Angular 没有以角度获取反应形式中的所有值

我使用的是被动表单，并使用它提交给服务器。问题是我得到了一些表单字段值，但有些字段是空的。在下面的代码中，我得到了除税务组下的值之外的所有值。

taxesList

是动态加载的对象数组。如果你对此有任何解决办法，请帮助我

ngOnInit() {

   this.newproductfrm = this.fb.group({
        prdbarcode: ['', [Validators.required]],
        prdhsncode: ['', [Validators.required]],   
        prdname: ['', Validators.compose([Validators.required, Validators.minLength(2)])],
        category: [''],  
        subcategory: [''], 
        supplier: [''],
        pricing: this.fb.group({
            costprice: ['', Validators.compose([Validators.required,Validators.pattern(/^\d+\.\d{2}$/)])],
            mrp: ['', Validators.compose([Validators.required,Validators.pattern(/^\d+\.\d{2}$/)])],
            promo:['', Validators.compose([Validators.required,Validators.pattern(/^\d+\.\d{2}$/)])]
        }),
        inventory: this.fb.group({
            qty: ['', Validators.compose([Validators.required,Validators.pattern(/^\d+\.\d{2}$/)])],
            reorder: ['', Validators.compose([Validators.required,Validators.pattern(/^\d+\.\d{2}$/)])],
            unit: ['', Validators.required] 
        }),
        taxes: this.fb.group({
                exempt_tax: [''],
                taxid1: [''],
                taxid2: [''],
                taxname1: [''],
                taxrate1: ['', Validators.required],
                taxname2: ['', Validators.required],
                taxrate2: ['', Validators.required]

        })

   });

}

以下是表格代码

哪些未显示？税务组下未显示的值：税务：this.fb.group（{免税税：[''、taxid1：[''、taxid2：[''、taxname1：[''、taxrate1:[''、Validators.required]、taxname2:[''、Validators.required]，taxrate2:[''，Validators.required]}），我假设您在没有隐藏属性的情况下尝试了这个方法？那么它也不起作用了吗？有一些隐藏的表单元素和文本输入元素。。没有一个值被发布。。我正在附上发布数据的屏幕截图。但是，如果删除隐藏属性，或者更确切地说，将其设置为“文本”，它们会被发布吗？
