对于这种情况，我建议从Submit事件中获取表单，并根据需要遍历其子表单元素。添加

name

refs

var ActivityForm = React.createClass({  handleSubmit: function(e) {    e.preventDefault();    var form = e.target;    // Use the standard [`HTMLFormElement.elements`][1] collection    //    // [1]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/elements    var content = form.elements['content'].value;    // do more things with other named form elements  },  render: function() {    return (      <div className="new-activity">        <h3>New Activity</h3>        <form onSubmit={this.handleSubmit}>          <textarea name='content' />          <br />          <label>Category</label>          <ActivityFormCategoryDropdown />          <br />          <input type="submit" value="Add Activity" />        </form>      </div>    );  }});
