将上下文菜单项组合在一起

在Firefox Bootstrapped Addons中,必须手动插入/删除,启用/禁用以及隐藏/取消隐藏上下文菜单项。

我想知道是否可以将它们组合成一个元素(作为该元素的子元素),以便可以将该组处理为一个,即可以删除父节点,从而删除其所有子节点。

例如:

<some parent element for grouping>
    <menuseparator/>
    <menuitem .... />
    <menuitem .... />
    <menuseparator/>
    <menuitem .... />
    <menuseparator/>
</some parent element for grouping>

我尝试将它们放在<menu> ... </menu>内但缩进了menuitem

更新
我注意到Flashgot overlay有一个混合menuitemmenupopup的分组 enter image description here

<popup id="contentAreaContextMenu">  
  <menu id="flashgot-submenu" hidden="true" persist="hidden" label="FlashGot" class="menu-iconic flashgot-icon-lnk" accesskey="&flashgotLink.accesskey;" insertbefore="context-sep-selectall,context-sep-stop,context-sep-copylink" >
      <menupopup>
          <menuseparator id="flashgot-submenu-anchor" hidden="true" />
          <menuitem id="flashgot-menuitem-it" label="&flashgotLink;" accesskey="&flashgotLink.accesskey;" oncommand="gFlashGot.downloadPopupLink()" key="flashgot-link-key" class="menuitem-iconic flashgot-icon-lnk" />
          <menuitem id="flashgot-menuitem-sel" label="&flashgotSel;" accesskey="&flashgotSel.accesskey;" oncommand="gFlashGot.delayCmd('Sel')" key="flashgot-sel-key" class="menuitem-iconic flashgot-icon-sel" />
          <menuitem id="flashgot-menuitem-all" label="&flashgotAll;" accesskey="&flashgotAll.accesskey;" oncommand="gFlashGot.delayCmd('All')" key="flashgot-all-key" class="menuitem-iconic flashgot-icon-all" />
          <menuitem id="flashgot-menuitem-tabs" label="&flashgotTabs;" accesskey="&flashgotTabs.accesskey;" oncommand="gFlashGot.delayCmd('Tabs')" key="flashgot-tabs-key" class="menuitem-iconic flashgot-icon-tabs" />
          <menuitem id="flashgot-menuitem-media" label="&flashgotMedia;" oncommand="gFlashGot.downloadMedia()" key="flashgot-media-key" class="menuitem-iconic flashgot-icon-media" />

          <menuitem id="flashgot-menuitem-buildGallery" label="&flashgotBuildGallery;" class="menuitem-iconic flashgot-icon-buildGallery" oncommand="gFlashGot.buildGallery()" />
              <menu id="flashgot-menu-options" class="menu-iconic flashgot-icon-opts" label="&flashgotOptions;" >
                  <menupopup id="flashgot-menupopup-options" onpopupshowing="gFlashGot.prepareOptsMenu(event.target)">
                  <menuitem id="flashgot-ctx-menuitem-nodms" hidden="true" label="&flashgotNoDMS;" oncommand="gFlashGotService.showDMSReference()" />
                  <menuseparator id="flashgot-ctx-sep-nodms" />
                  <menuitem id="flashgot-ctx-menuitem-opt-autoStart" label="&flashgotAutostart;" type="checkbox" oncommand="gFlashGot.switchOption('autoStart')" />
                  <menuitem id="flashgot-ctx-menuitem-opt-includeImages" label="&includeImages.label;" type="checkbox" oncommand="gFlashGot.switchOption('includeImages')" />
                  <menuitem id="flashgot-ctx-menuitem-opts" label="&flashgotMoreOpts;" oncommand="gFlashGot.openOptionsDialog()" />
                  <menuseparator id="flashgot-ctx-sep-about" />
                  <menuitem id="flashgot-ctx-menuitem-about" label="&flashgotAbout;" oncommand="gFlashGot.openAboutDialog()" />
                  <menuitem id="flashgot-ctx-homepage" label="&flashgotVisitHomepage;" oncommand="gFlashGot.browseHomePage()" />
                  </menupopup>
              </menu>
      </menupopup>
  </menu>  

  <menuseparator id="flashgot-context-separator" hidden="true" insertbefore="context-sep-selectall,context-sep-stop,context-sep-copylink" /> 
  <menuseparator id="flashgot-context-separator2" hidden="true" insertbefore="context-sep-selectall,context-sep-stop,context-sep-copylink" />   
</popup> 

第一个是正常的。第二个是在menuitem

中插入<menu class="menu-iconic>之后

Normal After inserting in a <code><menu class="menu-iconic></code>

我找到了你。将其围绕在<menu><menupopup>

标记中

在此处查看此要点,它会将菜单创建为一个项目: Noitidart / _ff-addon-snippet-CreateMenuWithSubmenuAndAttachToWidget.js

  所以你上面的XUL看起来像这样:

<menu>
    <menupopup>
        <menuseparator/>
        <menuitem .... />
        <menuitem .... />
        <menuseparator/>
        <menuitem .... />
        <menuseparator/>
        <keyset>
            <key id="sample-key1" .... />
            <key id="sample-key2" .... />
            <key id="sample-key3" .... />
        </keyset>
    </menupopup>
</menu>

<menupopup>这样的contentAreaContextMenu期望包含单独的项目(元素),所以即使有一个可以跨平台可靠运行的黑客,它也只是一个黑客攻击,随时都可能破解。所以不,你不能可靠地逻辑地将菜单项组合在一起,这些菜单项仍会作为单独的项目显示在UI中。

此外,您不应将<keyset>等其他无关内容添加到<menupopup>中。同样的道理:可能在任何时候都会破裂。 (虽然<keyset>是一种至少在逻辑上对<key>元素进行分组的方法......)
