对于一个小项目，我需要这个小网站，它通过 AJAX 从服务器中提取数据并将其输出，如图所示。然而问题不是 JavaScript，而是纯 HTML+CSS ..

在此处输入图像描述

您可以通过 jsfiddle 点击此页面查看此页面，也可以查看本文末尾引用的引用代码：http: //jsfiddle.net/RdJUM/

该列表是使用以下 html 片段构建的：

<div id="update">
    <ul class="searchresults">
        <li>
            <h2>Caption</h2>
            <div>
                <img src="" alt="" />
                <p>Text</p>
            </div>
        </li>
    </ul>
</div>

它是通过 CSS 格式化的，但重要的部分是：

#update ul li {
    height: 110px;
    overflow: hidden;
    /* ... */       

    /*
    -webkit-transition: height 0.3s ease-out;
    -moz-transition: height 0.3s ease-out;
    -o-transition: height 0.3s ease-out;
    transition: height 0.3s ease-out;
    */
}

#update li:hover {
    height: auto;
}

只要您将过渡注释掉，这就可以正常工作。您将鼠标悬停在文章上，它会将高度缩放为“自动”，从而准确地给出您的内容的高度，仅此而已。但是，如果您取消注释转换，WebKit (Chrome 30, Safari 6) 会产生非常不稳定的效果，完全无法使用。为方便起见，这是未注释版本的 jsfiddle 链接：http: //jsfiddle.net/bQZ7F/

在 Firefox 23 和 Opera 12 中，此转换已停用，因此它的行为就像 CSS 部分不存在一样。

HTML：

<!DOCTYPE html>
<html lang="en">

    <meta charset="utf-8" />
    <title>Live Search</title>
    <link rel="stylesheet" href="mystyle.css" />

    <p>Enter the name or info about a speaker</p>

</div>

感谢您的提示，似乎不使用 JavaScript 是不可能的：

将 CSS 设置为这些值

#update ul li {
    height: 110px;
    /* ... */
}

#update li:hover {
    background: #FFFCE5;
}

JavaScript代码原理：

// Mouse-enter Event
curHeight = $(this).height();
autoHeight = $(this).css('height', 'auto').height();

$(this).height(curHeight).animate({height: autoHeight}, 1000);

// Mouse-leave Event
// same, but vice versa
