现在任何问题或任何答案如此，当你在任何答案/问题上移动光标在该用户的签名上时，具有超过1000次重复的用户具有以下效果，如下所示：

因此可以对天赋代码进行此效果，所以当我将该代码粘贴到我的网站上时，它会给出我的天赋的扩展视图吗？

Answer 1

这是我目前的代码......我必须删除其余部分以使其适合。

- 我清理了相当多的代码，但请告诉我是否需要澄清一些内容，因为我不是最好的记录。

这是名为“so.js”的js

/*
 * author: craniumonempty
 * javascript/jquery for user dropdown over user flair for user sites (designed with stackoverflow, but should be easily adapted)
 * to be used in conjuntion with php
 *
 * Nothing to be called, it searches for all stackoverflow flair (as given by website with <a><img></a>) on page
 *
 * This requires JQquery 1.5 or newer due to the $.getJSON().success() function call
 */

/* Minimal html to test:

    <html><head>
    <script type="text/javascript" src="jquery-1.7.1.min.js"></script>
    <script type="text/javascript" src="so.js"></script>
    </head><body>

    </a>
    </body></html>

Note, jquery >= 1.5 and tag (<a><img></a>) with the stackoverflow site. It searches for that tag.
Change the jquery if you want to search for something else.
