$(document).ready(function(){ 
$(\'#mySelect\').change(function(){ 
alert($(this).children(\'option:selected\').val()); 
var p1=$(this).children(\'option:selected\').val();//这就是selected的值 
var p2=$(\'#param2\').val();//获取本页面其他标签的值 
window.location.href="xx.php?param1="+p1+"¶m2="+p2+"";//页面跳转并传参 
}) 
}) 
</script> 

<select id="mySelect">

<option value="2" selected="selected">two</option> 
<option value="3">three</option> 
</select> 
<input type="text" value="ooo" name="param2" id="param2"/>
