I have a web resource which is html/javascript and contains a button along with it's action code.

I have 2 questions

1. The code in the web resource can't access any xrm objects on the main form. For example I want to get a field value using the xrm getvalue().
I've tried both these but they both come back with the error '{fieldname} is undefined'

a. Xrm.Page.getAttribute({fieldname}).getValue();
b. parent.Xrm.Page.getAttribute({fieldname}).getValue();

2. In the web resource is it possible for the onclick action to call a javascript action which is in a javascript resource on the main form?

Thanks

I think maybe the CRM SDK may help you. I don't think it passes the context out to an HTML page by default

Try window.parent.Xrm...

Also review this post on referencing the ClientGlobalContext in a web resource:

Thanks for your replies.

Regarding Question 1 I had made a typo and left out the double quotes around the field name, the code below works.

parent.Xrm.Page.getAttribute("{fieldname}").getValue();

I'm still not sure about Question 2

I assume you are referencing to some function defined in JS web resource and registered on main entity form. If so, you can access function through HTML web resource as

window.parent.functioname();
