<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.

畢竟是MSDN，幾乎是要什么有什么有什么啊．經(jīng)過這次打擊后，總結(jié)出經(jīng)驗(yàn)：不會(huì)的東西不要很快就去問別人，靠自己摸索其實(shí)一樣能找出另你滿意的答案．
不過還有一點(diǎn)很重要的是要學(xué)會(huì)查MSDN，輸入的關(guān)鍵字要命中要害，可以說應(yīng)該要一針見血．還有實(shí)在找不出的時(shí)候，就去查看目錄，一級(jí)一級(jí)的往下找，總能找到你想要的．
