CRM2011 How to get object type code by entity name in Javascript?

Question

I have a lookup field in the form, before select the related entity for the lookup, I check some conditions, if not pass, I overwrite the lookup onclick event to alert user; else, I need to overwrite the onclick event to show the lookup window to allow user to select entity.

So I need the object type code of this lookup, but before select there is no value then I can't get the object type code by use this code: var objecttypecode = Xrm.Page.getAttribute("field id").getValue()[0].type;

How to get object type code by entity name?

I find out the way: function GetObjectTypeCode(entityName) { try { var lookupService = new RemoteCommand("LookupService", "RetrieveTypeCode"); lookupService.SetParameter("entityName", entityName); var result = lookupService.Execute(); if (result.Success && typeof result.ReturnValue == "number") { return result.ReturnValue; } else { return null; } } catch (ex) { throw ex; } } — nixjojo

        lookupService.SetParameter("entityName", entityName);

        if (result.Success && typeof result.ReturnValue == "number") {
            return result.ReturnValue;
        }
        else {
            return null;
        }
    }
    catch (ex) {
        throw ex;

While this may work now, to my best knowledge, using RemoteCommand in custom code has always been unsupported and is not guaranteed to always work.

The GetObjectTypeCode(entityName) method mentioned above will not work in a HTML web resource because a HTML web resource is always contained within an IFrame & calling the CRM methods becomes a challenge.

@GCATNM: While you are absolutely right, I think the simplicity & lightweightnes of the RemoteCommand justifies this approach above the RetrieveEntityMetaData approach

@Arsenal: The justification of using unsupported and undocumented APIs is debatable. If simplicity outweighs putting oneself (and a potential customer) at the risk of having your code broken by future CRM updates, that may "justify" it for the individual. I highly doubt it can be called good practice if you're concerned with quality and reliability.

One of the supported way of doing this is using the Metadata service and then retrieving the Object Type Code or etc (entity Type Code).
