问题描述
我知道他们使用的是 jQuery 插件，但我似乎无法找到他们使用的是哪个插件.特别是，我正在寻找的是具有与 SO 的自动完成功能完全相同的功能的自动完成功能，它会在输入的每个新单词时执行 AJAX 命令，并允许您从下拉列表中选择一个.
I know they're using a jQuery plugin, but I can't seem to find which one they used. In particular, what I'm looking for is autocomplete with exactly the same functionality as SO's autocomplete, where it will perform an AJAX command with each new word typed in and allow you to select one from a dropdown.
推荐答案

Note that the tag editor has been completely re-written now, and no longer resembles the original, simple text box w/ suggestion drop-down that adorned the site for nearly three years.
