1、contextmenu（windows的右键菜单的意思）
<html> <head> <title>ContextMenu Event Example</title> <script type="text/javascript" src="EventUtil.js"></script> </head> <body> <div id="myDiv">Right click or Ctrl+click me to get a custom context menu. Click anywhere else to get the default context menu.</div> <ul id="myMenu" style="position:absolute;visibility:hidden;background-color:silver"> <li><a href="http://www.nczonline.net">Nicholas' site</a></li> <li><a href="http://www.wrox.com">Wrox site</a></li> <li><a href="http://www.yahoo.com">Yahoo!</a></li> </ul> <script type="text/javascript"> EventUtil.addHandler(window, "load", function(event){ var div = document.getElementById("myDiv"); EventUtil.addHandler(div, "contextmenu", function(event){ event = EventUtil.getEvent(event); EventUtil.preventDefault(event); var menu = document.getElementById("myMenu"); menu.style.left = event.clientX + "px"; menu.style.top = event.clientY + "px"; menu.style.visibility = "visible"; }); //设置click事件让菜单隐藏 EventUtil.addHandler(document, "click", function(event){ document.getElementById("myMenu").style.visibility = "hidden"; }); }); </script> </body> </html>
2、window的beforeunload事件
EventUtil.addHandler(window, "beforeunload", function(event){ event = EventUtil.getEvent(event); var message = "I'm really going to miss you if you go."; //针对IE和fiefox event.returnValue = message; //针对safari和Chrome return message; });
