详解AngularJS ng-class样式切换

整理文档，搜刮出一个详解AngularJS ng-class样式切换，稍微整理精简一下做下分享。

1、HTML

 
   
     
      First 
      Second 
      Third 
     
    

 
     
      All 
      First 
      Second 
      Third 
     
   
 
 
  .bgstyle {background-color: #8f8f8f;width: 100%;height: 20px;margin: 2px 0 2px 0;text-align: center;} 
  .bgstyle-check {background-color: #ff3b30;width: 100%;height: 20px;margin: 2px 0 2px 0;text-align: center;} 
 

2、controller

appControllers.controller('TestlCtrl', function ($scope, $state) { 
  $scope.isFirst = false; 
  $scope.isSecond = false; 
  $scope.isThird = false; 
 
 
  $scope.hasAll = false; 
  $scope.hasFirst = false; 
  $scope.hasSecond = false; 
  $scope.hasThird = false; 
 
  $scope.toggleAll = function () { 
    $scope.hasAll = !$scope.hasAll; 
    console.log($scope.hasAll); 
    var dynamicValue = $scope.hasAll; 
    $scope.hasFirst = dynamicValue; 
    $scope.hasSecond = dynamicValue; 
    $scope.hasThird = dynamicValue; 
  } 
 
  $scope.toggleFirst = function () { 
    $scope.hasFirst = !$scope.hasFirst; 
    checkAll(); 
  } 
 
  $scope.toggleSecond = function () { 
    $scope.hasSecond = !$scope.hasSecond; 
    checkAll(); 
  } 
 
  $scope.toggleThird = function () { 
    $scope.hasThird = !$scope.hasThird; 
    checkAll(); 
  } 
 
  function checkAll() { 
    if ($scope.hasFirst == true && $scope.hasSecond == true && $scope.hasThird == true) { 
      console.log("123ok"); 
      $scope.hasAll = true; 
    } else { 
      console.log("123no"); 
      $scope.hasAll = false; 
    } 
 
  } 
})
