Hide button on screen based on group/role

Need some assistance. I have a button on the HR11 screen that will launch a webpage. This works fine. But, we are rolling out in a phased approach to 40+ offices, 1-2 at a time and the powers that be do not want anyone seeing the button until it is their turn to go live. We are talking about 2-4 people per branch. Using the hammer approach I was able to get the code working below but it requires me to add user IDs every time a new office goes live. This requires a lot of extra red tape going thru QA and production control not to mention the extra coding on 5 screens that we have the button on. I am looking for a way to put the users in a role or group and be able to authenticate them in that role or group, but can’t seem to find a way. If I use portalWnd.oUserProfile.getAttribute("???") for group or role then it brings back only one out of the several that they are in. So it is not a guarantee that I get the group that I would use for the button group/role. Questions: 1) is there any way to loop through all of their groups/roles to match a particular one. 2) Is there a better mousetrap than the one I am using below? Thanks, Rudy Code: function FORM_OnAfterDataInit() {var str1="UserID1,UserID2,UserID3,UserID3 "; var UserId=portalWnd.oUserProfile.getAttribute("id"); //gets logged in user ID //alert(portalWnd.oUserProfile.getAttribute("group")); //UserId="u3lxd"; var iOk=str1.indexOf(UserId); //searches for a string w/in a string if (iOk==-1) { var objButton = lawForm.getFormElement("push11"); objButton.value=""; //hides button on screen } }
