AngularJS | ng-class-even指令用法示例 _ng-class-even

ng-class-even指令在AngularJS中, 用于在HTML元素的所有均匀外观上指定CSS类。它用于在每个偶数HTML元素上动态绑定类。如果ng-class-even指令中的表达式返回true, 则仅添加该类, 否则不添加。要使ng-class-even指令有效, 必须使用ng-repeat指令。所有HTML元素都支持它。
【AngularJS | ng-class-even指令用法示例】语法如下：

< element ng-class-even="expression"> Contents... < /element>
