1.映射语法
1 <p ng-class="{strike: deleted, bold: important, red: error}">Map Syntax Example</p> 2 <input type="checkbox" ng-model="deleted"> deleted (apply "strike" class)<br> 3 <input type="checkbox" ng-model="important"> important (apply "bold" class)<br> 4 <input type="checkbox" ng-model="error"> error (apply "red" class) 5 <hr>
//strike, bold, improtant为true时，将分别引用类名deleted, bold, error
2.字符串语法
<p ng-class="style">Using String Syntax</p> <input ng-model="style" type="text" placeholder="bold strike red"> </hr>
//类名多个有效，空间隔开即可
