Firefox扩展中的jQuery

Question

I would like to include jQuery in a Firefox extension.

I add the following line of code to import the jQuery file:

Components.utils.import("resource://js/jquery.js", window.content.document);

Firefox runs the file immediately after importing. The jQuery file looks like this with an anonymous closures:

 (function( window, undefined ) {
        ...bunch of code....
       _jQuery = window.jQuery,
 })(window);

When the extension runs there is an error "window is not defined". What is a way to give jQuery access to the window?

Answer 1

将此文件写入* .xul文件以包含jQuery。

<script type="application/x-javascript" src="toolbar.js"></script>

Answer 2

Not tested, but on normal websites, jQuery is loaded into the context of window . Therefore, you have to use window.content as scope:

Components.utils.import("resource://js/jquery.js", window.content);

window.content.document does not contain a property window .

Answer 3

如果它与greasemonkey userjs相同，请尝试使用unsafeWindow ，而不是window 。
