  第二种: OData方式

//功能说明: 获取当前用户是否具有该角色
//备注:               
//参数说明:
//          roleName: 角色名称
//返回值说明(return):
//          bool:

function CurrentUserHasRole(roleName) {

    //为了避免OData中文检索不出这种问题,使用encodeURIComponent来encode;
    var serverUrl = Xrm.Page.context.getServerUrl();
    var oDataEndpointUrl = serverUrl + "/XRMServices/2011/OrganizationData.svc/";
    oDataEndpointUrl += "RoleSet?$top=1&$filter=Name eq " + encodeURIComponent (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[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;
}

//功能说明: 获取请求体
//备注:               
//参数说明(Parameters):
//返回值说明(return):
//          RequestObject
function GetRequestObject() {
    if (window.XMLHttpRequest) {
        return new window.XMLHttpRequest;
    }
    else {
        try {
            return new ActiveXObject("MSXML2.XMLHTTP.3.0");
        }
        catch (ex) {
            return null;
        }
    }
}

//功能说明: 比较两个Guid
//备注:               
//参数说明(Parameters):
//         guid1:Guid
//         guid2: Guid
//返回值说明(return):
//          bool:
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;
}
