消除window.close()的提示窗口
Window.close()这句脚本是用来关闭当前窗口，如果是在window.open的窗口中执行Window.close()，将会很顺利 地将窗口关闭，但如果是在一非window.open打开的窗口中执行Window.close()，将会弹出一个提示窗口，如下：
要在程序中消除这个提示框也很简单，不过在IE6和IE7稍有不同
1. IE6
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">

<script type="text/javascript">
function closeWin()
{
window.opener=null;
window.close();
}
</script>
</head>
<body>
<form id="form2" runat="server">
<div>
<input id="btnClose" type="button" value="close" onclick="closeWin()"/>
</div>
</form>
</body>
</html>
2.IE7
