Try this.

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<script language="javascript">
function validate(frm){
digitCheck = /^\d+$/;
if(digitCheck.test(frm.textBox.value)){
alert("contains only numbers")
} else {
alert("contains other characters")
}

return digitCheck.test(frm.textBox.value)
}
</script>
</head>
<body>
<form onSubmit="return validate(this)">
<input type="text" name="textBox" id="textBox" />
<input type="submit" value="submit" />
</form>
</body>
</html>

Easier to just use:

if (frm.textBox.value == +frm.textBox.value) {// is a number
