<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>select加链接实现选中跳转</title>
</head>
<body>
<SCRIPT language=javascript>
<!--
// open the related site windows
function mbar(sobj) {
var docurl =sobj.options[sobj.selectedIndex].value;
if (docurl != "") {
open(docurl,'_blank');
sobj.selectedIndex=0;
sobj.blur();
}
}
//-->
</SCRIPT>
<Select onchange=mbar(this) name="select">
<OPTION selected>=== 合作伙伴 ===</OPTION>
<OPTION value="http://www.baidu.com">百度</OPTION>
<OPTION value="http://www.163.com">网易</OPTION>
<OPTION value="http://www.flash8.net/">闪吧</OPTION>
</Select>

<select name="pageselect" onchange="self.location.href=options[selectedIndex].value" > <OPTION value="http://www.baidu.com">百度</OPTION> <OPTION value="http://www.163.com">网易</OPTION> </select>
