Hi again.
Having a little trouble working this one out, was hoping someone had experienced and cracked the problem:

I'm trying to auto populate a form field with the data from another field (a drop down list).
Ordinarily, not a problem:

code:

<script language="JavaScript">

function printVals(x) {

	with (document.forms["myForm"]) {



	var getIt1 = item1.value

	var getIt2 = item2.value

	var getIt3 = item3.value



	if (x == 1) {

		Show1.value = getIt1

		Show2.value = getIt2

		Show3.value = getIt3

		}

	}

}



etc...

However... the list I'm accessing is linked to a database, and I'm using Visible names, with actual values being an ID:

code:

<option value="ItemID">itemName</option>

For whatever reason, I can't figure out how to select the VISIBLE name, and show that on the page (for printing out).
The ID is then passed to the database and stored (got that bit cracked... just can't get my head around the other).

Please help!
Thanks again

More HTML/Javascript, but here's how you can loop a dropdown and pick what you need:

code:

<HTML>

<HEAD>

<TITLE>LoopDaDropBox</TITLE>



<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">

<!-- ;

function popEm(){

	thing = document.forms[0].dropBox;

	for(i=0;i<thing.length;i++){

		alert(thing[i].value);

		alert(thing[i].text);

	}

	alert("selected value is: " + thing.options.selectedIndex);

}

// -->

</SCRIPT>

</HEAD>



<BODY>



<FORM ACTION="#" >

<SELECT NAME="dropBox" onchange="popEm()">

<OPTION value="0"> - Select value - </OPTION>

<OPTION value="1">Value 1</OPTION>

<OPTION value="2">Value 2</OPTION>

<OPTION value="3">Value 3</OPTION>

</SELECT>

</FORM>



</BODY>

</HTML>

{cell 260}

Nice code DmS, but unfortunately, it doesn't address my problem (or I can't see the answer at least).

Assume I select "Value 1"
Your output says: "selected value is: 1"
I need to capture the label, so it would say: "selected value is: Value 1"

I can already get the value, just can't work out how to capture the label.

I've even looked into applying the label property: <label for="ItemID">Item Name:</label>
But my drop-down is created on the fly (VBScript ASP) and this seems to be where I'm struggling.

| |EDIT| |
I don't believe it!
Took some working out, but I seem to have cracked this one:

code:

<script language="JavaScript">

function printVals(x) {

	with (document.forms["myForm"]) {

	

	var itemIndex = itemID.selectedIndex

	var itemText = itemID.options[itemIndex].text

	



	if (x == 1) {

		itemShow.value = itemText



		}

	}

}

</script>



<input type="Button" onClick="printVals(1)">

It was a pain, but I had no idea that JavaScript accessed the element in such a roundabout way...
First get the index, then get the text that relates to that index, then print that text... sheesh!

Just took a little patience, (and google).

Indeed, it often seems to be the way:

Have a problem, can't find an answer.
Post problem on Asylum.
While thinking how to best word request, realise possible solution.
Go and play with idea.
Meanwhile - someone responds... a light blinks on...
Find answer and post it.
(Funny how so many people find their own solution after posting here)

Job done.

Thanks again
