Another Solution would be to save the TextArea instance with setUserData inside
the button:
var txt = new qx.ui.form.TextArea();
var btn = new qx.ui.form.Button("btn", "icon/22/apps/internet-web-browser.png");
btn.setUserData("myTextArea", txt);
btn.addListener("execute", function(e) {
alert(e.getTarget().getUserData("myTextArea").getValue());
//this.__saveDataToDB();
}, this);
I just hacked this code inside the email, it's not tested but should work ;)

Andreas

Thanks very much!
It's OK to bind listener to correct text area.
BUT, Another question :
-------------------
...
var txt = new qx.ui.form.TextArea();
var btn = new qx.ui.form.Button("btn",
"icon/22/apps/internet-web-browser.png");
btn.addListener("execute", function(e) {
alert(this.getValue());
// In Here,
// If bind listener to 'txt', not 'this', How to call the APP instance
method, such as '__saveDataToDB()' ?
}, txt);
...

Hi,
your variable txt holds only the last reference your loop creates.
One way to do what you want is binding the listener context to the correct text
area:

In my sample, do follow step:
1) select 'A' tab
2) enter 'hello' string in TextArea
3) click 'btn' button
My question is :
why the alert dialog show the 'null' string?
If I want to show 'hello' string in alert dialog, how should I do?
Thanks,
Wang Feiku
