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


<ion-view> 
 <ion-content> 
 <div class="button-bar"> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[isFirst]" ng-click="isFirst = !isFirst">First</div> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[isSecond]" ng-click="isSecond = !isSecond">Second</div> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[isThird]" ng-click="isThird = !isThird">Third</div> 
 </div> 
 <br><br> 
 <div class="button-bar"> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[hasAll]" ng-click="toggleAll()">All</div> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[hasFirst]" ng-click="toggleFirst()">First</div> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[hasSecond]" ng-click="toggleSecond()">Second</div> 
 <div ng-class="{true: 'bgstyle-check', false: 'bgstyle'}[hasThird]" ng-click="toggleThird()">Third</div> 
 </div> 
 </ion-content> 
</ion-view> 
<style> 
 .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;} 
</style> 

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; 
 } 
 
 } 
}) 


3、效果图

4、循环列表,判断索引添加样式


<div class="category-tab "> 
 <ul> 
 <li ng-repeat="item in rootList" ng-class="{true: 'cur', false: ''}[$index+1===1]"> 
 <a href="">{{item.CategoryName}}</a> 
 </li> 
 <li><a href="">热门推荐</a></li> 
 <li><a href="">热门推荐</a> </li> 
 </ul> 
</div> 

*、


<ion-item class="item-divider"> 
 <i ng-class="{true: 'icon ion-tips mr10', false: 'iconfont icon-shangdian text-orange mr10'}[item.VendorId==0]"> 
 <element ng-show="item.VendorId==0">合作</element></i>{{item.VendorName}} 
</ion-item>
