按角度4中的回车键提交表格

Question

按Enter键需要提交下面角度4的表单是我的代码形式Action = ""不工作。我还尝试使用(keydown) = domonething(event)和(keydown.enter) = domonething(event)以下代码

keyDownFunction(event) {
    if (event.keyCode == 13) {
        this.submit();
    }
}

以下是我目前的代码

<form #f="ngForm" (ngSubmit)="f.form.valid && openModal(confirmationmodal)" novalidate action="">
    <div class="form-group form-row">
        <label class="col-form-label col-sm-4 col-md-4" for="name">Employee Name</label>
        <div class="col-sm-8 col-md-8">
            <span type="text" readonly class="form-control-plaintext" id="name">{{employeeDetails.EmployeeName}}</span>
        </div>
    </div>
    <div class="form-group form-row">
        <label class="col-form-label col-sm-4 col-md-4 " for="name">Manager Name</label>
        <div class="col-md-8  col-sm-8">
            <span type="text" readonly class="form-control-plaintext"
                id="manager">{{employeeDetails.ManagerName}}</span>
        </div>
    </div>
    <div class="form-group form-row">
        <label for="name" class="col-sm-4 col-md-4 col-form-label">Subject</label>
        <div class="col-md-8 col-sm-8">
            <span type="text" readonly class="form-control-plaintext" id="manager">{{subject}}</span>
        </div>
    </div>

    <button class="btn btn-success float-right" type="submit" id="submit">Submit</button>
</form>

Answer 1

在提交按钮中提供(keyup.enter)="yourFunction()"

Answer 2

这应该工作

(keydown)="keyDownFunction($event)

在打字稿中

  keyDownFunction(event) {
    if ( event.keyCode === 13) {
      // do your function
    }
  }

这对我有用。我想你在比赛前错过了$。

Answer 3

如果你想用按钮调用它，你可以这样做 -

<button type="button" (keyup.enter)="doSomething()" >Click Me!</button>

Answer 4

从您的表单标记我将删除action属性并将以下内容：

<form #f="ngForm" (ngSubmit)="f.form.valid && openModal(confirmationmodal)" novalidate (keydown.enter)="onEnterKeyDown($event)">

然后只需编写按键事件的功能：

onEnterKeyDown($event) {
  // here you can open your confirmation modal if the form is valid
}
