React.js:以编程方式提交表单不会触发onSubmit事件 [英] React.js: submit form programmatically does not trigger onSubmit event

问题描述

我想在单击链接后提交一个React表单.

I want to submit a React form after a click on a link.

为此，如果单击链接，我需要以编程方式提交表单.

To do so I need to submit the form programmatically if the link is clicked.

我的问题是:提交表单后未触发onSubmit处理程序.

my problem is : onSubmit handler is not being fired after the form submit .

这是我为此目的而编写的代码:

Here is a code snipped that I made for this purpose:

var MyForm = React.createClass({
  handleSubmit: function(e){
    console.log('Form submited');
     e.preventDefault();
  },
  submitForm : function(e){
    this.refs.formToSubmit.submit();
  },
  render: function() {
    return (
    <form ref="formToSubmit" onSubmit={this.handleSubmit}>
    <input name='myInput'/>
    <a onClick={this.submitForm}>Validate</a>
    </form>);
  }
});

ReactDOM.render(
  <MyForm name="World" />,
  document.getElementById('container')
);

handleSubmit不会被调用，并且将执行默认行为(正在提交表单). 这是ReactJs错误还是正常行为? 有没有一种方法可以调用onSubmit处理程序?

The handleSubmit is not invoked and the default behavior is executed (the form being submitted). Is this a ReactJs bug or a normal behavior? Is there a way to get the onSubmit handler invoked ?

推荐答案

我在此方面取得了成功.单击后触发handleSubmit.希望这会有所帮助.

I have success with this. This triggers the handleSubmit upon clicking. Hope this helps.

<form
  onSubmit={this.handleSubmit}
  ref={ (ref) => { this.form = ref; } }
>
    <a onClick={ () => { this.form.dispatchEvent(new Event('submit')) } }>
        Validate
    </a>
</form>
