AJAX使用cookie传值例子:<br>
<form name=myform>
name:<input id=name value="变量名甚至可以是中文" size=20><br>
value:<input type=text size=20 id=val value=这里><br>
<input onclick="getXML()" type="button" value="送出数据">
<input onclick="if(xh && xh.responseText) {alert(xh.responseText);}" type="button" value="显示返回结果"><br>
<div id=m bgcolor=blue>在此显示状态</div>
<input type=button onclick="alert(document.cookie)" value=显示本地COOKIE>
</form>
服务器端代码 a.php
<?
header("Content-type: text/html;charset=GB2312");
echo "以下是您送出的所有COOKIE变量及其值n";
print_r($_COOKIE);
?>
