在React.js中设置onSubmit
问题描述:
在提交表单时,我正在尝试 doSomething()
而不是默认的帖子行为。
On submission of a form, I'm trying to doSomething()
instead of the default post behaviour.
显然在React中, onSubmit是表单支持的事件。但是,当我尝试以下代码时:
Apparently in React, onSubmit is a supported event for forms. However, when I try the following code:
var OnSubmitTest = React.createClass({
render: function() {
doSomething = function(){
alert('it works!');
}
return <form onSubmit={doSomething}>
<button>Click me</button>
</form>;
}
});
运行方法 doSomething()
,但此后,仍然执行默认的帖子行为。
The method doSomething()
is run, but thereafter, the default post behaviour is still carried out.
您可以在我的 jsfiddle 中进行测试。
You can test this in my jsfiddle.
我的问题:如何防止默认的帖子行为?
My question: How do I prevent the default post behaviour?
答
在 doSomething()
函数中,传递事件 e
并使用 e.preventDefault ()
。
In your doSomething()
function, pass in the event e
and use e.preventDefault()
.
doSomething = function (e) {
alert('it works!');
e.preventDefault();
}
