JQuery中select標籤綁定的onchange事件然後彈出選擇的值並實現跳轉和傳參

<script src="jquery.min.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
$(document).ready(function(){  
$(&#39;#mySelect&#39;).change(function(){  
alert($(this).children(&#39;option:selected&#39;).val());  
var p1=$(this).children(&#39;option:selected&#39;).val();//这就是selected的值  
var p2=$(&#39;#param2&#39;).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="1">one</option>
<option value="2" selected="selected">two</option>
<option value="3">three</option>
</select>
<input type="text" value="ooo" name="param2" id="param2"/>

$("#ddlregtype").find("option:selected").text();

$("#ddlregtype ").val();

$("#ddlregtype ").get(0).selectedindex;

$("#mySelect").val(); //获取选中记录的value值
$("#mySelect option:selected").text(); //获取选中记录的text值

var obj = document.getElementById("mySelect");  
obj.add(new Option("4","4"));

var obj = document.getElementById("mySelect");  
obj.options.length = 0;

var obj = document.getElementById("mySelect");  
var index = obj.selectedIndex;  
obj.options.remove(index);

var obj = document.getElementById("mySelect");  
var index = obj.selectedIndex;  
obj.options[index] = new Option("three",3); //更改对应的值
obj.options[index].selected = true; //保持选中状态

var obj = document.getElementById("mySelect");  
obj.parentNode.removeChild(obj); //移除当前对象

$("#mySelect").change(function(){  
//添加所需要执行的操作代码
})
