d00nson -> Setting value of a textbox based on another (1/1/2002 11:16:07)

Hi guys..can this be done?
Say I have a DRW generated dropbox list with values from a database. The dropbox is called "City_list" for arguments sake.
In the same form I have a textbox "City" with the initial value set to nothing. This is so I can type in any value I want. But say I wanted to insert one of the values into "City" from "City_list" by choosing it from the dropbox?
TIA!! and Happy New Year!

Its a function tha would need to be performed in javascript.

Heres my favorite resource :

Thanks Spooky. Is it because VBScript doesn't support server side?

VB does client side, but not fully supported.
JS does clientside very nicely.

Using serverside VB, means you need to "submit" the value so it shows when the page is reloaded. Client side, you dont.

Hi Spooky! Thanks for the link
I'm having some trouble implementing with Javascript. Shen I select from the dropbox, the textbox referenced in the javascript doesn't work. Code follows.

<form METHOD="POST" action="--WEBBOT-SELF--" name="addnewprod">

...FP save to database wizard stuff...

<table BORDER="0">

...other plain textbox fields...

<SCRIPT LANGUAGE="JavaScript"><!--
function updatebanking() {
document.addnewprod.banking.value =
document.addnewprod.banking_opt.options[document.addnewprod.banking_opt.selectedIndex].value
}
//--></SCRIPT>

<tr>
<td><b>banking:</b></td>
<td><input NAME="banking" SIZE="40"></td>
<td><select size="1" name="banking_opt" onChange="updatebanking()">
<option>1 of 1</option>
<option>2 of 1</option>
<option>3 of 1</option>
<option>4 of 1</option>
<option>2 of 2</option>
<option>4 of 2</option>
</select>Choose here or type your own.</td>
</tr>

...more textbox fields...

<td COLSPAN="3"><input TYPE="Submit" NAME="fp_submit"><input TYPE="Reset" NAME="fp_reset"></td>
</tr>
</table>
</form>

This should do it for you:

<SCRIPT LANGUAGE="JavaScript">
<!--
function updatebanking() {
var i = document.addnewprod.banking_opt.selectedIndex;
var strBanking = document.addnewprod.banking_opt.options.text;
document.addnewprod.banking.value = strBanking;
}
//-->
</SCRIPT>

Thanks Ginnie!

Works a treat. But what if the dropbox didn't have static values but was pulled from a database using DRW? Can you have a DRW embedded in another one?

Maybe I'm misunderstanding the need, but look at: http://www.sitebuilder.ws/frontpage/tutorials/update.htm.
Especially look down the page to the <%Request... part. Build a drop-down from the database with DRW, insert the request string into the form field properties as the initial value, and then make the drop-down post where you wish for it to post.
Good luck.

That shouldn't make any difference. The function is performed after the form is populated by the DRW and when the dropdown menu is changed.

Not sure about that one ... haven't really used the DRW. Anyone else know?

I am tearing my hair out trying to achieve this. I can't get javascript to work when you use database results as the drop down and then try to copy them automatically into a text box field any held would be appreciated.
