Angular-以编程方式提交表单 [英] Angular - Submit a form programmatically

问题描述

Angular-以编程方式提交表单.

Angular - Submit a form programmatically.

我在HTML上有一个表单组，我希望组件通过post方法中的email字段提交表单的操作.而不是使用常规的提交按钮.

I have a form group on the HTML and I want the component to submit the form's action with an email field in a post method. Instead of using a normal submit button.

下面的testMethod从另一个按钮调用.在这种方法中，我要发布 testForm .它必须按照旧的方式发布，因为它需要采取措施.

Below's testMethod gets called from another button. In this method, I want to post the testForm. It has to be posted old school way as it needs an action.

这是我的HTML:

  <form
    [formGroup]="testGroup"
    [action]='actionLink'
    method='POST'
    #testForm>
     <input name='Email' type='hidden' [value]='currentUserEmail'>
  </form>

这是我的组件TS文件尝试:

  @ViewChild('testForm') testFormElement;

  public currentUserEmail: string = '';
  public testGroup = this.formBuilder.group({
    Email: ''
  });


  public testMethod(): void {

      // Below: This currently doesnt seem to do anything.
      this.testFormElement.ngSubmit.emit();
  }

推荐答案

您可以在表单中使用ngNoForm来删除ngForm处理并添加纯JavaScript处理程序.

You can use ngNoForm with your form to remove ngForm handling and to add plain javascript handler.

您可以按以下方式使用您的代码:

you can use your code as follows:

HTML文件.

  <form ngNoForm
    [formGroup]="testGroup"
    [action]='actionLink'
    method='POST'
    #testForm>
     <input name='Email' type='hidden' [value]='currentUserEmail'>
  </form>

Ts文件.

  @ViewChild('testForm') testFormElement;

  public currentUserEmail: string = '';
  public testGroup = this.formBuilder.group({
    Email: ''
  });

  constructor(formBuilder: FormBuilder) {
  }    

  public testMethod(): void {
      this.testFormElement.nativeElement.submit();
  }
