Lightning Web组件中的日期选择器输入

Question

我想将闪电web组件的Datepicker输入中的任何日期值传递到LWCcontroller.cls 中的PostingDate变量

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";
this.bShowModal = true;
}else{
this.isError = true;
}
})
.catch(error => {
this.isError = true;
this.ToastMessage = error ;
console.log(error);
});
}

<div class="slds-col"> 

<label class="slds-form-element__label slds-no-flex">Posting Date</label>
<lightning-input type="date" 
name="Postingdate" 
value={PostingDate}

Answer 1

您需要将新参数postingdate添加到Apex方法

@AuraEnabled 
public static string processCustomerRefund (
List lstInvoiceLines,
String bankId,
Boolean allocateToSalesCredit,
String reference,
Long postingdate
) { 

我不确定long是正确的类型，可能是DateTime或Date，我不记得Salesforce是如何处理的。如果它很长，它将是一个时间戳。

Answer 2

Lightning输入(type="date"返回YYYY-MM-DD格式的字符串
以下是我所做的：

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]));
}

您也可以简单地在apex方法中使用Date作为参数类型，这也应该有效。
