How to hide save button / read mode only in browser adobe viewer?

Question

Currently I embed a pdf to my website , the problem is, I would like to show the read mode only instead of a full tool bar to the visitor , also , I would like to hidden the save file option .
I checked there is an open parameter in the offical document that can specific
toolbar=1&navpanes=0&statusbar=0&messages=0
However, can I specific what opition is allow in the toolbar (actually I would like to allow only zoom function )
Are there any way to doing this? Thanks.

Much of the documentation for Acrobat JavaScript has not changed and still operates exactly as it did with Acrobat 3.1 so it is possible that the old documentation is still valid. I have found that the Acrobat JavaScript Guide fro
version 5 has some very excellent documentation about the field object UI for the various form Fields.
If one goes to the Acrobat Developer Center and uses the Working with Distiller, Fonts and more and the uses the PDF Open Parameters one gets the documentation from the version 9.0 SDK form June 2008. This document probably has not been updated since then.  Another issue to consider is the changes in IE, the number of new web browsers, and the introduction of HTML 5 all of which could change how parameters are passed or allowed. This technique has always been problematic.
Within an external viewer, it is not possible to show/hide the toolbars.
