Angular 2:表单提交取消，因为表单未连接 [英] Angular 2: Form submission canceled because the form is not connected

问题描述

我有一个包含表单的模态，当模态被销毁时，我在控制台中收到以下错误:

I have a modal that contains a form, when the modal is destroyed I get the following error in the console:

表单提交被取消，因为表单未连接

Form submission canceled because the form is not connected

模态被添加到 元素中，该元素是我的顶级元素 的直接子元素.

The modal is added to a <modal-placeholder> element which is a direct child to <app-root>, my top level element.

从 DOM 中删除表单并在 Angular 2 中消除此错误的正确方法是什么?我目前使用 componentRef.destroy();

What's the correct way to removing a form from the DOM and getting rid of this error in Angular 2? I currently use componentRef.destroy();

推荐答案

发生这种情况可能还有其他原因，但在我的情况下，我有一个按钮被浏览器解释为提交按钮，因此表单在单击按钮导致错误.添加 type="button" 解决了这个问题.完整元素:

There might be other reasons this occurs but in my case I had a button that was interpreted by the browser as a submit button and hence the form was submitted when the button was clicked causing the error. Adding type="button" fixed the issue. Full element:

    <button type="button" (click)="submitForm()">
