javascript - 将附加 SDK 面板链接到工具栏按钮

Question

附加 SDK 将面板附加到小部件，如所示 here 。我想通过工具栏按钮使用附加 SDK 来实现相同的效果。

我使用的工具栏按钮是 type 菜单按钮，这意味着左侧是一个图标并且有一个oncommand监听器。右侧是一个下拉箭头，单击时会显示其内容。以下是使用附加 SDK 创建此类按钮的代码:

const doc = require('sdk/window/utils').getMostRecentBrowserWindow().document;

var navBar = doc.getElementById('nav-bar')
var btn = doc.createElement('toolbarbutton');
btn.setAttribute('id', 'hylytit');
btn.setAttribute('type', 'menu-button');
btn.setAttribute('class', 'toolbarbutton-1');
btn.setAttribute('image', data.url('resources/hylyt_off.png'));
btn.setAttribute('orient', 'horizontal');
btn.setAttribute('label', 'Hylyt.it');
btn.addEventListener('command', function(event) {
  if (event.button===0) btnClick();
  console.log(TAG+'button clicked');
}, false);
var panel = doc.createElement('panel');
panel.setAttribute('id', 'search-panel');
panel.addEventListener('command', function(event) {
    console.log(TAG+'dropdown clicked');
}, false);
var label = doc.createElement('label');
label.setAttribute('control', 'name');
label.setAttribute('value', 'Article List');
var textbox = doc.createElement('textbox');
textbox.setAttribute('id', 'name');
panel.appendChild(label);
panel.appendChild(textbox);
btn.appendChild(panel);
navBar.appendChild(btn);

上面的面板不是附加SDK面板，它是XUL panel并且受到严重限制，因为它不能使用 CSS 进行样式设置。最重要的是，尽管 btn 的 onCommand 按预期触发，但面板的 onCommand 监听器永远不会触发。当我单击下拉按钮时，XUL 面板会自行显示(只要它有子项)，但由于我无法访问其单击处理程序，因此我不能仅在单击时创建附加 SDK 面板。

所以我的问题是这样的。有没有办法访问工具栏按钮的菜单部分的点击处理程序，或者有没有办法将附加 SDK 面板附加为工具栏按钮的子项？

Thanks for pointing me in the direction of arrow panels. Is there a way to place an HTML file in one rather than having to dynamically create XUL elements? The effect I'm trying to achieve is similar to the Pocket extension, which does one thing when the button part is clicked and another when the arrow is clicked. – willlma 7 hours ago

你有 900+ 代表，你应该更清楚。创建另一个问题主题而不是在评论中询问如何做不同的事情是常识，尤其是在解决方案被接受之后。

尽管如此，这就是您为实现 Pocket 工具栏按钮效果所做的事情。基于上面贡献者提供的代码。问另一个问题，我会将其移至此处，您可以在那里接受我的解决方案。
