AJAX使用cookie傳值例子:<br>
<form name=myform>
name:<input id=name value="變數名甚至可以是中文" size=20><br>
value:<input type=text size=20 id=val value=這裡><br>
<input onclick="getXML()" type="button" value="送出資料">
<input onclick="if(xh && xh.responseText) {alert(xh.responseText);}" type="button" value="顯示返回結果"><br>
<div id=m bgcolor=blue>在此顯示狀態</div>
<input type=button onclick="alert(document.cookie)" value=顯示本地COOKIE>
</form>
伺服器端代碼 a.php 複製代碼 代碼如下:<?
header("Content-type: text/html;charset=GB2312");
echo "以下是您送出的所有COOKIE變數及其值\n";
print_r($_COOKIE);
?>
