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; 
    } 
 
  } 
})

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>
