角度2表单提交选择标记

标签: html forms angular submit

我尝试将带有角度2的表单发送到rest api,我的问题是我想给select标签命名一个标签值。

示例:

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:spanish: </label>
      <select class="form-control" name="note1" 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">english: </label>
      <select class="form-control" name="note2" 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:frensh: </label>
      <select class="form-control" name="note3" 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>

我希望选择1 的名称为西班牙语(标签1的值)

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);
  }

}

如果我给每个选择标签添加不同的名称,那么每件事都可以正常工作:

every select have name, instead of that name I want to show the label value of every select

每个选择都有名称,而不是我想要显示每个选择的标签值。

答案 0 :(得分:1)

LABELs are not form elements that can hold or send data. They are captions tied to form elements.

因此,标签不会随着提交的ngForm一起发送。

为什么不将标签值作为选择控件的名称:

<label for="select1" class="col-md-4 col-lg-4 col-sm-2 align form-control-label">Langues:spanish: </label>
<select class="form-control" name="spanish" id="select1" ngModel>
    <option>1</option>
    <option>2</option>
    <option>3</option>
    <option>4</option>
    <option>5</option>
</select>

像这样你会得到你想要的结果:

result

** 要解决您的注释,您始终可以将标签文本保留在组件中的数组中,如:

labelsName = [{select1: "your 15 words label"}, {select2: "another label"}]

然后,当您收到提交时,将每个选择器的名称与数组上的键映射以获取标签。
