Accessing instance values from javascript funtions

Hello All, I have a little question....

How can I access the instance's values from a javascript function...
I know I can access the values via xforms input element

Example:
Access the "name" element some like this ORBEON.xforms.Document.getValue(model('id'), '/name');

or

ORBEON.xforms.Document.setValue(model('id'), '/name', 'value');

<instance id="id">
    <customer>
          <name></name>
          <last-name></last-name>
    </customer>
<instance>

Hi Steve!!

I'm trying to access some instance's values from a  javascript. The fact is that I'm not using controls to ref some instance's elements, what I mean is that I have some instance's elments reference it (ref attribute) and other ones not (no input control for the element). The other ones (no input control for the element) are the elments that I'm trying to acces via javascript.

May be is just a little bit more clear!!!

Any Idea thanksssssssssssssss in advance!!!!!!!!!!!!!!!!

Victor,

 

As far as I'm aware the setValue and getValue seem to be the only JS methods to use OPS values in JS ... what exactly are you trying to achieve?? .... the one caveat with setValue/getValue is that you can not use setValue on an output ... only on an input.... but there are workarounds for this ... like an xforms:input that you make readonly with JS.

 

HTH.

Steve

Victor,

For security reasons, you can't access instances from JavaScript. If you
want to do that, you have to do it indirectly, the simplest way being to
use the JavaScript API to access an input control's value, but making
that control invisible with CSS. You probably have already seen the API
for accessing control values:

If we allowed JavaScript to freely access instances, anybody could hack
your application by writing a bit of JavaScript ;-)
