javascript - 尝试对表中的任意行进行 Zebra 条纹

Question

我有一个表，其中包含由类标记的行。这些行应该是斑马条纹。需要注意的是它们并不总是连续的。

我尝试过按表和类名进行匹配，但最终结果总是不正确。发生的情况是， strip 化将应用于表级别，然后仅在具有该类的行上启用。

我需要改变什么才能让这项工作按我的预期进行？

脚本

function FormatTable()
{
   $("#TableId .arbitrarySelector:nth-child(2n+1)" ).addClass('anotherEquallySpecialRow')
}

HTML

<table id="TableId" onclick="FormatTable()">
    <tr class="arbitrarySelector">
        <td><div class="space">Should be Changed and is</div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should Not be Changed and is Not</div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should be Changed and is</div></td>
    </tr>
    <tr>
        <td><div class="space"></div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should NOT be changed but is</div></td>
    </tr>
    <tr>
        <td><div class="space"></div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should be Changed and is</div></td>
    </tr>
    <tr>
        <td><div class="space"></div></td>
    </tr>
    <tr>
        <td><div class="space"></div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should Not be Changed and is Not</div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should be Changed and is</div></td>
    </tr>
    <tr class="arbitrarySelector">
        <td><div class="space">Should Not be Changed and is Not</div></td>
    </tr>
</table>

你可能让这件事变得太困难了。如果你想做斑马条纹，为什么不直接使用类似 :odd selector 的东西呢？并根据情况更改类(class)。像这样的事情...

// Add zebra striping.
$('.arbitrarySelector:odd').addClass('zebra');

然后 CSS 会是这样的......

.zebra 
{
    background-color: #dddddd;
}
