Dynamically refering to elements

[taboca]

How can we dynamically access a given element. Lets say that I have about 50 views in a canvas document.

I would like to access the View1, View2, View3, based on a counter..

Something like document.getElementById and pass a string which is like f(counter).

Thanks,
Marcio

Every view has a subviews array, so you can reference a particular subview as follows:


<view name="myview">
<view name="a" />
<view name="b" />
<view name="c" />
</view>

<script>
var foo = myview.subviews[1];
</script>


... foo would be a pointer to the view named "b".

If you truly want a global way of addressing a view, you can give it a name instead of an id.

Ooops! I meant to say give it an id instead of a name, not the other way around.

If you say:


<view id="foo" />


Then you can address that view from anywhere in your app, just by writing "foo". No need for getElementById.

my code is like this:

var str_id = "justanid"
var etext = new edittext(someview);
etext.setAttribute("id", str_id);


how can I find out if a control already exists with the id str_id...

thanx,


Arthur.

That is, addressing the wrapper itself, or an element outside the wrapper.
