反应 - 防止表单提交 [英] React - Preventing Form Submission
问题描述
我一直在试验React。在我的经历中,我正在使用 Reactstrap框架。当我点击一个按钮时,我注意到HTML表单提交了。有没有办法在单击按钮时阻止表单提交?
I've been experimenting with React. In my experiement, I'm using the Reactstrap framework.When I click a button, I've noticed that the HTML form submits. Is there a way to prevent form submission when a button is clicked?
我已经重新创建了我的问题这里一>。我的表单很基本,看起来像这样:
I've recreated my issue here. My form is pretty basic and looks like this:
<Form>
<h3>Buttons</h3>
<p>
<Button color="primary" onClick={this.onTestClick}>primary</Button>
</p>
</Form>
我缺少什么?
推荐答案
我认为首先值得注意的是,如果没有javascript(普通html),单击时会提交
或表单
元素<输入类型= 提交 值= 提交表单 > <按钮>提交形成太< /按钮>
。在javascript中,您可以通过使用事件处理程序并在按钮单击或表单提交时调用 e.preventDefault()
来防止这种情况。 e
是传递给事件处理程序的事件对象。使用react,两个相关的事件处理程序可以通过 onSubmit
形式获得,另一个通过 onClick
。
I think it's first worth noting that without javascript (plain html), the form
element submits when clicking either the <input type="submit" value="submit form">
or <button>submits form too</button>
. In javascript you can prevent that by using an event handler and calling e.preventDefault()
on button click, or form submit. e
is the event object passed into the event handler. With react, the two relevant event handlers are available via the form as onSubmit
, and the other on the button via onClick
.
