Problem: I create a record when a user enter a value in the Return To Sender field. What i'm trying to do, is only display the data if the record exists and has the same doNbr as the one already on the page (the DO # displayed on the page is not stored on SF). But right now, if I enter a value on the field, it displays on every package section no depending on the doNbr like I want. Please find a screenshot of the page: enter image description here

When creating the record, I retrieve the doNbr, and save it on a doNbr field on the object. It works fine as you can see from the screenshot below.

  • hi, sort of! If I put "Yes" on package A and then "No" on package B, it will work as intended, and I will the see the values in the right place. However, if I put "Yes" on package A but nothing on package B, "Yes" will be displayed in both packages. I'll update my post with the code though

you are just pushing data into your array without removing/checking for duplicates.

I would recommend you change your approach.

declare a property which contains an array of objects which corresponds to each of the order's.

in your template, you can iterate over your property to display each of the orders and from the "input" fields, modify the objects in the property directly. this will avoid you the headache of having to check for the "index" of the item in the array to either update or add.


orderProperty = [{Id: '123213213, Do_Nbr__c: '123123}] //(can include more)

you can then use a template directive for:each={array} to iterate and render your order data.

and when you change or update your <lightning-input> element, using handleReturnToSenderChange, instead of checking for the index value: let index = event.target.dataset.index; you can use Array.prototype.find() method to find the object corresponding to your order number and modify the value.
