javascript - 隐藏类中的第二个元素

转载作者：可可西里更新时间：2023-11-01 13:34:36

<span class="fileactions">
    <a href="#" class="action" data-action="Download" original-title="">
        <img class="svg" src="/login/owncloud/core/img/actions/download.svg"> Download
    </a>
    <a href="#" class="action" data-action="Share" original-title="">
        <img class="svg" src="/login/owncloud/core/img/actions/share.svg"> Share
    </a>
</span>

类文件操作包含 2 个链接元素。我想删除第二个。

我试过用这个:

.fileactions a:nth-child(2) {
    display:none;
}

.fileactions [data-action="Share"] {
    display: none;
}

但这些都不起作用。

我正在使用 owncloud，并希望在以用户身份登录时隐藏共享文件的选项。

最佳答案

如评论所述，您的选择器 .fileactions a:nth-child(2) 应该可以正常工作，也许您没有共享更多 HTML，使第二个 a 不是第二个 child ？

如果是这样，您可以尝试 .fileactions > a:nth-of-type(2)，或者更好的是，根据数据属性进行选择:

.fileactions > a[data-action="Share"] {
    display:none;
}
