Titanium, display the value in XML from javascript?

Question

I need to get the textarea value from java script file. below is my code,

On click of button in index.xml, the control should go to getPrivacy_policy() and display the privacy page.

Privacy.xml

<Alloy>
    <Window id="privacyWin" title="Plan India" platform="android,ios">
        <View id="header">
              <Label id="title">Privacy Policy</Label>
        </View>

         <TextArea id="privacyID" suppressReturn="false"></TextArea>

    </Window>
</Alloy>

index.js

   function getPrivacy_policy()
    {
        var privacy_string = "some long text...";
        return privacy_string;
        var privacyPolicy = Alloy.createController('privacy').getView();
        privacyPolicy.open();
    }

How can display the privacy_string value in textarea which is located in privacy.xml?

Note that both (XML and Js) are different files.

Answer 1

In Alloy you can access the view elements by their ID, so you can do:

$.privacyID.value

which will return the text inside the TextArea
