Default Auto update of text box/label

Dear Sir/Madam,

I have an ongoing issue with my ASP application. I am developing a Intranet site to enable employees to enter their holiday dates. When they enter the holiday dates I want to have a label or text box which updates with the number of days holiday they are requiring to book. Is this possible to do? Could you point me in the right direction. I am new to ASP and don't really know where to start.

Thanks in advance.


Simon Dilley.

If you want to do it entirely in ASP, you'll need to post the dates to the server then calculate the number of days and re-display the page including the calculated value and the original inputs.

Alternatively you could use a bit of javascript (or maybe even vbscript if your in an IE only intranet scenario) on the client-side which reads the input values, calculates the days and displays the result on the page without having to go to the server and back. Here's a quick 'n' dirty example which shows how to get values from input boxes and write to the page in client-side vbs.

<script language="VBScript">
Sub CalcDays()
    Dim dtStart, dtEnd, nDiff, sMsg

    dtStart = document.frmDate.txtStart.value
    dtEnd = document.frmDate.txtEnd.value

    If IsDate(dtStart) and IsDate(dtEnd) Then
        nDiff = 1 + DateDiff("d", dtStart, dtEnd)
        sMsg = nDiff & " days"
        sMsg = "valid dates only"
    End If

    document.getElementById("dvMsg").innerHTML = sMsg
End Sub
<form name="frmDate" id="frmDate">
Start Date : <input type="text" name="txtStart" id="txtStart"><br>
End Date : <input type="text" name="txtEnd" id="txtEnd"><br>
<div id="dvMsg"> </div><br>
<input type="button" value="Get Days" onclick="CalcDays">
