drop down box - 8/17/2008 21:30:14
I have a dropdown box and would like to have a textbox equal a value based on the value in the dropdown. I'm using the following code but it does nothing. Can someone tell me what I'm doing wrong? Thanks.
The form name is TS.
<script>function updateTextBox(val)
{
if(val == "aaa")
{
document.forms['TS'].elements['State'].value = "Test";
}
else if(val == "ccc")
{
document.forms['TS'].elements['State'].value = "Test2";
}
}
</script>
<select onchange='updateTextBox(this.value)' name="TSCodeBox" size="1">
<option selected>Select</option>
<option>aaa</option>
<option>ccc</option>

This way work any better?
document.getElementById("State").value = 'Test';

Oh wait. Ooops, there was a lot more that I should have seen. The selection of the dropdown box as the biggie. What you need is a little JS to figure out which option is selected.
I'd try it something like so:
...
if(document.TS.TSCodeBox.options[document.TS.TSCodeBox.selectedIndex].value == 'aaa')
{
document.getElementById("State").value = 'Test';
} else {
...
but you must give your text box an id="State" as well a name="State" tag. Well, you really don't need the "name" tag but to use getElementById you need an "id" tag to get.
Make sense? That help any?

Still nothing? When I select the aaa nothing changes in the text box.

I created a page from that code and can't get it to work?
Do you have a URL for that page you're creating? It could be something else entirely and I'd just like to double check.
I say that because I use that code in a lot of places; maybe not in that exact specific way but that's fairly standard JS stuff being used everywhere and it'll be easier for me if I have a specific page to look at.

Here is my version of that page:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>New Page 1</title>
<meta name="GENERATOR" content="Microsoft FrontPage 4.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<script>function updateTextBox(val)
{
if(val == "something")
{
document.getElementById("myTextBox").value = "something based on something";
}
else if(val == "something else")
{
document.getElementById("myTextBox").value = "something based on something else";
} else if(val == "aaa")
{
document.getElementById("myTextBox").value = "something based on aaa";
}
}
</script>
</head>
<body>
<form method="POST" action="--WEBBOT-SELF--" name="myform" id="myform">
<!--webbot bot="SaveResults" startspan U-File="../_private/form_results.csv"
S-Format="TEXT/CSV" S-Label-Fields="TRUE" --><input TYPE="hidden" NAME="VTI-GROUP" VALUE="0"><!--webbot
bot="SaveResults" endspan -->
<p>
<select size="1" name="D1" onchange='updateTextBox(this.value)'>
<option selected>aaa</option>
<option value="something">something</option>
<option value="something else">Something else</option>
</select></p>
<p> </p>
<p><input type="text" name="myTextBox" id="myTextBox" size="50"></p>
<p> </p>
<p> </p>
<p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p>
</form>
</body>
</html>
That domain looks quit familiar to me.

Thanks again!!!
