AngularJS ngRepeat:如何区分偶/奇元素? [英] AngularJS ngRepeat: how to differentiate even/odd elements?

问题描述

我是angel的新手，正在尝试执行以下操作:

I'm new to angular and trying to do the following:

<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>

对于以上代码，两个 ng-if 均已通过.我在哪里犯错?

for the above code, both ng-if is passing. Where I'm making mistake?

推荐答案

尝试使用 $ even 和 $ odd 属性.请参考文档.

Try $even and $odd properties. Refer the documentation.
