JScript to Show/Hide Web resource on form

Hi, I have a requirement for a simple JScript function.  I think I can piece together some of it as a non-developer, but am looking for the code regardless

Requirement: on Load/Save of form, or when field "dealreviewtype" = 'Green Folder Review', show web resource "publisher_webresourcename".  Else, on Load/Save of form, or when field "dealreviewtype" = 'LOI Review' or ' Contract Review', hide web resource "publisher_webresourcename". 

Any help is appreciated!

Thanks again.
