Update data from drop down list

Update data from drop down list

1.3k views Asked by AudioBubble At 25 December 2024 at 21:53

How can I update the content of another element when a selection is made from a drop down list?

I want to update:

the description fields,
price and ID in the block details.

Here is the link of plunker I created with the code (must manually navigate to version dated Jun 13, 2015 2:49:35 PM), which is also in the following snippet.

(function() {

  'use strict';

  var app = angular.module('testApp', []);
  
  
  app.controller('testCtrl', ['$scope', function($scope) {
    
    
    $scope.variants = [{
      'id': 'p-12345',
      'url': 'section/food/product/p-12345',
      'title': 'Product 1',
      'price': '£21.15 - 21x15',
      'description': 'lorem ipsum dolor'
    }, {
      'id': 'p-12366',
      'url': 'section/food/product/p-12366',
      'title': 'Product 2',
      'price': '£11.15 - 10Kg',
      'description': 'lorem ipsum dolor'
    }, {
      'id': 'p-12364',
      'url': 'section/food/product/p-12364',
      'title': 'Product 3',
      'price': '£67.15 - 60Kg',
      'description': 'lorem ipsum dolor'
    }];


  }]);


})(window, angular);

Problem solved!!! :) :)

I've updated the code in Plunker... In case anyone has the same problem.

I only had to change this:

<div class="form-group">
   <select id="selectVariant" ng-model="selectItem" class="form-control">
      <option selected="selected" disabled="disabled">Choose one product...</option>
      <option ng-repeat="variant in variants" value="{{variant.url}}">{{variant.title}}</option>
   </select>
</div>

To this:

<div class="form-group">
  <select id="selectVariant" ng-model="productSelect" ng-options="product as product.price for product in variants track by product.url" class="form-control">
     <option selected="selected" disabled="disabled">Choose one product...</option>
  </select>
</div>

(function() {

  'use strict';

  var app = angular.module('testApp', []);
  
  
  app.controller('testCtrl', ['$scope', function($scope) {
    
    
    $scope.variants = [{
      'id': 'p-12345',
      'url': 'section/food/product/p-12345',
      'title': 'Product 1',
      'price': '£21.15 - 21x15',
      'description': 'lorem ipsum dolor'
    }, {
      'id': 'p-12366',
      'url': 'section/food/product/p-12366',
      'title': 'Product 2',
      'price': '£11.15 - 10Kg',
      'description': 'lorem ipsum dolor'
    }, {
      'id': 'p-12364',
      'url': 'section/food/product/p-12364',
      'title': 'Product 3',
      'price': '£67.15 - 60Kg',
      'description': 'lorem ipsum dolor'
    }];


  }]);


})(window, angular);
