在Fly中以角度x(2 4 5)创建表格并提交表格的最佳方法是什么?

问题描述

我有一个angular x(2 4 5)应用程序，并且我必须发布帖子以将其重定向到银行页面，以便用户可以付款.因此，我想在DOM中动态创建一个表单并将其发布.找不到最佳方法.循环和创建表单很容易，但是绘制后直接将其发布并不容易.

I have an angular x(2 4 5) app, and i must make a post redirect to a bank page, so the user can pay something. So, I want to create a form on the fly in my DOM and post it. Can't find the best way. It's easy to loop and create a form, but not easy to directly post it after drawing it.

预先感谢

推荐答案

您可以使用具有隐藏字段和ViewChild的表单来获取表单的引用，例如

You can use a form with the fields hidden and ViewChild to get the reference of the form, e.g.

@Component({
  selector: 'my-app',
  template: `
    <button (click)="sendData()">send</button>
    <form #externalForm method="post" action="http://url-comerce" target="_blank">
      <input type="hidden"  id="data1" name="data1" [ngModel]="comerceData.data1">
      <input type="hidden" id="data2" name="data2" [ngModel]="comerceData.data2" >
    </form>
  `,
})
export class HomeComponent {

  comerceData:any={}

  @ViewChild('externalForm') externalForm: ElementRef;

  constructor() { }

  sendData() {
      //fill the data to send
      this.comerceData={
         data1:"something",
         data2:"something more"
      }
      //Use a setTimeout. if not, the change of the data are not send
      setTimeout(()=>{
        this.externalForm.nativeElement.submit()
      }, 0);
  }
}
