让Firefox在启动时运行XUL类型脚本 [英] Get Firefox to run XUL type script on startup
问题描述
使用Firefox 17.0.1，我使用名为 KeyConfig 20110522 的附加组件来设置一些新的热键，并设置 acceltext menuitems 用于我的新密钥以及附加组件，而这些附加组件不需要这么做。
I <当Firefox启动时， 菜单项的 acceltext 被设为 >，但目前我只是使用热键通过 KeyConfig 对UI执行以下代码：
document.getElementById（tabmix-menu）
.setAttribute（acceltext，Alt + Ctrl + Shift + T）;
//更多相同...
我需要一些初学者的提示：
-
如何以与执行控制台的HTML页面相同的方式对UI执行任意代码？
-
有没有一种偷偷摸摸的方法可以在浏览器启动时执行一堆代码，而无需深入研究XUL开发？ b $ b
-
有没有办法跟踪对UI执行的命令，这样我就可以使用命令调用，而不是在使用触发器的时候使用触发器：
-
引导式扩展： https://developer.mozilla.org/zh-CN/docs/Extensions/Bootstrapped_extensions
- 很好的例子： http：//blog.fpmurphy。 com / 2011/02 / firefox-4-restartless-add-ons.html 引导程序接口可以非常简单的实现：
$
document.getElementById（tabmix-menu）。click（）; 这种类型的低级黑客攻击的任何其他提示也将受到欢迎。
>你可以从一个插件对Firefox UI执行任意代码，但正如你所说，做所有的XUL相关的东西有点无聊： - ）
输入Bootstrapped 扩展！
第1部分：
Bootstrapped（或重新启动）扩展只需要一个install.rdf文件来标识插件，一个bootstrap.js文件来实现引导程序接口。
$ b $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ b函数关闭（数据，原因）{}
函数启动（数据，原因）{/ *您的任意代码在这里！ * /}
通过将 install.rdf 和 bootstrap.js 添加到新zip文件的顶层，并将zip文件扩展名重命名为.xpi。 第二部分：
您的代码有特权，可以使用任何Mozilla平台API。但是，有一个时间问题。执行启动功能的那一刻是没有Chrome窗口对象存在的时间！
如果您的代码对您有重要意义Chrome窗口，我们需要等待它出现：
//有用的服务。
Cu.import（resource：//gre/modules/Services.jsm）;
var loader = Cc [@ mozilla.org/moz/jssubscript-loader;1]
.getService（Ci.mozIJSSubScriptLoader）;
var wmSvc = Cc [@ mozilla.org/appshell/window-mediator;1]
.getService（Ci.nsIWindowMediator）;
var logSvc = Cc [@ mozilla.org/consoleservice;1]
.getService（Ci.nsIConsoleService）;
//获取第一个gBrowser
var done_startup = 0;
var windowListener;
函数do_startup（win）{
if（done_startup）return;
done_startup = 1;
wmSvc.removeListener（windowListener）;
var browserEnum = wmSvc.getEnumerator（navigator：browser）;
var browserWin = browserEnum.getNext（）;
var tabbrowser = browserWin.gBrowser;
/ *您的代码在这里！ * /
}
//窗口侦听器实现
windowListener = {
onWindowTitleChange：function（aWindow，aTitle）{}，
onCloseWindow：function aWindow）{}，
onOpenWindow：function（aWindow）{
var win = aWindow.QueryInterface（Ci.nsIInterfaceRequestor）
.getInterface（Ci.nsIDOMWindowInternal || Ci.nsIDOMWindow）;
win.addEventListener（load，function（aEvent）{
win.removeEventListener（load，arguments.callee，false）;
if（aEvent.originalTarget.nodeName！= #document）return;
do_startup（）;
}
};
// CODE ENTRY POINT（把这个放在bootstrapstartup函数中）
wmSvc.addListener（windowListener）;
With Firefox 17.0.1 I am using an add-on called KeyConfig 20110522 to set some new hot keys and also set the acceltext of menuitems for my new keys as well as for add-ons that do not bother to do so.
I want the acceltext of the menuitems to be set when Firefox starts, but currently I am just using a hot key to execute the following code against the UI via KeyConfig:
document.getElementById("tabmix-menu")
.setAttribute("acceltext","Alt+Ctrl+Shift+T");
// more of the same...
I need a couple of beginners tips:
How can I execute arbitrary code against the UI in the same way as I execute against an HTML page via the console?
Is there a sneaky way to get a clump of code to execute on browser start-up without delving into XUL development?
Is there a way to trace commands executed against the UI so I can get at command calls instead of using triggers when I set my hot keys like so:
document.getElementById("tabmix-menu").click();
Any other tips on this type of low-level hacking would also be welcome.
You can execute arbitrary code against the Firefox UI from an addon, but as you say, doing all the XUL related stuff is a bit boring :-)
Enter "Bootstrapped" extensions!
Part 1:
A "Bootstrapped" (or re-startless) extension needs only an install.rdf file to identify the addon, and a bootstrap.js file to implement the bootstrap interface.
Bootstrapped Extension: https://developer.mozilla.org/en-US/docs/Extensions/Bootstrapped_extensions
Good example: http://blog.fpmurphy.com/2011/02/firefox-4-restartless-add-ons.html
The bootstrap interface can be implemented very simply:
function install() {}
function uninstall() {}
function shutdown(data, reason) {}
function startup(data, reason) { /* YOUR ARBITRARY CODE HERE! */ }
You compile the extension by putting install.rdf and bootstrap.js into the top-level of a new zip file, and rename the zip file extension to .xpi.
Part 2:
Your code is privileged and can use any of the Mozilla platform APIs. There is however an issue of timing. The moment-in-time at which the "startup" function is executed is one at which no Chrome window objects exist yet!
If it's important for your code that you have a Chrome Window, we need to wait for it to appear:
// useful services.
Cu.import("resource://gre/modules/Services.jsm");
var loader = Cc["@mozilla.org/moz/jssubscript-loader;1"]
.getService(Ci.mozIJSSubScriptLoader);
var wmSvc = Cc["@mozilla.org/appshell/window-mediator;1"]
.getService(Ci.nsIWindowMediator);
var logSvc = Cc["@mozilla.org/consoleservice;1"]
.getService(Ci.nsIConsoleService);
// get the first gBrowser
var done_startup = 0;
var windowListener;
function do_startup(win) {
if (done_startup) return;
done_startup = 1;
wmSvc.removeListener(windowListener);
var browserEnum = wmSvc.getEnumerator("navigator:browser");
var browserWin = browserEnum.getNext();
var tabbrowser = browserWin.gBrowser;
/* your code goes here! */
}
// window listener implementation
windowListener = {
onWindowTitleChange: function(aWindow, aTitle) {},
onCloseWindow: function(aWindow) {},
onOpenWindow: function(aWindow) {
var win = aWindow.QueryInterface(Ci.nsIInterfaceRequestor)
.getInterface(Ci.nsIDOMWindowInternal || Ci.nsIDOMWindow);
win.addEventListener("load", function(aEvent) {
win.removeEventListener("load", arguments.callee, false);
if (aEvent.originalTarget.nodeName != "#document") return;
do_startup();
}
};
// CODE ENTRY POINT (put this in bootstrap "startup" function)
wmSvc.addListener(windowListener);
