Angular2 - Enter Key 执行表单上的第一个(单击)功能 [英] Angular2 - Enter Key executes first (click) function present on the form

问题描述

我不知道为什么每次在输入元素中按 ENTER 键应用程序执行它在 html 中找到的第一个函数.

我该如何预防?

我尝试使用 (keyup.enter) 事件进行一些测试，但它首先执行第一个 (click) 函数，然后执行 (keyup.enter) 函数...

这是代码:

html 表单

<p-dialog modal=modal"[(可见)]=displayModal_Duplicate"；宽度=300"响应=真"><p-header>复制Offerta</p-header><div class="form-group"><label for=idCustomer">Selezionare il Cliente</label><!--<input formControlName="idCustomer";类型=文本"class=表单控制输入-sm"id=idCustomer"占位符="需要自动对焦>--><select id="idCustomer_dup";类=表单控制"formControlName="idCustomer_dup";[(ngModel)]=idCustomer_dup"><option [value]="c.idCustomer";*ngFor="let c of listCustomers">{{c.businessName}}</选项></选择>

<p-页脚><div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix"><button class="btn btn-primary btn-space";(click)=do_OffertDuplicate()">

</p-footer></p-对话框>

......

component.ts 函数

 do_OffertDuplicate() {如果(this.idCustomer_dup == null){警报(Selezionare il Cliente")；返回;}this.offertService.Duplicate(0, this.offert.idOffert, this.idCustomer_dup).subscribe(资源=>{this.displayModal_Duplicate = false;alert("OFFERTA DUPPLICATA ("+res.idOffert+")");this.router.navigate(['OffertDetail', res.idOffert]);});}检查密钥(){警报();}

感谢支持！

解决方案

如果按钮上没有类型，它会被视为提交按钮，因此它可能正在尝试提交表单.尝试将类型添加到按钮标签:

<按钮...类型=按钮"...>

I don't know why each time I press ENTER key in an input element the application execute the first function it finds in the html .

How Can I prevent it ?

I tried to make some test with (keyup.enter) event but it first execute the first (click) function, then the the (keyup.enter) function...

This is the code:

html form

<form role="form" [formGroup]="FormOffertDetail" (keyup.enter)="checkKey()">

<p-dialog modal="modal" [(visible)]="displayModal_Duplicate" width="300" responsive="true">
  <p-header>
    Dupplica Offerta
  </p-header>

  <div class="form-group">
    <label for="idCustomer">Selezionare il Cliente</label>
    <!--<input formControlName="idCustomer" type="text" class="form-control input-sm" id="idCustomer" placeholder="" required autofocus>-->
    <select id="idCustomer_dup" class="form-control" formControlName="idCustomer_dup" [(ngModel)]="idCustomer_dup">
                    <option [value]="c.idCustomer" *ngFor="let c of listCustomers">
                      {{c.businessName}}
                    </option>
                    </select>
  </div>

  <p-footer>
    <div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix">
      <button class="btn btn-primary btn-space" (click)="do_OffertDuplicate()"><i class="fa fa-copy fa-lg" aria-hidden="true"></i> Dupplica</button>
      <button class="btn btn-danger btn-space" (click)="displayModal_Duplicate=false"><i class="fa fa-trash-o fa-lg" aria-hidden="true"></i> Annulla</button>
    </div>
  </p-footer>
</p-dialog>

......

component.ts functions

 do_OffertDuplicate() {
    if (this.idCustomer_dup == null) {
      alert("Selezionare il Cliente");
      return;
    }

    this.offertService.Duplicate(0, this.offert.idOffert, this.idCustomer_dup).subscribe(
      res => {
        this.displayModal_Duplicate = false;
        alert("OFFERTA DUPPLICATA ( "+res.idOffert+" )");
        this.router.navigate(['OffertDetail', res.idOffert]);
        
      }
    );

  }

checkKey()
{
  alert();
}

Thanks to support!

解决方案

Without a type on the button, it is seen as a submit button so it may be attempting to submit the form. Try adding the type to the button tag:

<button
  ...
  type="button"
  ...
>
