我有一些重复的卡片，从 json 中检索。除了 md-switch 之外，一切正常。我想要切换按钮，它可以更改(不可见)状态和图像。但它改变了所有的图片。为什么？

angular.module('MyApp',['ngMaterial']).controller('SwitchDemoCtrl', function($scope) {
  $scope.data = {
    cb1: true
  }; 

  
    $scope.contacts = [
        { name: 'Text 1', phone: '0101 423' },
        { name: 'Text 2', phone: '0101 6123' },
        { name: 'Text 3', phone: '0101 2223' },
        { name: 'Text 4', phone: '0101 4512' },
        { name: 'Text 5', phone: '0101 2135' },
        { name: 'Text 6', phone: '0101 7' },
        { name: 'Text 7', phone: '0101 1235' }
	];
 
  });

定义 cb2 内部触点并将其用于每个开关。请查看下面的工作演示。

angular.module('MyApp',['ngMaterial']).controller('SwitchDemoCtrl', function($scope) {
        
    $scope.contacts = [
        { name: 'Text 1', phone: '0101 423', cb2: false},
        { name: 'Text 2', phone: '0101 6123', cb2: false },
        { name: 'Text 3', phone: '0101 2223', cb2: false },
        { name: 'Text 4', phone: '0101 4512', cb2: false },
        { name: 'Text 5', phone: '0101 2135', cb2: false },
        { name: 'Text 6', phone: '0101 7', cb2: false },
        { name: 'Text 7', phone: '0101 1235', cb2: false }
	];
