</head> 

<body> 
<p> 
<script language="javascript"> 
function delcfm() { 
if (!confirm("确认要删除？")) { 
window.event.returnValue = false; 
} 
} 
</script> 
<a href="http://www.lanrentuku.com/" onClick="delcfm()">删除</a></p> 
<p>代码说明：单击删除的超链接后将执行delcfm()函数，在对话框中，如果点击“确定”，函数将返回true值，就将页面转到<a>标签中的链接页面执行删除的页面；如果点击“取消”，函数将返回false值，<a>标签将不转到执行删除的页面。</p>
