有人能告诉我清单2中的错误在哪里吗?

一个潜在的问题是,使用清单2时,您需要在线脚本。让它工作的一种方法是使用脚本的内容创建一个单独的popup.js
文件,然后将popup.html
更改为如下所示:
<html>
<head>
<script type="text/javascript" src="popup.js"></script>
</head>
<body>
<h1>CC.Cr</h1>
<p>Short URL:</p>
<p id="error"></p>
<p>
<input type="text" id="shortUrl"/>
<img src="loader.gif" id="loader" alt="" />
</p>
<p id="copied">
Copied to clipboard.
</p>
</body>
</html>
