我想在 firefox 扩展中使用 jQuery，我在 xul 文件中导入了这个库，如下所示:
I want to use jQuery inside a firefox extension, I imported the library in the xul file like this:
<script type="application/x-javascript" src="chrome://myExtension/content/jquery.js"> </script>但是 $() 函数在 xul 文件中无法识别，jQuery() 也无法识别.
but the $() function is not recognized in the xul file neither do the jQuery().
我用谷歌搜索了这个问题并找到了一些解决方案，但没有人与我合作:gluei/blog/view/using-jquery-inside-your-firefox-extensionforums.mozillazine/viewtopic.php?f=19&t=989465
I googled about the problem and found some solutions but no one did work with me: gluei/blog/view/using-jquery-inside-your-firefox-extension forums.mozillazine/viewtopic.php?f=19&t=989465
我还尝试将content.document"对象(引用document"对象)作为上下文参数传递给 jQuery 函数，如下所示:
I've also tried to pass the 'content.document' object(which refrences the 'document' object) as the context parameter to the jQuery function like this:
$('img',content.document);但还是不行，有没有人遇到过这个问题?
but still not working, does any one came across this problem before?
推荐答案我使用以下 example.xul:
<?xml version="1.0"?> <overlay id="example" xmlns="www.mozilla/keymaster/gatekeeper/there.is.only.xul"> <head></head> <script type="application/x-javascript" src="jquery.js"></script> <script type="application/x-javascript" src="example.js"></script> </overlay>这里是一个 example.js
(function() { jQuery.noConflict(); $ = function(selector,context) { return new jQuery.fn.init(selector,context||example.doc); }; $.fn = $.prototype = jQuery.fn; example = new function(){}; example.log = function() { Firebug.Console.logFormatted(arguments,null,"log"); }; example.run = function(doc,aEvent) { // Check for website if (!doc.location.href.match(/^(.*.)?stackoverflow(/.*)?$/i)) return; // Check if already loaded if (doc.getElementById("plugin-example")) return; // Setup this.win = aEvent.target.defaultView.wrappedJSObject; this.doc = doc; // Hello World this.main = main = $('<div id="plugin-example">').appendTo(doc.body).html('Example Loaded!'); main.css({ background:'#FFF',color:'#000',position:'absolute',top:0,left:0,padding:8 }); main.html(main.html() + ' - jQuery <b>' + $.fn.jquery + '</b>'); }; // Bind Plugin var delay = function(aEvent) { var doc = aEvent.originalTarget; setTimeout(function() { example.run(doc,aEvent); }, 1); }; var load = function() { gBrowser.addEventListener("DOMContentLoaded", delay, true); }; window.addEventListener("pageshow", load, false); })();更多推荐
