CRM2011 Javascript判断用户是否拥有某种Role

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.results.length == 1)
        {
            var role = requestResults.results[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;
}

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

    return isEqual;
}

应用：

var isManager=UserHasRole("Manager");
if(isManager)
{
    //Do something
}
else
{
    //Do something
}
