Can someone help me with this? there are 3 date fields:
day-month-year
. I want to pass the written three values into the hidden field. Example: 20-12-2006

Can you help me out? Do I have to set a function or can I do it with response.write or something ?


<input type="text" name="txtDD" id="datumDD" size="1" maxlength="2" onKeyPress="return isNumberKey(event)">-

<input type="text" name="txtMM" id="datumMM" size="1" maxlength="2" onKeyPress="return isNumberKey(event)">-

<input type="text" name="txtJJJJ" id="datumJJJJ" size="2" maxlength="4" onKeyPress="return isNumberKey(event)">

<input type="text" name="opleverdatum" id="opleverdatum" value="" />

First are you using asp or asp.net (looking at your code I would say you are using classic asp) and second are you looking for a server side solution or a javascript solution?

-------------------------
I will only tell you how to do it, not do it for you.
Unless, of course, you want to hire me to do work for you.

I'm using ASP. I'm working with a database and want also take the hidden field value to the next page. But for now I want a javascript solution.

I have tried this code:
<script>
document.getElementById('opleverdatum').value = document.getElementById('datumDD').value + document.getElementById('datumMM').value + document.getElementById('datumJJJJ').value
</script>

I find this code logical! But I get the next error:

document.getElementById('datumDD') has no properties

I have got the following code and it does work ^_^
Is there something to do better?

<script>
function passValue(){
document.getElementById('opleverdatum').value = document.getElementById('datumDD').value + '-' + document.getElementById('datumMM').value + '-' + document.getElementById('datumJJJJ').value
}
</script>
<form name="form">
<input type="text" value="" name="txtDD" id="datumDD" size="1" maxlength="2" onchange="passValue()" onKeyPress="return isNumberKey(event)">-
<input type="text" value="" name="txtMM" id="datumMM" size="1" maxlength="2" onchange="passValue()" onKeyPress="return isNumberKey(event)">-
<input type="text" value="" name="txtJJJJ" id="datumJJJJ" size="2" maxlength="4" onchange="passValue()" onKeyPress="return isNumberKey(event)">

<br /><input type="text" name="opleverdatum" id="opleverdatum" value="" />
<input type="button" value="klik" />
</form>

Well

If you just need to concat and add the date to a final textbox, then its fine with respect to javascript.
