问题是我找不到从 Id 获取视频标题的方法.(例如:ylLzyHk54Z0)

推荐答案
在 javascript 中并非完全可行，因为您正试图从不同的域中获取文档.如果你很乐意加入一些 php 试试这个.测试正常:
Not entirely possible in javascript since you are trying to get a document from a different domain. If you are happy to throw in a bit of php try this. Tested ok:
<?
$vidID = $_POST['vidID'];
$url = "http://gdata.youtube.com/feeds/api/videos/". $vidID;
$doc = new DOMDocument;
$doc->load($url);
$title = $doc->getElementsByTagName("title")->item(0)->nodeValue;
?>
<html>
<head>
<title>Get Video Name</title>
</head>
<body>
<form action="test.php" method="post">
<input type="text" value="ID Here" name="vidID" />
<input type="submit" value="Get Name" />
</form>
<div id="page">URL: [<?= $url ?>]</div>
<div id="title">Title: [<?= $title ?>]</div>
</body>
</html>
