CSS代码:
1 .strike { 2 text-decoration: line-through; 3 } 4 .bold { 5 font-weight: bold; 6 } 7 .red { 8 color: red; 9 }
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
3.数组语法
<p ng-class="[style1, style2, style3]">Using Array Syntax</p> <input ng-model="style1" type="text" placeholder="bold, strike or red"></br> <input ng-model="style2" type="text" placeholder="bold, strike or red"></br> <input ng-model="style3" type="text" placeholder="bold, strike or red"></br> </hr>
4.ngClassEven与ngClassOdd
css:
.odd {
color: red;
}
.even {
color: blue;
}
<ol ng-init="names=[\'John\', \'Mary\', \'Cate\', \'Suz\']"> <li ng-repeat="name in names"> <span ng-class-odd="\'odd\'" ng-class-even="\'even\'"> {{name}} </span> </li> </ol>
