Is it possible to add Context Menu to WebBrowser in WP7?(like IE)
silverlight toolkit Context Menu not support WebBrowser!!!
回答1:
The WebBrowser does not support context menus and doesn't function like other Silverlight controls. Therefore, it's not possible to directly add a ContextMenu. However, there are workarounds possible. One of them is to use the InvokeScript method. You should read this thread. Apparently the code at the bottom of the thread works.
Note: GINternet
is the WebBrowser control's name, so you'll need to change that to yours.
public void AttachContextMenu()
{
try
{
if (GINternet.IsScriptEnabled)
{
GINternet.InvokeScript("execScript", "function FindParentLink(item) \r\n{\r\n\tif (!item.parentNode)\r\n\t\treturn null;\r\n\tif (item.tagName.toLowerCase() == 'a') \r\n\t{\r\n\t\treturn item;\r\n\t} \r\n\telse \r\n\t{\r\n\t\treturn FindParentLink(item.parentNode);\r\n\t}\r\n}\r\n\r\nfunction FindParentImage(item) \r\n{\r\n\tif (!item.parentNode)\r\n\t\treturn null;\r\n\tif (item.tagName.toLowerCase() == 'img') \r\n\t{\r\n\t\treturn item;\r\n\t} \r\n\telse \r\n\t{\r\n\t\treturn FindParentImage(item.parentNode);\r\n\t}\r\n}\r\n\r\nfunction HandleContextMenu() \r\n{\r\n\tvar linkItem = FindParentLink(event.srcElement);\r\n var imageItem = FindParentImage(event.srcElement);\r\n var notifyOutput = '';\r\n if (linkItem != null) if (linkItem.href != null) notifyOutput += linkItem.href;\r\n if (imageItem != null) if (imageItem.src != null) notifyOutput += imageItem.src;\r\n if (notifyOutput != '')\r\n window.external.notify(notifyOutput);\r\n else\r\n\t\twindow.external.notify('NOTLINKIMG');\r\n}");
GINternet.InvokeScript("execScript", "document.oncontextmenu = HandleContextMenu;");
}
}
catch
{
}
}
