我很好奇。我可以向BrowserPalette添加一个按钮,然后使用此代码将其移动到工具栏,可以将粘贴复制到暂存器并运行。
var doc = document;
var win = doc.defaultView;
var toolbox = doc.querySelector('#navigator-toolbox');
var buttonId = 'bpMyBtn';
var button = doc.getElementById(buttonId);
if (!button) {
button = doc.createElementNS('http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'toolbarbutton');
button.setAttribute('id', buttonId);
button.setAttribute('label', 'My Button');
button.setAttribute('tooltiptext', 'My buttons tool tip if you want one');
button.setAttribute('class', 'toolbarbutton-1 chromeclass-toolbar-additional');
button.style.listStyleImage = 'url("https://gist.githubusercontent.com/Noitidart/9266173/raw/06464af2965cb5968248b764b4669da1287730f3/my-urlbar-icon-image.png")';
button.addEventListener('command', function() {
alert('you clicked my button')
}, false);
toolbox.palette.appendChild(button);
}
var targetToolbar = doc.querySelector('#nav-bar');
//move button into last postion in targetToolbar
targetToolbar.insertItem(buttonId); //if you want it in first position in targetToolbar do: targetToolbar.insertItem(buttonId, navBar.firstChild);
targetToolbar.setAttribute('currentset', targetToolbar.currentSet);
doc.persist(targetToolbar.id, 'currentset');
然而doc.persist
无效,一旦我重新启动浏览器按钮就消失了。是否可以使用persist在第一次启动插件时添加一个按钮并使其保持不变?
这也导致了如何删除按钮并坚持下去的问题? (即卸载时从调色板中删除,另一个即:从工具栏中删除,换句话说就是将其发送回调色板并坚持下去)
我从这里得到了持久代码: https://developer.mozilla.org/en-US/Add-ons/Code_snippets/Toolbar#Adding_button_by_default

我正在使用最初在Erik Vold的贡献之一中找到的库,这是我对bootstrap开发的主要知识来源。它的工作原理很奇妙:

(function(global) {
let positions = {};
/*
* Assigns position that will be used by `restorePosition`
* if the button is not found on any toolbar's current set.
* If `beforeID` is null, or no such item is found on the toolbar,

*/
global.setDefaultPosition = function(buttonID, toolbarID, beforeID) {
positions[buttonID] = [toolbarID, beforeID];
};
/*
* Restores the button's saved position.
* @param {XULDocument} doc XUL window document.
* @param {XULElement} button button element.
*/
global.restorePosition = function(doc, button, toolbox) {
function $(sel, all)
doc[all ? "querySelectorAll" : "getElementById"](sel);
($(toolbox) || $("header-view-toolbox") || $("navigator-toolbox") || $("mail-toolbox")).palette.appendChild(button);
let toolbar, currentset, idx,
toolbars = $("toolbar", true);
for (let i = 0; i < toolbars.length; ++i) {
let tb = toolbars[i];
currentset = tb.getAttribute("currentset").split(","),
idx = currentset.indexOf(button.id);
if (idx != -1) {
toolbar = tb;
break;
}
}
// saved position not found, using the default one, if any
if (!toolbar && (button.id in positions)) {
let [tbID, beforeID] = positions[button.id];
toolbar = $(tbID);
[currentset, idx] = persist(doc, toolbar, button.id, beforeID);
}
if (toolbar) {
if (idx != -1) {
// inserting the button before the first item in `currentset`
// after `idx` that is present in the document
for (let i = idx + 1; i < currentset.length; ++i) {
let before = $(currentset[i]);
if (before) {
toolbar.insertItem(button.id, before);
return;
}
}
}
toolbar.insertItem(button.id);
}
};
function persist(document, toolbar, buttonID, beforeID) {
let currentset = toolbar.getAttribute("currentset").split(","),
idx = (beforeID && currentset.indexOf(beforeID)) || -1;
if (idx != -1) {
currentset.splice(idx, 0, buttonID);
} else {
currentset.push(buttonID);
}
toolbar.setAttribute("currentset", currentset.join(","));
document.persist(toolbar.id, "currentset");
return [currentset, idx];
}
})(this);
然后在安装功能中使用:
setDefaultPosition("my_button_id", "navigator-toolbox", null);
(为了便于测试,您可以将其添加到启动功能中:
if (reason == ADDON_INSTALL)
{
setDefaultPosition("my_button_id", "navigator-toolbox", null);
}
最后添加按钮本身在你的窗口加载函数中使用这样的东西:
let toolbarbutton = document.createElement("toolbarbutton"),
toolbarbutton.id = "my_button_id";
toolbarbutton.setAttribute("label", "My toolbar button");
restorePosition(document, toolbarbutton, "navigator-toolbox");
unload(function()
{
toolbarbutton.parentNode.removeChild(toolbarbutton);
});
(unload()又是Erik Vold的另一个库函数)
