[תÌû]Attribute contextMenu Attribute contextMenu Synopsis: readonly dom::Document contextMenu XML document that represents SVG Viewer's context menu. Any change to this document will be reflected on the context menu (when it pops up). The document's root element must be a "menu" element. The following elements are allowed in menu: header   menu header; most systems ignore header text content of this element will be visible on the menu on the systems that support menu headers   item   an item in the menu text content of this element will be visible as item's text; character "&" designates hot key.   separator   separator bar   menu   submenu; some systems can flatten submenus   item element can have following attributes (note that xlink:href attribute must be in XLink namespace, use only setAttributeNS to set it): action   system action that this item will cause if activated   onactivate   script that gets executed when this item is activated   xlink:href   follow the specified URL   target   used together with xlink:href   checked   can be either "yes" or "now", will cause a checkmark be drawn next to this item   display   can be either "inline" or "none"; if "none" this item is ignored   enabled   can be either "yes" or "no"; if "no" this item is visible, but cannot be selected   Supported system actions are listed here: ZoomIn ZoomOut OriginalView Quality Pause Mute Find FindAgain Copy CopySVG ViewSVG ViewSource SaveAs SaveOriginalAs SaveSnapshotAs Help About It is strongly recommended to have 'About' action in the menu. Menus without 'About' action may get ignored by the viewer. -------------------------------------------------------------------------------- A (nearly-)complete, fairly generic example of this -including activation of the 'checked,' 'display,' and 'enabled' options- can be seen at http://www.svg-whiz.com/images/customcontextmenu.svg. -------------------------------------------------------------------------------- Implementation Note: It is not possible in ASV3 to access the built-in functions of the context menu (such as "CopySVG" or "SaveAs") through script. This is a security feature. -------------------------------------------------------------------------------- Disabling the Context Menu To prevent the menu from appearing at all, you can use some variation of the following code: <svg onmousedown="evt.preventDefault()" onmouseup="evt.preventDefault()">    ... </svg> This can be useful when you want to provide your own context menu, or when you want the right-click to have another action.    Êղؠ  ·ÖÏí   ¶¥(0)
