options to populate your options list from the object. This will provide more flexibility, allowing you to bind the entire object to the selector rather than just the ID.

<select name="specific_for_dealership" 
     ng-options="dealer.dealerid as dealer.name for dealer in dealers" 
     ng-model="news.specific_for_dealership">
        <option value="">All</option>
</select>

Answer №2

To make sure the correct dealer is selected, use

ng-selected="dealer.dealerid === news.specific_for_dealership"
