exactly 6 or 6 at max? ... probably the best way would be a regExp, but there are a lot of possibilities to achieve that task ... you could even loop through the characters of the string for example etc. ...

??? here is an example to test a string s for containing exactly 6 numbers ... you would just need to adapt that to your needs ... since you didn't clearly specify your requirement:

var s = '13245a';

function validate(s) {
    var re = /\d{6,6}/;

    return re.test(s);
}

alert(validate(s));

to your following code:

<html>
<head>
<script type="text/javascript">
var s = '12345a';
function validate(s)
{
var re = /\d{6,6}/;
return re.test(s);
}
alert(validate(s));
</script>
</head>
<body>
<form action=" " onsubmit="return validate()">
<table>
<tr><td>emp id</td><td><input type="text" id=" "></td></tr>
<tr><td><input type="submit" value="submit"></td></tr>
</table>
</form>
</body>

you just copied and pasted the above example to a html-page. you need to adapt that, so that the value of the input node is retrieved and validated ... currently you call the validate() method without an argument. you should even drop the alert and the variable declaration for s.
