Angular 2：提交时将所有表单字段放在json对象中

Question

我有一个表单有多个字段，我想在提交时检索数据。

这是component.html：

<div class="ui raised segment">
  <h2 class="ui header">Demo Form: Sku</h2>
  <form #f="ngForm"
        (ngSubmit)="onSubmit(f.value)"
        class="ui form">

    <div class="field">
      <label for="skuInput">SKU</label>
      <input type="text"
             id="skuInput"
             placeholder="SKU"
             name="sku" ngModel>
    </div>
    <div class="field">
      <label for="select1" class="col-md-4 col-lg-4 col-sm-2 align form-control-label">Langues:français/anglais: </label>
      <select class="form-control" name="note" id="select1" ngModel>
        <option>1</option>
        <option>2</option>
        <option>3</option>
        <option>4</option>
        <option>5</option>
      </select>

      <label for="select2" class="col-md-4 col-lg-4 col-sm-2 align form-control-label">Langues:français/anglais: </label>
      <select class="form-control" name="note" id="select2" ngModel>
        <option>1</option>
        <option>2</option>
        <option>3</option>
        <option>4</option>
        <option>5</option>
      </select>

      <label for="select3" class="col-md-4 col-lg-4 col-sm-2 align form-control-label">Langues:français/anglais: </label>
      <select class="form-control" name="note" id="select3" ngModel>
        <option>1</option>
        <option>2</option>
        <option>3</option>
        <option>4</option>
        <option>5</option>
      </select>

    </div>

    <button type="submit" class="ui button">Submit</button>
  </form>
</div>

这里是component.ts：

import {Component, OnInit} from '@angular/core';

@Component({
  selector: 'app-post-history',
  templateUrl: './post-history.component.html',
  styleUrls: ['./post-history.component.css']
})
export class PostHistoryComponent implements OnInit {

  constructor() {
  }

  ngOnInit() {
  }

  onSubmit(form: any): void {
    console.log('you submitted value:', form);
  }

}

在控制台日志中它只显示文本输入，只显示一个选择值！

您的所有select元素都具有相同的{note} name属性。您可以更改它们以匹配元素的ID：

<select class="form-control" name="note1" id="select1" ngModel>

<select class="form-control" name="note2" id="select2" ngModel>
