javascript - 模块 'FormBuilder' 导入了意外值 'AppModule'。请添加@NgModule 注解

Question

如何在app.module中添加formbulder

由模块 AppModule 导入的意外值 FormBuilder。请添加@NgModule 注解。

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule, HTTP_INTERCEPTORS } from "@angular/common/http";
import {FormBuilder, FormControl, FormGroup, Validators, FormsModule} from '@angular/forms';

    import { AppRoutingModule } from './app-routing.module';
    import { AppComponent } from './app.component';
    import { ClientComponent } from './client/client.component';
    import { ClientTaskComponent } from './clienttask/clienttask.component';
    import { ClientService } from './client/sherad/client.service';


    @NgModule({
      declarations: [
        AppComponent, ClientComponent, ClientTaskComponent, ClientService
      ],
      imports: [
        BrowserModule,
        AppRoutingModule,
        HttpClientModule,
        FormsModule,
        FormBuilder,
        FormGroup,
        FormControl
      ],
      providers: [],
      bootstrap: [AppComponent]
    })
    export class AppModule { }

import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { HttpClientModule, HTTP_INTERCEPTORS } from "@angular/common/http"; import {FormBuilder, FormControl, FormGroup, Validators, FormsModule} from '@angular/forms'; ........................///Remove this

import { FormsModule, ReactiveFormsModule } from "@angular/forms";..........//Add this

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { ClientComponent } from './client/client.component';
import { ClientTaskComponent } from './clienttask/clienttask.component';
import { ClientService } from './client/sherad/client.service';


@NgModule({
  declarations: [
    AppComponent, ClientComponent, ClientTaskComponent, ClientService
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    HttpClientModule,
    FormsModule,
    FormBuilder,.........///Remove this
    FormGroup,...........///Remove this
    FormControl..........///Remove this
    ReactiveFormsModule ..........//Add this
], 
providers: [], 
bootstrap: [AppComponent] 
}) 

export class AppModule { }

并将其导入您的 .ts

import {FormBuilder, FormControl, FormGroup, Validators, FormsModule} from '@angular/forms';

永远记得在

@NgModule
(

声明仅包含组件

imports 仅包含modules

providers 仅包含services
