.it{color:#ff7300;margin:10px;}

<pre>
1.字符串数组形式。
< div ng-class="{true: ‘active‘, false: ‘inactive‘}[isActive]">< /div>
相当于对这个求值：({true: ‘active‘, false: ‘inactive‘})[false] ({true: ‘active‘, false: ‘inactive‘})[true]
即 var ct={true: ‘active‘, false: ‘inactive‘};
ct[true]或ct[false]得到值为‘active‘或 ‘inactive‘
2.scope变量绑定，（不推荐使用）
$scope.test =“classname”;
< div class=”{{test}}”>< /div>
3. 象key/value方式，处理class混合
< div ng-class="{‘selected‘: isSelected, ‘car‘: isCar}">< /div>
</pre>
<div ng-controller="cartController">
<div class="it {{test}}">scope变量绑定</div>
<div class="it" ng-click="selM()" ng-class="{true: ‘curr‘, false: ‘‘}[isActive]">字符串数组形式，单击</div>
<div class="it" ng-class="{‘fs18‘: isFs, ‘pd20‘:isPd }" ng-click="selM3()">对象key/value方式，处理class混合..将应用it fs18 pd20 。其中it是默认的</div>
</div>
<script>
var app=angular.module(‘firstApp‘,[]);//app模块名
app.controller(‘cartController‘,function($scope){
$scope.test=‘curr‘;//直接方式。
$scope.isActive=false;
$scope.selM=function(){
$scope.isActive=true;
console.log(‘当前选中否‘,$scope.isActive)
}
//第3种方式
$scope.isFs=false;
$scope.isPd=false;
$scope.selM3=function(){
$scope.isFs=true;
$scope.isPd=true;
}
});
