How to populate lookup field dynamically client side

My mission is to copy a record in client side (no plugins) so using onload event I'm calling a function that fetching an object with all my attributes(to be copy to..), I can fill simply all fields in my form except from lookup field. I have in my data from my fetch 3 values to use: name: the data shown in the field' value: the guid of the entity reference and a number of type.. To populate a lookup field I need the name of the entity the id and type.

Two questions rise up:

1.Is the type value usable to populate the entity type field if yes then how? 2.Can I populate the name attribute in the new field as is from the old field?

Example of the data that I get :

Attributes
:
name
:
"this is the name"
type
:
"10026"
__proto__
:
Object
Value
:
"{6BddfDC-8B10-47F4-BC49-A537d2E43E}"

Hi,

refer to below post on how to set lookup field using JS

www.magnetismsolutions.com/.../how-to-get-and-set-a-lookup-field-using-javascript-in-dynamics-365

recordid is would be = {6BddfDC-8B10-47F4-BC49-A537d2E43E}

recordName would be = "this is the name"

entityName would be = the entity name , you cannot use Object Type code (10026)

Sample Code

functin SetLookup()

{

var lookupValue = new Array();

lookupValue[0] = new Object();

lookupValue[0].id = "92EC3861-8D59-E811-815C-080027878DE4";

lookupValue[0].name = "Custom Team";

lookupValue[0].entityType = "team";

Xrm.Page.getAttribute("fieldname").setValue(lookupValue);

}

Hey Wei

I know the basic way to popualte, but my case is that I don't know the Entity name a head, the function is generic dynamically, can I know by the type that I get the entity name?

Hi,

use webapi to query the metadata. below is the sample, but you have to modify a little bit.

Hi ,

You need to pass entity name to populate the lookup which is mandatory . Seems you have objecttypecode so you can easily retrieve dynamically the entity name using web API.

Here is the web API query to retrieve the entity name.

xxxxxxxx.api.crm.dynamics.com/api/data/v8.2/EntityDefinitions?$select=LogicalName,ObjectTypeCode&$filter=ObjectTypeCode eq 10026

You can refer below reference to know more about retrieve metadata using WebAPI.

Hope this helps.

Hi,

Try with this , please change the version as per your CRM instance .

var req = new XMLHttpRequest(); req.open("GET", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/EntityDefinitions?$select=LogicalName,ObjectTypeCode&$filter=ObjectTypeCode eq 10026", true); req.setRequestHeader("OData-MaxVersion", "4.0"); req.setRequestHeader("OData-Version", "4.0"); req.setRequestHeader("Accept", "application/json"); req.setRequestHeader("Content-Type", "application/json; charset=utf-8"); req.setRequestHeader("Prefer", "odata.include-annotations=\"*\""); req.onreadystatechange = function () { if (this.readyState === 4) { req.onreadystatechange = null; if (this.status === 200) {
debugger; var result = JSON.parse(this.response); var logicalName = result["LogicalName"]; } else { Xrm.Utility.alertDialog(this.statusText); } } }; req.send();
