我使用以下问题中的代码将 YouTube 视频插入页面：如何将 YouTube 播放器的大小从缩略图大小调整为“正常”大小。
给定以下html：
<dl>
<dt>Thoughts of Sacrament</dt>
<dd><div class="placeholder"><img src="img/H5ZEYFgmfYo.png" id="H5ZEYFgmfYo" /></div><div class="close">x</div><p>There is no purpose to this text, it's just here in order to provide a frame of visual reference while I work upon the code behind this here 'page,' still: I hope you enjoy, uh...looking.</p></dd>
<dt>Sanity falling</dt>
<dd><img src="img/2ieLb3RAblA.png" id="2ieLb3RAblA" /></dd>
</dl>
我希望以下 jQuery 应该删除.placeholder包含 YouTube 视频的 div：
$(document).ready(function(){
// ...Other code to insert the YouTube...
$("div.close").click(function() {
$(this).sibling("div").remove();
// $(this).parent().empty();
});
});
最终，我的目标是“反转”原始动画，然后将 youtube 视频换成原始动画.png，但我无法访问相关的 div。注释掉的代码有效，并清空了父元素，但我似乎无法访问兄弟.placeholder。
任何帮助将不胜感激，在此先感谢=）
更新：
到目前为止，我没有比以前更进一步，当前页面在这里结束，该页面的代码如下：
<?xml version="1.0" encoding="utf-8"?>

<!--
Currently -almost- works
- unfortunately the 'close' option doesn't care
if the video's been played or not (and will remove the picture if it's there).
- the close button also (tries?) to animate the flash object and then drops
the replacement image in. Looks wrong.
On updating the page, the image -after closing/removing the video
is no longer 'clickable'
-->

$(document).ready(function(){
$(".placeholder img").click(function () {
var videoID = $(this).attr("id");
$(this).animate({

$("div.close").click(function() {

$(this).parent().children("div .placeholder").animate({

你会注意到 div 的过度使用（使用是因为我认为 - 出于某种原因 - 它可能会使导航 DOM 更容易：据我所知，它没有），对此我只能道歉。我会为Meyer、Molly和Cederholm做出必要的牺牲。
