一个ajax的问题
ajax.php
PHP code

<script>
    function GetXmlHttpObject()
    {
        var XMLHttp=null;
        try
        {
            XMLHttp=new XMLHttpRequest();
        }
        catch(e)
        {
            try
            {
                XMLHttp=new ActiveXObject("Msxml2.XMLHTTP");
            }
            catch(e)
            {
                XMLHttp=new ActiveXObject("Microsoft.XMLHTTP");
            }
        }
        return XMLHttp;
    }
    
    
    function submit_form(tag)
    {
        XMLHttp=GetXmlHttpObject();
        var aurl="deal_ajax.php?tag="+tag+"&url="+document.getElementById("url").value+"";
        XMLHttp.open("GET",aurl,true);
        XMLHttp.send(null);
        XMLHttp.onreadystatechange=function()
        {
            if(XMLHttp.readyState==4&&XMLHttp.status==200)
            {
                document.getElementById("status").innerHTML=XMLHttp.responseText;
            }
        }
    }
</script>
</head>

<body>
<div align="center" style="text-align:center">
<form action="" method="post">
<table width="900" border="1">
  <tr>
    <td>url</td>
    <td><input name="url" type="text"  style="width:400px" id="url"/></td>
  </tr>
  <tr>
    <td>message</td>
    <td><textarea name="message" cols="" rows="" id="message"></textarea></td>
  </tr>
  <tr>
    <td><input name="save" type="submit" value="保存"  id="save" onclick="submit_form('later')"/></td>
    <td><input name="fabu" type="submit" value="发布"  id="fabu" onclick=""/></td>
  </tr>
</table>

</form>
<div id="status"></div>
</div>
</body>
</html>


deal_ajax.php
PHP code

<?php
echo "#######@".$_REQUEST['url'];
?>



点击“保存”按钮可以异步提交到deal_ajax.php,但是马上就走form的action了!!!!用post也是

------解决方案--------------------
<td><input name="save" type="button" value="保存" id="save" onclick="submit_form('later')"/></td>
<td><input name="fabu" type="button" value="发布" id="fabu" onclick=""/></td>
------解决方案--------------------
type="submit" 

改成
type="button"
------解决方案--------------------
onclick="submit_form('later');return false"
------解决方案--------------------
PHP code

echo "<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />" .
        "<script type='text/javascript' language='javascript'>".
        "if(confirm('ok')){" .
        "    window.location.href='{$href}';" .
        "} else
