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>
