angular4响应式表单添加验证

Question

this.invoiceForm = this.formBulider.group(new Invoice());

如果以这种方式创建表单，要怎么加入验证器Validators？

Answer 1

一种方式：

this.invoiceForm = this.formBuilder.group({
    control1: new FormControl('',[Validators.required,...]),
    control2: new FormControl('',[Validators.required,...])
})

Invoice对象里面应该包含多个 FormControl 属性。
