Question

如果从下拉列表中进行选择，如何更新其他元素的内容？

我想更新：

描述字段
块详细信息中的价格和ID。

以下是我使用代码创建的plunker的链接（必须手动导航到Jun 13, 2015 2:49:35 PM的版本），该链接也在以下代码段中。

(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);

Answer 1

问题解决了!!! :) :)

我已经更新了Plunker中的代码......万一有人遇到同样的问题。

我只需要改变这个：

<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>

对此：

<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);
