javascript setTimeout错误

我正在尝试制作一个每5秒移动一次的进度条.这是我的代码:

function Progress(runner, validlinks)
{
    if (runner <= validlinks)
    {
        var myString = document.getElementById('links').value;
        var mySplit = myString.split("\n");
        var ValidLinksCount = 0;

        for(i = 0; i < mySplit.length; i++)
        {
            if (mySplit[i].search("who") != -1)
                ValidLinksCount++;
                ValidLinksCount++;
            else if (mySplit[i].search("we") != -1)
                ValidLinksCount++;
        }
        var jump = Math.ceil(100 / ValidLinksCount);
        runner++;
        document.getElementById("progressDiv").style.width = parseInt(document.getElementById("progressDiv").style.width) + jump + "%";
        window.setTimeout(Progress(runner,ValidLinksCount), 5000);
    }
}

我在按钮提交上称它为:

<input type="submit" name="submit" disabled="true" onclick="Progress(0,0);" value="check" />

它只是运行,并且不会等到下一次运行5秒,为什么？谢谢.

ajax和php不能一起工作

这是整个HTML代码:

<title></title>
<script type="text/javascript">
function send()
    {
        var xmlhttp;
         if (window.XMLHttpRequest)
           {// code for IE7+, Firefox, Chrome, Opera, Safari
           xmlhttp=new XMLHttpRequest();
           }
         else
           {// code for IE6, IE5
           xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
           }

        xmlhttp.onreadystatechange=function()
           {
           if (xmlhttp.readyState==4 && xmlhttp.status==200)
             {
                alert(xmlhttp.responseText);
             }
           }

        xmlhttp.open("POST","add.php",true);
        xmlhttp.send('subject=' + document.getElementById("subject").value);
    }
</script>
</head>
<body>
<form name="main" method="post" action="add.php">
<div align="center">    
<table border="1" frame="hsides" rules="rows" cellpadding="5" cellspacing="0" width="50%" align="center">
    <tr>
        <td width="20%">
            subject: 
        </td>
        <td width="80%" align="right">
            <input type="text" size="80" maxlength="80" name="subject" id="subject" />
        </td>
