AngularJS ng-class不能使用：hover伪类

Question

悬停psuedoclass似乎不适用于ng-class ...任何想法？这是一个样本：

<style>
    .orange {color:orange}
    .pointer-hover:hover {
        cursor: hand; cursor: pointer;
    }
</style>
<table ng-app>
    <thead>
        <th></th>
        <th>Orange<br />class</th>
        <th>Rollover<br />psuedoclass</th>
    </thead>
    <tr>
        <td>With class tag</td>
        <td class="orange">Orange</td> 
        <td class="pointer-hover">Hover pointer</td>
    </tr><tr>
        <td>With ng-class tag</td>  
        <td ng-class="{orange: 1==true}">Orange</td>  
        <td ng-class="{pointer-hover: 1==true}">Hover pointer</td>
    </tr>
</table>

看看控制台，你有错误。只需用撇号包装您的类名：

"{'pointer-hover': 1==true}"
