我目前正在尝试从我的表单中的表格提交同步生成的内容。我正在使用 Angular 6 生成表单,但对于我的一生,我无法弄清楚如何在 FormGroup 声明中表示表单的动态内容。
import { Component } from '@angular/core';
import { FormControl, FormGroup, Validators } from "@angular/forms";
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
accountDetails = [{
id: 1,
name: 'Account 1',
amountHeld: 5453.7,
amountToTransfer: 0
},
{
id: 2,
name: 'Account 2',
amountHeld: 5644.7,
amountToTransfer: 0
},
{
id: 3,
name: 'Account 3',
amountHeld: 42465.7,
amountToTransfer: 0
}
,{
id: 4,
name: 'Account 4',
amountHeld: 1434.7,
amountToTransfer: 0
}
]
transferDetailsForm = new FormGroup({
transferType: new FormControl("", [Validators.required]),
});
}
<form name="transferDetailsForm" [formGroup]="transferDetailsForm">
<div class="row">
<div class="form-group">
<label class="required">Choose category of transfer </label>
<div id="rbTradeCategorySelect" class="form-group" style="padding-left: 20px;">
<label for="rbMove" class="radio-inline">
<input type="radio" value="SaleOrGift" (change)="changeTransferCategory($event)" formControlName="transferType" click-capture />
Sale or gift
</label>
<label for="rbLease" class="radio-inline">
<input type="radio" radio value="Lease" (change)="changeTransferCategory($event)" formControlName="transferType" click-capture />
Lease
</label>
</div>
</div>
</div>
<table>
<thead>
<th>Account Name </th>
<th>Account Balance</th>
<th>Amount to Transfer</th>
</thead>
<tbody>
<tr *ngFor='let a of accountDetails'>
<td>{{a.name}}</td>
<td>{{a.amountHeld}}</td>
<td>
<input type="hidden" placeholder="{{a.id}}"/>
<input type="text" placeholder="{{a.amountToTransfer}}"/>
</td>
</tr>
</tbody>
</table>
<button id="btnSubmit" class="btn btn-success btn-lg" (ngSubmit)="transferDetailsForm.valid"
click-capture>
Submit
</button>
</form>
我创建了以下表格模型,希望有人可以帮助我。
