Hello All,

http://www.ibm.com/developerworks/xml/library/x-xformsjavascript/index.html

I have tried it but it did not display values.

Thanks,

Srikanth A

Re: Trying to access a instance in javascript

Hi Srikanth,

If you are trying to solve the "insert into empty node" problem the

article mentions, then you may want to look at the XForms 1.1

insert patterns that also solve this problem with an "context"

attribute:

http://www.w3.org/TR/xforms11/#insert-delete-patterns

Otherwise, OF keeps the instance on the server, not in an

object available directly to JavaScript. You can pass an

instance to JavaScript by serializing it and then parsing

it into a DOM object. There are some examples in the

list archives as well as insert examples.

HTH,

Hank

This article has been written for the Mozilla implementation of XForms
which is a pure client implementation.

When you use OrbeonForms, the architecture is pretty different and the
XForms document not being sent to the browser, the browser DOM has no
direct access to XForms elements (such as its model).

This doesn't mean that you can't use JavaScript, but you'll have to use
OrbeonForms specific methods, see
http://wiki.orbeon.com/forms/doc/developer-guide/xforms-extensions#TOC-JavaScript-Integration

Hope this helps.

Eric
