View Full Version : [SOLVED] Make all existing Textareas in a form growable

31 May 2007, 7:40 AM
I have x number of existing textareas on a page. I want to make all of them growable without knowing the exact id.

The problem is that the methodology I'm using doesn't work right. It only sets the *last* textarea to be growable. When I look at the dom, each TextArea's className was updated with "x-form-textarea x-form-field", just like it's supposed to. It's just that the grow "event" doesn't work for any but the last textarea.

Here's an example of what I've tried:

<!doctype html public "-//w3c//dtd html 4.01//en" "http://www.w3.org/tr/html4/strict.dtd">
<link rel="stylesheet" type="text/css" href="../Ext/resources/css/ext-all.css">
<script type="text/javascript" src="../Ext/adapter/yui/yui-utilities.js"></script>
<script type="text/javascript" src="../Ext/adapter/yui/ext-yui-adapter.js"></script>
<script type="text/javascript" src="../Ext/ext-all.js"></script>
<script type="text/javascript">
//set all textareas to be "growable" ... i hope.
Ext.select("FORM TEXTAREA").each(function(element){
var grow = new Ext.form.TextArea({
width:400, grow:true
<form method="post" action="CreateFCCase.asp">
<textarea name="Description of Work Required" id="moddescriptionofworkrequired" cols="80" rows="3" class=""></textarea>
<textarea name="Any Additional Information" id="addanyadditionalinformation" cols="80" rows="3" class=""></textarea>

Now, I'm probably either approaching this the wrong way, or trying to do something that wasn't intended with Ext. But I figure it should be possible to quickly apply a base set of functionality to a "set" of form fields at once.

Any thoughts?

I did a pretty good scouring of the forums for any previous mention of this type of thing, but couldn't find anything. If there's a thread that covers this already, my apologies.

This might be b/c you're creating flyweight objects rather than real objects in the select. Try passing true as the 2nd arg.

That got it! Looks like I've got some reading to do on flyweight objects vs "real".

Thanks for the quick response!
