在 Firefox Bootstrapped Addons 中,上下文菜单项必须手动插入/删除、启用/禁用和隐藏/取消隐藏。
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),以便可以将组作为一个元素处理,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>
我试着把它们放进<menu> ... </menu>
去,但那缩进了menuitem
更新:
我注意到 Flashgot 覆盖有一个混合的menuitem
分组menupopup
<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。第二个是在插入menuitem
之后<menu class="menu-iconic>
