用于类实现:hover伪类的效果, 当用户鼠标移动元素上方时添加几个类名, 鼠标移走时将刚才的 类名移除
用法类似于类名绑定
<body ms-controller="test"> <script> avalon.define({ $id: 'test', aaa: "aaa bbb ccc", bbb: 'ddd', ccc: ['xxx', 'yyy', 'zzz'], ddd: 'eee', toggle: true, toggle2: false }) </script> <span :hover="@aaa">直接引用字符串</span> <span :hover="@ccc">直接引用数组</span> <span :hover="[@aaa, @bbb,'kkk']">使用对象字面量</span> <span :hover="['aaa', 'bbb',(@toggle? 'ccc':'ddd')]">选择性添加类名</span> <span :hover="[@toggle && 'aaa']">选择性添加类名</span> <span :hover="[ @ddd + 4]">动态生成类名</span> </body>
