Javascript 当我更新时，信息消失了

我正在编写一个代码，用户可以在其中更新一些数据。当用户第一次保存信息时，屏幕上的信息消失。然后，当我第二次单击编辑按钮时，编辑对话框没有打开，我得到下面的错误。有什么问题吗？

下面是编辑对话框组件的HTML和TS的一个小片段：

<div fxLayout="row" fxLayoutAlign="start center">
                <mat-form-field appearance="outline" fxFlex="100" fxFlex.gt-xs="40" class="w-100-p pr-8">
                    <mat-label>Receipt Code</mat-label>
                    <input matInput formControlName="StockIntegrationCode" type="number">
                </mat-form-field>
                <mat-form-field appearance="outline" fxFlex="100" fxFlex.gt-xs="40" class="w-100-p pr-8">
                    <mat-label>Receipt Name</mat-label>
                    <input matInput formControlName="Name" type="text">
                </mat-form-field>
            </div>
        <button mat-stroked-button class="amber-fg pr-4" (click)="save($event)"> Kaydet</button>

你能把你的代码贴在你声明的

setReceiptItems

method/setter的地方吗？错误表明您正在尝试将属性添加到布尔值。我编辑了postNow，显示了您声明

receipt

组件成员（this.receipt）的部分。在

this.receipt.packagingereipts=receipts行之前，也将其记录到控制台您可能会在那里得到一个布尔值，而不是您所期望的值。除此之外，您还可以将循环替换为
let receipts:irecept[]=this.dataSource2.data.map（d=>{return d.receiptas irecept}）
也许您的问题在于
这一点。\u dialogRef.close（true）尝试
此操作。_dialogRef.close（响应）只是在黑暗中射击谢谢你，你是对的问题是
这个
save(e) {
        e.preventDefault();
        if (this.form.valid) {
            this.receipt.Name = this.form.controls["Name"].value;
            this.receipt.ReceiptType.Id = this.form.controls[
                "ReceiptType"
            ].value;
            this.receipt.ReceiptGroupType.Id = this.form.controls["ReceiptGroupType"].value;
            this.receipt.StockIntegrationCode = this.form.controls[
                "StockIntegrationCode"
            ].value;

this.confirmDialogRef.componentInstance.confirmMessage =
                "Receipt will be changed, are you sure?";

            this.confirmDialogRef.afterClosed().subscribe((result) => {
                if (result) {
                    this._productionService
                        .saveAndGetReceipt(this.receipt)
                        .subscribe((response: IReceipt) => {
