I think this is really to silly but I'vd been struggling with it for quite some time now so I hope one of you guys can give me the answer

I have a form with a field called gebruikersnaam, after changing te value I want to call a function that checks the value that was entered againt a database.

All goed well except for the fact that I am not able to retrieve en send the entered value to my function

HELP!!!

In the source below a call upon the function and I want to pass the entered value to the function (where it now says ??????)

<td colspan="3" class="leftreaddata"><input name="gebruikersnaam" onchange=<%=ControleerDubbel(??????,"Logingegevens","gebruikersnaam")%> type="text" id="gebruikersnaam" size="25" maxlength="25" />

Hi Pfishy,

maybe I misunderstand your problem, but AFAIK you can't ask your webserver
to insert the value of a text input at delivery time.

But this code

shows, how you can use "Me" to pass the current HTML element to a (client side) VBScript Sub.

correct,

you cannot check data with server-end languages immediatly. Therefore there are nice script languages like VBScript, JavaScript and ofcourse AJAX who greatly contribute in Client-side usage.

But in order to check the name with the Database entry, you will have to communicate back to the server with the information (which AJAX does 'on the fly') and then you will need to create a function in ASP where you will read the SERVER_REQUEST that will be shown in the URL. i.e. http://www.yournamehere.com/login.asp?naam=Jan&achternaam=Klaassen and your function will grab the 'naam' and 'achternaam' and parse it.

i.e. strNaam = Request.Form("frmNaam")

Thanks for the replies, for me it's stays confusion what is possible iin which language and what's not.

The reason I thought is should be possible is that the code below does retrieve the entered value on the fly and reacts on it without submitting the form, I'm just not sure which language this is...:-(

<input name="newcat" type="text" id="newcat" size="25" maxlength="25" onChange="categorie.options[categorie.length] = new Option(this.value, this.value);this.form.categorie.value=this.value;"/>

I did change my approach and created a function that is called upon when submitting and it works fine now!

To create a new function for it is much better, it is better to overview your code.....

And the language in your example looks like JavaScript...
