如例:index.html
<script src="js_admin.js"> </script>
<INPUT onchange="javascript:film_nametest()" name=t1> ccc.php <script src="js_admin.js"> </script>
<?php
switch ($act) {
case "on":
echo " <div id=responseT>我爱您中国$act </div>";
break;
}
?>
js_admin.js
function film_nametest(){
var xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
xmlhttp.open("POST","http://127.0.0.1/ccc.php?act=on",true);
xmlhttp.send();
function doHttpReadyStateChange() {
if (xmlhttp.readyState == 4) alert(xmlhttp.responseTEXT);
}
alert(innerHTML=responseT.innerHTML)
} 怎样在才能在index.html弹出ccc.php?act=on 文件中的"中国我爱你"
