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> <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> <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"); $scope.hasAll = false; } } })
3、效果图
4、循环列表，判断索引添加样式
<div> <ul> <li ng-repeat="item in rootList" ng-class="{true: 'cur', false: ''}[$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> <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>
