You can use: /^[1-9]+[0-9]*$/

<script type="text/javascript">
<!--
function validate(field) {
    if( !field.value.match(/^[1-9]+[0-9]*$/) )
    {
        alert("Invalid entry! Only numbers more than zero are allowed");
        field.value = '';
        field.focus();
        return false;
    }
    else
    {
        return true;
    }
}
//-->
</script>

<input type="text" name="numeric" onblur="validate(this);" />


Kind Regards
Bakr
