如何在Firefox扩展中使用jQuery [英] How to use jQuery in Firefox Extension
问题描述
<$ c $我想在firefox扩展中使用jQuery,
我在xul文件中导入了这样的库: c>< script type =application / x-javascriptsrc =chrome://myExtension/content/jquery.js> < /脚本>
但是在xul文件中无法识别$()函数,jQuery() / p>
我搜索了这个问题,发现了一些解决方案,但没有人和我合作:

我也尝试将'content.document'对象(它引用'document'对象)作为上下文参数的jQuery功能是这样的:
$('img',content.document);
但是仍然无效,
是否有人遇到过这个问题?
我使用下面的 example.xul
:
<?xml version =1.0?>
< overlay id =examplexmlns =http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul>
< head>< / head>
< script type =application / x-javascriptsrc =jquery.js>< / script>
< script type =application / x-javascriptsrc =example.js>< / script>
< / overlay>
这里是 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){
//检查网站
if(!doc.location.href.match(/ ^ http:\ / \ / * \。)?stackoverflow\.com(\ /.*)?$/ i))
return;
//检查是否已经加载
if( doc.getElementById(plugin-example))return;
//安装
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>');
};
//绑定插件
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);
})();
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>
but the $() function is not recognized in the xul file neither do the jQuery().
I googled about the problem and found some solutions but no one did work with me: http://gluei.com/blog/view/using-jquery-inside-your-firefox-extension http://forums.mozillazine.org/viewtopic.php?f=19&t=989465
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);
but still not working, does any one came across this problem before?
I use the following example.xul
:
<?xml version="1.0"?>
<overlay id="example" xmlns="http://www.mozilla.org/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>
And here is an example.js
(function() {
jQuery.noConflict();
$ = function(selector,context) {
return new jQuery.fn.init(selector,context||example.doc);
};
$.fn = $.prototype = jQuery.fn;
example = new function(){};
example.log = function() {
Firebug.Console.logFormatted(arguments,null,"log");
};
example.run = function(doc,aEvent) {
// Check for website
if (!doc.location.href.match(/^http:\/\/(.*\.)?stackoverflow\.com(\/.*)?$/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);
})();
