Appcelerator Titanium Alloy | How to access element of other class - titanium

Question

In Alloy Titanium, I can access XML elements with their id $.element_id but how can I get elements of other class? or xml?
EDIT
I have two files.
1. file1.js, file1xml.xml
2. file2.js, file2xml.xml
In File1.js i want to access the variable of file2xml.xml. how can i achieve this?

Answer 1

Anything with an id can be accessed:
file1.xml
<Alloy>
<View id="myView" />
</Alloy>
file2.js
var ctrl1 = Alloy.createController('file1');
ctrl1.myView.backgroundColor = 'red';

Answer 2

if you have required file2.xml in file1.xml like
<Require src="common/viewToolBar" id="viewToolBar"/>
then you can get the element with the id in file1.js like
$. viewToolBar.getView('viewSynch').visible = false;

Answer 3

You can use Require tag in alloy with an Id and you can access its elements as below.
**File1.xml**
<Alloy>
<View>
<Label id="labelId">Middle</Label>
</View></Alloy>
**File2.xml**
<Window>
<Require src="File1" id="File1View" type="View"/>
<View id="header"><Label id="headerText">Header</Label></View>
<View id="nav">
<Label class="navButton" onClick="openTab" controllerName="home">Home</Label>
<Label class="navButton" onClick="openTab" controllerName="news">News</Label>
<Label class="navButton" onClick="openTab" controllerName="info">Info</Label>
<Label class="navButton" onClick="openTab" controllerName="more">More</Label>
</View>
</Window>
**File2.js**
$.File1View.labelId.text = "hi";
