How to Use JavaScript to Adjust Controls Like Toggles

Posted on by Sean Henderson

Hi,

I have JavaScript on my form to disable a two-option field, based on the value of a lookup. Without putting the entire function here, basically I'm using:

formContext.getControl(approvalToggle).setDisabled(true);

This function runs both on load and on change of the lookup fields. My script sets the default to disabled if the lookup is empty. When a specific value is used in the lookup, then the two-option field becomes enabled.

This works just fine. The problem is that if I use the Toggle control on the field, the field can be enabled with the right lookup value, but the control itself remains disabled.

For example:

In the first row, the Toggle control isn't being used and the lookup has the right value to unlock the field. Everything is working fine. In the third row, the lookup is empty, the field is locked, also everything working fine. But in the second row, the lookup has the right value to unlock the field (you can see the lock icon disappears) but the Toggle control remains inoperable. If I save, then refresh the browser (chrome or edge, same issue) then the Toggle control becomes active.

So I guess controls on fields have to be referenced separately? Does anyone know how to do this?

Hi Partner,

About this requirement, I suggest you to use Business Rules instead.

For example I created a business rule to check if the account is "Fourth Coffee" then unlock the "Director Approval"(Locked in default as yours).

And let's have a try. When loading the form with no data in Account, the fields are locked as we expected.

Then we choose the right account, the Director Approval get unlocked.

And if we selected other wrong account, the Director Approval get locked again.

The business rule will always be available both in onloading the form or onchanging the field without refresh the form.

And in your case, there may be some mistake in your logic code, to find out the reason, please share your complete code here.

On the whole, using Business Rules to control the fields will be easier and more accurate than JS code now.

Best Regards,

Leo

Hi, thanks for your reply!

A couple things:

1) I simplified the scenario for the purpose of highlighting the issue. In my actual solution, the custom code is doing quite a bit more heavy lifting and business rules can't even come close to handling it.

2) The issue isn't with the ability to lock and unlock a field at the field property level, I can do that easily enough in javascript. The issue is with the Toggle control. It looks like in your example, you didn't add the control, you just have the default yes/no box. I even tested this out with a business rule and it has the same issue. It properly unlocks and locks the field property, but the Toggle control itself remains inoperable. Add the Toggle control to your field and you will see what I mean.

Hi Sean,

Thanks for your details, I tried as you said and it is a known issue.

Toggle control is not recommended to use in D365 now, please use the default control instead.

Sorry for the inconvenience :(

Best Regards,

Leo
