Using jQuery in Tampermonkey
提问by Michael Jarvis
I'm using Chrome 27.0.1453.116 m and have enabled "Experimental Javascript", however I'm unable to get jQuery to run on Tampermonkey.
我正在使用 Chrome 27.0.1453.116 m 并启用了“实验性 Javascript”，但是我无法让 jQuery 在 Tampermonkey 上运行。
I have tried:
我试过了：
// ==UserScript==
// @name My Fancy New Userscript
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js
// ==/UserScript==
var $ = unsafeWindow.jQuery;
var jQuery = unsafeWindow.jQuery;
However, I get an error on the line var $ = unsafeWindow.jQuery;highlighting unsafeWindowsaying unsafeWindow was used before it was defined. How to fix this?
但是，我在var $ = unsafeWindow.jQuery;高亮显示unsafeWindowunsafeWindow 在定义之前使用了该行时收到错误消息。如何解决这个问题？

EDIT: Since Greasemonkey 2.0 you do not (and cannot) use unsafeWindow.jQueryfor getting the host page's instance of jQuery. You just use window.jQuery, and // @grant none(or @grantwhatever other special APIs you need for non-jQuery things).
编辑：从 Greasemonkey 2.0 开始，您不会（也不能）unsafeWindow.jQuery用于获取主机页面的 jQuery 实例。您只需使用window.jQuery, and // @grant none（或@grant任何其他非 jQuery 事物所需的特殊 API）。

Tampermonkey currently (Feb 2015) seems to work similarly by default settings: http://tampermonkey.net/faq.php#Q404
Tampermonkey 当前（2015 年 2 月）在默认设置下似乎工作类似：http://tampermonkey.net/faq.php#Q404
old outdated answer below:
旧的过时答案如下：
Add a directive
// @grant unsafeWindow. Also, if you are getting your jQuery reference from the host window object, you won't need the@requireline.
添加指令
// @grant unsafeWindow。此外，如果您从宿主窗口对象获取 jQuery 引用，则不需要该@require行。
