我尝试使用SDK进行firefox扩展。 (如果我能避免XUL,我很高兴)
但我需要动态更改工具栏图像。
我的lib / main.js(背景页面)是:
var tbb = require("toolbarbutton").ToolbarButton({
id: "My-button",
label: "My menu",
image: Data.url('off.png'),
onCommand: function(){
Tabs.open(Data.url("signin.html"));
}
});
tbb.setIcon({image:Data.url('on.png')});
console.log(tbb.image);
tbb.moveTo({
toolbarID: "nav-bar",
forceMove: false // only move once
});
tbb.image是正确的,但按钮没有刷新。
我尝试更改packages / toolbarbutton -jplib / lib / toolbarbutton.js
function setIcon(aOptions) {
options.image = aOptions.image || aOptions.url;
getToolbarButtons(function(tbb) {
tbb.image = options.image;
tbb.setAttribute("image", options.image); // added line
}, options.id);
return options.image;
}
但它似乎没有刷新...... erik vold lib是否足以满足这种需求?

我遇到了同样的问题所以我只是使用本教程编写了自己的代码: http://kendsnyder.com/posts/firefox-extensions-add-button-to-nav-bar
试试这个,我重写了我的代码以满足您的需求:
var btn = null;
var btnId = 'My-button';
var btnLabel = 'My menu';
var btnIconOn = 'on.png';
var btnIconOff = 'off.png';
var {Cc, Ci} = require('chrome');
var self = require("sdk/self");
var mediator = Cc['@mozilla.org/appshell/window-mediator;1'].getService(Ci.nsIWindowMediator);
// exports.main is called when extension is installed or re-enabled
exports.main = function(options, callbacks) {
btn = addToolbarButton();
// do other stuff
};
// exports.onUnload is called when Firefox starts and when the extension is disabled or uninstalled
exports.onUnload = function(reason) {
removeToolbarButton();
// do other stuff
};
// add our button
function addToolbarButton() {
// this document is an XUL document
var document = mediator.getMostRecentWindow('navigator:browser').document;
var navBar = document.getElementById('nav-bar');
if (!navBar) {
return;
}
var btn = document.createElement('toolbarbutton');
btn.setAttribute('id', btnId);
btn.setAttribute('type', 'button');
// the toolbarbutton-1 class makes it look like a traditional button
btn.setAttribute('class', 'toolbarbutton-1');
// the data.url is relative to the data folder
btn.setAttribute('image', self.data.url(btnIconOff));
btn.setAttribute('orient', 'horizontal');
// this text will be shown when the toolbar is set to text or text and iconss
btn.setAttribute('label', btnLabel);
navBar.appendChild(btn);
return btn;
}
function removeToolbarButton() {
// this document is an XUL document
var document = mediator.getMostRecentWindow('navigator:browser').document;
var navBar = document.getElementById('nav-bar');
var btn = document.getElementById(btnId);
if (navBar && btn) {
navBar.removeChild(btn);
}
}
btn.addEventListener('click', function() {
Tabs.open(Data.url("signin.html"));
}, false);
tbb.setIcon({image:self.data.url(btnIconOn)});
