Question

我遇到的问题是，如果第四个项目有一个很长的描述，那么当它超出#features时它会被切断（由于我的设计中有一个严格的高溢出：隐藏。

我希望有人会就如何选择当前项目移至顶端提出建议吗？

这是一个示例网址：forums.wuggawoo.co.uk/example.php基本上它应该从项目1，项目2，项目3，项目4开始，项目1显示其描述。 5秒后，订单应该是项目2，项目3，项目4，项目1，项目2显示其描述。 5秒后订单应该是项目3，项目4，项目1，项目2，项目3显示其描述等等。我刚刚在我发布的链接上更新的代码，有点做了但是由于某种原因它在获得了abit消息之后前几个循环

我建议你这样做：

$('.feature-description').each(function (i,n){
    var parent = $(n).closest('.feature');
    $(n).prependTo(parent);
});

这将把每个“特征描述”放到父母的“.feature”的开头/顶部。在哪里放代码？嗯，这取决于你想要它改变的地方。

如果你想在页面加载时使用它。然后把它放在你的init函数上......

希望有所帮助

jquery，将当前项目移到顶部
