通过按Enter无需提交按钮即可提交angular2提交表单

问题描述：

是否可以提交没有提交按钮的表单(通过按Enter键) 例子:

Is it possible to submit a form that does not have submit button (by pressing enter) example :

<form [ngFormModel]="xxx" (ngSubmit)="xxxx()">
  <input [(ngModel)]="lxxR"   ngControl="xxxxx"/>
</form

答

也许您将 keypress 或 keydown 添加到输入字段并将事件分配给点击进入时将执行提交的功能

maybe you add keypress or keydown to the input fields and assign the event to function that will do the submit when enter is clicked

您的模板看起来像这样

<form (keydown)="keyDownFunction($event)">
  <input type="text" />
</form

您在类中的功能将如下所示

And you function inside the your class would look like this

keyDownFunction(event) {
  if (event.keyCode === 13) {
    alert('you just pressed the enter key');
    // rest of your code
  }
}
