Datepicker Input in Lightning Web Component - salesforce

Question

I want to any pass date value from Datepicker input of lightning web component to PostingDate variable in LWCcontroller.cls
import { LightningElement,api ,track} from 'lwc';
import getInvoiceData from '#salesforce/apex/CustomerRefundLwcController.getInvoiceData';
import getBankAccounts from '#salesforce/apex/CustomerRefundLwcController.getBankAccounts';
import processCustomerRefund from '#salesforce/apex/CustomerRefundLwcController.processCustomerRefund';
export default class CustomerRefund extends LightningElement {
#api recordId; /*Sales Credit Id*/
#track invoiceData;
#track invoiceLinesData;
#api headerText;
#api recordProcessing;
#api bankAccounts = new Array();
#track selectedBankId;
#track allocateToSalesCredit;
#track referenceDetail;
#track bShowModal = false;
#track PostingDate;
/*Toast Event Variables*/
#api isError = false;
#api iswarning = false;
#api issuccess = false;
#api ToastMessage;
PostingDateChange(event)
{
this.PostingDate = event.target.value;
this.invoiceData.PostingDate = this.PostingDate;
}
processRefundHandler() {
this.recordProcessing = true;
//console.log('this.formData----'+JSON.stringify(this.invoiceLinesData));
console.log('this.formData----'+JSON.stringify(this.invoiceData));
processCustomerRefund({ lstInvoiceLines : this.invoiceLinesData, bankId : this.selectedBankId, allocateToSalesCredit : this.allocateToSalesCredit, reference : this.referenceDetail, postingdate : this.PostingDate })
.then(result => {
var responseMessage = result;
this.recordProcessing = false;
this.ToastMessage = responseMessage;
if(responseMessage == "Success"){
//this.issuccess = true;
this.isError = false;
this.ToastMessage = "Your Bank Customer Refund has been created";

Answer 1

You need to add the new parameter postingdate to the Apex Method
#AuraEnabled
public static string processCustomerRefund (
List lstInvoiceLines,
String bankId,
Boolean allocateToSalesCredit,
String reference,
Long postingdate
) {
I'm not sure long is the correct type thought, maybe DateTime or Date, I don't remember how Salesforce handle this. If it's long, it would be a timestamp.

Answer 2

Lightning input (type="date") returns a string in YYYY-MM-DD format.
Here's what I did:
public static Date convertDate(String datestr){
List<String> dateSplit = datestr.split('-');
return Date.newInstance(Integer.valueOf(dateSplit[0]), Integer.valueOf(dateSplit[1]), Integer.valueOf(dateSplit[2]));
}
You could also simply use Date as a parameter type in the apex method and that should work as well.
