<H1>oncontextmenu Event Sample</H1>
<P>This sample shows how to use the <B>oncontextmenu</B> event handler, available in Microsoft® Internet Explorer 5 and later, to display both standard and custom context menus and prevent context menus from displaying. Experiment with each of the following boxes to see how you can apply different methods either to display or to inhibit context menus. Each box provides instructions for you to follow.
</P>
<SPAN class="clickableSpan">
1. The default context menu always displays when you right-click in this box.
<b><br>Code: </b>
//no code necessary
</SPAN><br><br>
<SPAN class="clickableSpan" oncontextmenu="return event.ctrlKey">
2. The default context menu displays only if you right-click in this box while holding down the Ctrl key. This is useful for developing and debugging purposes.
<b><br>Code: </b>
oncontextmenu="return event.ctrlKey"
</SPAN><br><br>
<SPAN class="clickableSpan" oncontextmenu="return false">
3. A context menu never displays when you right-click in this box.
<b><br>Code: </b>
oncontextmenu="return false"
</SPAN><br><br>
<SPAN class="clickableSpan" oncontextmenu="displayMenu();return false">
4. A custom context menu displays when you right-click in this box.
<b><br>Code: </b>
oncontextmenu="showMenu();return false;"
</SPAN><br><br>
<SPAN class="clickableSpan" oncontextmenu="if (!event.ctrlKey){displayMenu();return false;}">
5. A custom menu displays when you right-click in this box. If you right-click while holding down the Ctrl key, the default context menu displays.
<b><br>Code: </b>
oncontextmenu="if (!event.ctrlKey){displayMenu();return false;}"

毕竟是MSDN，几乎是要什么有什么有什么啊．经过这次打击后，总结出经验：不会的东西不要很快就去问别人，靠自己摸索其实一样能找出另你满意的答案．
不过还有一点很重要的是要学会查MSDN，输入的关键字要命中要害，可以说应该要一针见血．还有实在找不出的时候，就去查看目录，一级一级的往下找，总能找到你想要的．
