AngularJS ngRepeat : how to differentiate even/odd elements?

Question

我是 angular 的新手，并尝试执行以下操作:

<tr data-ng-repeat="element in awesomeThings">
<div ng-if="$index %2 == 0">
    <td class="even">
        <a href="#">
            {{element}}
        </a>
    </td>
</div>
<div ng-if="$index %2 != 0">
    <td class="odd">
        <a href="#">
            {{element}}
        </a>
    </td>
</div>
</tr>

对于上面的代码，两个 ng-if正在通过。我哪里出错了？

试试 $even和 $odd属性。引用 documentation .

</div>
<div ng-if="$odd">
