在Tampermonkey中使用jQuery [英] Using jQuery in Tampermonkey

问题描述

我正在使用Chrome 27.0.1453.116 m并启用了实验性Javascript"，但是我无法使jQuery在Tampermonkey上运行.

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.

我尝试过:

// ==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;

但是，我在var $ = unsafeWindow.jQuery;行突出显示unsafeWindow时收到一条错误消息，指出在定义unsafeWindow之前已使用它.该如何解决?

However, I get an error on the line var $ = unsafeWindow.jQuery; highlighting unsafeWindow saying unsafeWindow was used before it was defined. How to fix this?

推荐答案

由于Greasemonkey 2.0，您不会(也不能)使用unsafeWindow.jQuery获取jQuery的宿主页实例.您只需使用window.jQuery和// @grant none(或@grant任何其他非jQuery所需的特殊API).

Since Greasemonkey 2.0 you do not (and cannot) use unsafeWindow.jQuery for getting the host page's instance of jQuery. You just use window.jQuery, and // @grant none (or @grant whatever other special APIs you need for non-jQuery things).

当前(2015年2月)Tampermonkey的默认设置似乎与之类似: http://tampermonkey.net/faq.php#Q404

Tampermonkey currently (Feb 2015) seems to work similarly by default settings: http://tampermonkey.net/faq.php#Q404

以下旧的过时答案:

添加指令// @grant unsafeWindow.另外，如果你得到 您从宿主窗口对象获得的jQuery引用，则不需要 @require行.

Add a directive // @grant unsafeWindow. Also, if you are getting your jQuery reference from the host window object, you won't need the @require line.
