如何仅重置角度 5 中的特定表单字段

我在我的一个组件文件中创建了一个函数来重置表单(myform):

I have created a function in one of my component file that resets the form(myform):

`onSubmit() {
  if (this.myform.valid) {
    console.log("Form Submitted!");
    this.myform.reset();
  }
}`

它可以很好地重置整个表单，但是否可以只重置一些元素并保持其他元素不变.

It works perfectly fine resetting the whole form, but is it possible to just reset some of the elements and keeping other the same way.
