    Validating 8 form fields with Javascript

    Hi all,

    I know this has probably been covered before ...

    I need to validate 8 seperate inputs in an HTML form using JS. I think I have got my regular expressions sorted I just need to bolt them to getElementById function. This is where I am having a brain freeze. Can anyone help me out, the first thing to validate is a 5 digit number between 0 and 99999 and not 00000

    thanks

    Perhaps a bit of code for others to look at can help...
    If your post falls off the page, bump it. ...
    Please remember to wrap any code you have in forum tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...

    I have got my number fields sorted I am struggling with date and time fields. I need to test a date in the format DD-MM-YYYY and a time in the format HH:MM:SS here is what I am trying

    /* validate Date Date */
    function validateDate() {
    var z = document.getElementById('Date').value;
    if (/^\d{4}[\/\-](0?[1-9]|1[012])[\/\-](0?[1-9]|[12][0-9]|3[01])$/) return true;

    else {
    document.getElementById("datemessage").style.display="inline";
    document.getElementById('Date').value= "";
    setTimeout(document.getElementById('Date').focus, 50);
    return false;
    }
    }
