如何将下拉菜单添加到 Firefox 插件 sdk 驱动的插件工具栏按钮? [英] How to add a dropdown menu to a firefox addon sdk powered addon toolbar button?

问题描述

我使用 https://github.com/erikvold/toolbarbutton-jplib/包以将工具栏按钮从 addon-sdk 插件添加到 firefox 导航栏.是否可以向此按钮添加下拉菜单(据我所知没有简单的方法)?

I use the https://github.com/erikvold/toolbarbutton-jplib/ package to add a toolbar button from an addon-sdk addon to the firefox navigation bar. Is it possible to add a drop down menu to this button (as I understand there are no easy ways)?

推荐答案

这段代码需要多几行才能真正起作用:

This code requires a few more lines to actually work:

var delegate = {
onTrack: function(window) {

    if(window.location != "chrome://browser/content/browser.xul") {
        // console.log("=> win location false");
        return;
    }

    var document = window.document;
    var navBar = document.getElementById('nav-bar');

    var btn = document.createElement('toolbarbutton');
    btn.setAttribute('id', 'button');
    btn.setAttribute('type', 'menu-button');
    btn.setAttribute('class', 'toolbarbutton-1');
    btn.setAttribute('image', 'http://www.facebook.com/favicon.ico');

    btn.addEventListener('command', function() {
            console.log("this=" + this.id);
            // your callback code here
        }
        , false);

    var menupopup = document.createElement('menupopup');
    menupopup.setAttribute('id', 'menupopup');
    menupopup.addEventListener('command', function(event) {
            // TODO your callback
        }
        , false);

    //menu items
    var menuitem1 = document.createElement('menuitem');
    menuitem1.setAttribute('id', 'menuitem1');
    menuitem1.setAttribute('label', 'Menu item1');
    menuitem1.setAttribute('class', 'menuitem-iconic');
    menuitem1.addEventListener('command', function(event) {
            // CODE
        }
        , false);

    menupopup.appendChild(menuitem1);
    btn.appendChild(menupopup);
    navBar.appendChild(btn);

    console.log("window tracked");

    }
};

//let utils = require('api-utils/window-utils');
let utils = require('sdk/deprecated/window-utils'); // for new style sdk
utils.WindowTracker(delegate);
