我想在使用AngularJS指令将鼠标悬停在另一个div上时更改一个div的类.这是我到目前为止
http://jsfiddle.net/E8nM5/38/
HMTL
- <div ng-controller="Ctrl" ng-app>
- <div ng-class="my-class">This div will change class when one hovers over bottom DIV </div>
- <br/>
- <div class="hover-div" ng-mouseenter="my-class = 'highlight'" ng-mouseleave="my-class = 'lowlight'">HOVER OVER ME TO CHANGE THE UPPER DIV's CLASS</div>
- </div>
CSS
- div.highlight {
- padding: 10px;
- background: red;
- color: white;
- }
- div.lowlight {
- padding: 10px;
- background: blue;
- color: white;
- }
- div.hover-div {
- padding: 10px;
- background: green;
- color: white;
- }
JS
- function Ctrl($scope){
- }
有任何想法吗？
将my-class更改为myclass(即破折号导致问题).
- <div ng-controller="Ctrl" ng-app>
- <div ng-class="myclass">This div will change class when one hovers over bottom DIV </div>
- <br/>
- <div class="hover-div" ng-mouseenter="myclass = 'highlight'" ng-mouseleave="myclass = 'lowlight'">HOVER OVER ME TO CHANGE THE UPPER DIV's CLASS</div>
- </div>
更新：表达式中不允许my-class的原因是因为AngularJS将短划线视为减号并试图以这种方式解析它.显然,它无法解析语句my – class =’highlight’.不幸的是,在阅读AngularJS解析器代码后,我找不到一种方法来“帮助”它区分破折号和减号.
