<input type="checkbox" ng-model="important"> important (apply "bold" class)<br>
<input type="checkbox" ng-model="error"> error (apply "red" class)

//strike, bold, improtant为true时，将分别引用类名deleted, bold, error
2.字符串语法

//类名多个有效，空间隔开即可

<input ng-model="style1" type="text" placeholder="bold, strike or red"></br>
<input ng-model="style2" type="text" placeholder="bold, strike or red"></br>
