我在使用Typescript制作地图时遇到了一些问题。我的目标是使用类似于Java中的HashMap的数据结构。以下是我的Java对象示例：
public class Payment {
private String id;
private DateTime created;
//when they actually received the payment
private DateTime paidDate;
private String customerId;
private String companyId;
private BigDecimal amount;
private BigDecimal allocated;
private String description;
// it must be the Id of PaymentMethod
private String type;
//to improve it
private String currency;
private Boolean fullPaid = false;
private Boolean lockArchive = false;
//<InvoiceId, Amount>
private HashMap<String, BigDecimal> invoices = new HashMap<>();
//getter and setters....
所以我在Typescript中所做的是创建一个类似的类，例如：
export class Payment {
public id?:string;
public created?:string;
public paid_date?:Date;
public customer_id?:string;
public company_id?:string;
public amount?:number;
public allocated?:number;
public description?:string;
public type?:string;
public currency?:string;
public full_paid?:boolean;
public lock_archive?:boolean;
public invoices: {[invoice_id:string]:number};
constructor(id: string, created: string, paid_date: Date, customer_id: string, company_id: string, amount: number, allocated: number, description: string, type: string, currency: string, full_paid: boolean, lock_archive: boolean, invoices: { [p: string]: number }) {
this.id = id;
this.created = created;
this.paid_date = paid_date;
this.customer_id = customer_id;
this.company_id = company_id;
this.amount = amount;
this.allocated = allocated;
this.description = description;
this.type = type;
this.currency = currency;
this.full_paid = full_paid;
this.lock_archive = lock_archive;
this.invoices = invoices;
}
}
我正在尝试向发票映射中添加内容，因此我有以下函数：
public invoicesMap = new Map<string, number>();
constructor(public dialogRef: MdDialogRef<PaymentInvoiceSelectDialogComponent>,
private customerService:CustomerService,
private paymentServices: PaymentsService) {
}
ngOnInit() {
this.customer.subscribe((res)=>{
this.customer_name = res.customer_name
}, error=>{
console.error(<any>error);
});
this.customerService.getListOfCustomerInvoices(this.customerId,'0','25')
.subscribe( (res) =>{
this.invoices = res;
},
error => {
console.error(<any>error);
});
}
selectedInvoice(invoiceId: string, amount: number, event:any) {
if(event.checked){
if(!_.isEmpty(this.payment.invoices)){
for(let [key, value] of this.invoicesMap) {
if (key !== invoiceId) {
this.invoicesMap.set(invoiceId, amount);
for(let [key, vvalue] of this.invoicesMap) {
if (key === invoiceId) {
this.availableAllocation = this.availableAllocation - vvalue;
}
}
}
}
} else {
this.invoicesMap.set(invoiceId,amount);
for(let [key, vvalue] of this.invoicesMap) {
if(key === invoiceId){
this.availableAllocation = this.amount - vvalue;
}
}
}
} else if(!event.checked){
for(let [key, vvalue] of this.invoicesMap) {
if (key === invoiceId) {
console.log("removing an item");
this.availableAllocation += vvalue;
}
}
}
//at this point I would like to set this.payment.invoices to this.invoiceMap
for(let [key, value] of this.invoicesMap){
let v = {invoice_id:key,amount:value};
console.log(v);
}
this.payment.allocated = this.availableAllocation;
}
savePayment(){
console.log(JSON.stringify(this.payment));
// this.paymentServices.updatePayment(this.payment)
// .subscribe((res)=>{
// this.payment = res;
// this.dialogRef.close(this.payment);
// },
// error =>{
// console.log(<any>error);
// });
}
项目已添加到invoiceMap，但我现在遇到的问题是将invoiceMap添加到payment.invoices中。如果有人能指点一下方向，将不胜感激。谢谢。
