Hiding Navigation in CRM 2011

To hide the navigation option in CRM 2011, we can use the below function.

Ex: I am hiding 'RelationShips' Options from Opportunity Navigation.

HideRelationshipsNav("Relationships");

function HideRelationshipsNav() {
        var navBar = document.getElementById("crmNavBar");
        if (!navBar) return;
        var optionItems = navBar.getElementsByTagName("nobr");
        var exitCount = 0;
        for (opt = 0; opt < optionItems.length; opt++)
            for (a = 0; a < arguments.length; a++)
            if (optionItems[opt].innerText == arguments[a]) {
            optionItems[opt].parentNode.style.display = "none";
            exitCount++;
            if (exitCount == arguments.length) return;
        }
    }

'Access denied' While Accessing CRM Current User Role

I faced some problem while accessing the CRM Current user role with the below code snippet. Then i did some research and found the solution for the same.

 function UserHasRole(roleName) {
             var serverUrl = Xrm.Page.context.getServerUrl();
             var oDataEndpointUrl = serverUrl + "/XRMServices/2011/OrganizationData.svc/";
            oDataEndpointUrl += "RoleSet?$top=1&$filter=Name eq '" + roleName + "'";
            var service = GetRequestObject();
            if (service != null) {
                service.open("GET", oDataEndpointUrl, false);
                service.setRequestHeader("X-Requested-Width", "XMLHttpRequest");
                service.setRequestHeader("Accept", "application/json, text/javascript, */*");
                service.send(null);
                var requestResults = eval('(' + service.responseText + ')').d;
                if (requestResults != null && requestResults.length == 1) {
                    var role = requestResults[0];
                    var id = role.RoleId;
                    var currentUserRoles = Xrm.Page.context.getUserRoles();
                    for (var i = 0; i < currentUserRoles.length; i++) {
                        var userRole = currentUserRoles[i];
                        if (GuidsAreEqual(userRole, id)) {
                            return true;
                        }
                    }
                }
            }
            return false;
        }

When the user tries to execute the code, he/she will get 'Access denied' Error in CRM page.

Solution :

To resolve this error, we need to replace the 'var serverUrl = Xrm.Page.context.getServerUrl();' code with the 'var serverUrl = "/" + Xrm.Page.context.getOrgUniqueName();'.

            }
            return false;
        }
        function GetRequestObject() {
            if (window.XMLHttpRequest) {
                return new window.XMLHttpRequest;
            }
            else {
                try {
                    return new ActiveXObject("MSXML2.XMLHTTP.3.0");
                }
                catch (ex) {
                    return null;
                }
            }

        function GuidsAreEqual(guid1, guid2) {
            var isEqual = false;
            if (guid1 == null || guid2 == null) {

            }
            else {
                isEqual = guid1.replace(/[{}]/g, "").toLowerCase() == guid2.replace(/[{}]/g, "").toLowerCase();
            }
            return isEqual;
        }
