This question needs more context. Form Script? Plugin? Web Request? Language?

If it is a child record you can use the REST endpoint to query the database. If it is the primary contact you can use the Xrm.Page.Data.Attributes collection that is loaded by the application into memory on page load. I built a bunch of Open Source tooling (freely available at github.com/.../simplexrm) to make JavaScript easy in CRM, so you could write code like this:

function getChildContactIds (accountId) {

simpleXrmRest.query({

entity: "Contact", //entity schema name

select: "contactid", //comma separated list of attributes to return from server

filter: "ParentCustomer eq guid'" + accountId + "'",

callback: function () {

var results = simpleXrmRest.getRetrieveMultipleResults(this);

//handle results format [{contactid: "GUID1"}, {contactid: "GUID2"}]

}

})

}

function getPrimaryContactId () {

var result = simpleXrm.getLookupID("primarycontactid");

//handle result formatted as string

}

There are other toolsets out there and you should start by spending time with the SDK, but once you dig through it you will find that the simpleXrm toolset saves a lot of time and reduces your code's complexity.

Hi Suresh,

As per my understanding in your Account entity you have a lookup Contact.And you want to get that contact Id.If it is your requirement then try following code.

function getContactId() {

var ContactId = Xrm.Page.getAttribute("Contactfield logical name").getValue()[0].id;

alert(ContactId);

}

Hope it helps you.

Thanks,

Shiva.

Shiva, be very careful! Your approach will fail under multiple conditions. You have to build in null checks for lookups because they are complex (object nested in an array). If the lookup is empty, you will get an error because CRM.Page.getAttribute("attributename").getValue()[0] does not exist.

That is one of many reasons why I built the simpleXrm library. I got tired of pasting:

var results = null;

if (Xrm.Page.getAttribute(a).getValue() && Xrm.Page.getAttribute(a).getValue()[0] && Xrm.Page.getAttribute(a).getValue()[0].id) {

results = Xrm.Page.getAttribute(a).getValue()[0].id;

}

...Which is the "safe" way to do it in direct interaction with the SDK.

I like the compact

simpleXrm.getLookupID("attributename");

myself, it is much cleaner and informs future developers of the intent of the code.
