angular - 不要从 Angular 表单发送值

Question

有什么方法可以不从表单向服务器发送值吗？

我有更新请求，在此函数中我不想发送 hospital.name(我试图将其设置为 null，但它无法正常工作。)

有什么办法可以忽略这个值吗？

      update(hospital: Hospital): Promise<Hospital> {
    const url =`${this.hospitalsUrl}/${hospital.id}`;
    return this.http.put(url, JSON.stringify(hospital), {headers: this.headers})
    .toPromise()
    .then(() => hospital);
  }

Answer 1

update(hospital: Hospital): Promise<Hospital> {
delete hospital.name;
    const url =`${this.hospitalsUrl}/${hospital.id}`;
    return this.http.put(url, JSON.stringify(hospital), {headers: this.headers})
    .toPromise()
    .then(() => hospital);

delete hospital.name; 将从对象中删除属性。

var myObject = {
    "name": "muthu",
    "id": "123",
    "password": "abc-123"
};
delete myObject.password;

console.log(myObject);
