Form Validation help!

[Brianfree]

Hi, how can i modify my code below to also check that the text field does not start or contain and spaces, underscores dashes etc... so it only has numbers or chars??

<script language="javascript" type="text/javascript">
function checkValue()
{
    if (document.form1.VRM.value == "")
    {    
        document.form1.SubmitButton.disabled=true;
        alert('Please enter a valid UK / Irish Numberplate.');
    } else {
        document.form1.SubmitButton.disabled=false;
    }
}
</script>

Kindet regards,

Brian
