如何在Greasemonkey脚本中包含远程javascript文件? [英] How do I include a remote javascript file in a Greasemonkey script?

问题描述

我正在尝试编写一个Greasemonkey脚本，并且想使用jQuery库来这样做，但是我不太确定如何从网址中包含jQuery来滚动.

I'm trying to write a Greasemonkey script, and would like to use the jQuery library to do so, but I'm not quite sure how I would include jQuery from a web address to get rolling.

我将如何将jQuery(来自Google的网络服务器)包含在油脂猴子脚本中，这样我就可以了:

$(document).ready(function(){
  // Greasemonkey stuff here
});

我希望从此来源获取它:

I'd prefer to get it from this source:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript" charset="utf-8"></script>

更新:感谢您的帮助，答案非常有用.但是，我确实更多地利用了我的GoogleFu，并遇到了以下解决方案: http://joanpiedra.com/jquery/greasemonkey/

Update: Thanks for the help, the answers were very informative. I did, however, utilize my GoogleFu a little more and came across this solution: http://joanpiedra.com/jquery/greasemonkey/

工作就像一个魅力..只需将源代码更新到Google的jQuery托管版本即可完成.

Works like a charm.. just update the source to google's hosted version of jQuery to complete.

推荐答案

在最新版本的oilsmonkey中，推荐的方法是使用@require注释标记.

The recommended way in recent versions of greasemonkey is to use the @require comment tag.

例如

// ==UserScript==
// @name          Hello jQuery
// @namespace     http://www.example.com/
// @description   jQuery test script
// @include       *
// @require       http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js
// ==/UserScript==

但是...请注意，jQuery 1.4.1和1.4.2与该方法不兼容

感谢Paul Tarjan指出了这一点.请参见 jQuery论坛线程.

Thanks Paul Tarjan, for pointing this out. See jQuery forum thread.

也请注意这些@require语义

在安装用户脚本时，Greasemonkey将下载并保留远程文件的本地缓存副本，几乎可以立即读取该副本.缓存的副本与已安装的用户脚本保存在同一文件夹中.不会监视远程文件的更改.

At the time that the user script is installed, Greasemonkey will download and keep a locally cached copy of the remote file that can be read almost instantly. The cached copy is kept in the same folder as your installed user-script. The remote file is not monitored for changes.

请注意，在编写此答案时，仅在安装时读取此@require标记.如果您编辑现有的用户脚本以添加此标记，它将被忽略.您需要卸载并重新安装用户脚本以获取更改.

Please be aware that, at the time of writing this answer, this @require tag is only read at install-time. If you edit an existing user script to add this tag, it will be ignored. You need to uninstall and re-install your user script to pick up the change.
