Hi all

this is my approach to events and javascript on D365s fields.

I want set the default value of this lookup field.

this is my library/javascript (cr07a_ATHsetLookupFieldUtentiCollegatiOpportunity)

//-------------------------------------------------------------------------------------------
// setTextField
//-------------------------------------------------------------------------------------------

function setTextField(e){

// Get the Form Context
var formContext = e.getFormContext();

// Set the 'User Scope'[dev1_idcollegamentocr07a_athambuteopportunity] to a variable
var ValDefault = "Customer Relationship Management"; <-- (here I try also with IDvalue [078d7702-2581-ec11-8d21-0022489ea185])
formContext.getAttribute("dev1_idcollegamentocr07a_athambuteopportunity").setValue(ValDefault);

}

but the default "Customer Relationship Management" is not show on field.

Where I'm mistaken?

thanks for any reply and suggestion

Hi,
You are welcome.
You didn't find all events list because you select the wrong item which should be added the event.

This may help you find the right form. Then the On Load event will show on the right.

I dont find the event OnLoad on "Event Type", in the list appears only the event "In case of modify" .... where I'm mistaken?

Hi a33ik

I miss your question (Also I have a question - when do you want to assign that default value? It's logical to do that on the form onload.)

Yes I want assign default value on load form

Answering your questions.

"Pass Execution Context":

In regards to your code - id should be the Guid (like "dc45213e-bf48-ed11-bba1-0022482dbb3a") of the record and entityType should be the Logical Name (like "account").

RE: set default value on a field

Hi,

You need to check the following four points.

In order for javascript to work, we should add the event to the field which is regarded as a trigger.

For example ,you want to set the default value to field A when the field B change, then you can add the event to the field B.

2. Check the "Pass Execution Context as a First Parameter" checkbox in the even handler.

3. The Function Name should be “setTextField” not “addPreSearch” according to your code.

4. Because you’re setting the default value for a look up field, we can’t set a string for it but an array instead.

I tried to modify your code for your reference.

function setTextField(e){ // Get the Form Context var formContext = e.getFormContext(); var ValDefault=new Array(); ValDefault[0] = new Object(); ValDefault[0].id ="The Guid of the record"; //(Guid is the unique id of the record, you can find it by click on the table corresponding to the lookup field, or find it in the URL of the record which you selected as the default value) ValDefault[0].entityType ="The logical name of the entity which associates with the lookup field "; ValDefault[0].name = " Customer Relationship Management"; // Set the 'User Scope'[dev1_idcollegamentocr07a_athambuteopportunity] to a variable formContext.getAttribute("dev1_idcollegamentocr07a_athambuteopportunity").setValue(ValDefault); }
