javascript - React.js 中的 Bootstrap 模式

Question

我需要通过点击 Bootstrap 导航栏和其他地方的按钮来打开 Bootstrap Modal(显示组件实例的数据，即提供“编辑”功能)，但我不不知道如何实现这一点。这是我的代码:

编辑:代码已更新。

ApplicationContainer = React.createClass({
    render: function() {
        return (
            <div className="container-fluid">
            <NavBar />
                <div className="row">
                    <div className="col-md-2">
                        <ScheduleEntryList />
                    </div>
                    <div className="col-md-10">
                    </div>
                </div>
                <ScheduleEntryModal />
            </div>
        );
    }
});

NavBar = React.createClass({
    render: function() {
        return (
            <nav className="navbar navbar-default navbar-fixed-top">
                <div className="container-fluid">
                    <div className="navbar-header">
                        <a className="navbar-brand" href="#">
                            <span className="glyphicon glyphicon-eye-open"></span>
                        </a>
                    </div>
                    <form className="navbar-form navbar-left">
                        <button className="btn btn-primary" type="button" data-toggle="modal" data-target="#scheduleentry-modal">
                            <span className="glyphicon glyphicon-plus">
                            </span>
                        </button>
                    </form>
                    <ul className="nav navbar-nav navbar-right">
                        <li><a href="#"><span className="glyphicon glyphicon-user"></span> Username</a></li>
                    </ul>
                </div>
            </nav>
        );
    }
});

ScheduleEntryList = React.createClass({
    getInitialState: function() {
        return {data: []}
    },

    loadData: function() {
        $.ajax({

            dataType: "json",

            error: function(xhr, status, error) {
                console.error("/api/tasks", status, error.toString());
            }.bind(this)
        });

    componentWillMount: function() {
        this.loadData();
        setInterval(this.loadData, 20000);
    },

    render: function() {
        items = this.state.data.map(function(item) {

我最近正在寻找一个很好的解决方案，而不是将 React-Bootstrap 添加到我的项目中(因为 Bootstrap 4 即将发布)。

这是我的解决方案:https://jsfiddle.net/16j1se1q/1/

let Modal = React.createClass({
    componentDidMount(){
        $(this.getDOMNode()).modal('show');
        $(this.getDOMNode()).on('hidden.bs.modal', this.props.handleHideModal);
    },
    render(){
        return (
          <div className="modal fade">
            <div className="modal-dialog">
              <div className="modal-content">
                <div className="modal-header">
                  <button type="button" className="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                  <h4 className="modal-title">Modal title</h4>
                </div>
                <div className="modal-body">
                  <p>One fine body&hellip;</p>
                </div>
                <div className="modal-footer">
                  <button type="button" className="btn btn-default" data-dismiss="modal">Close</button>
                  <button type="button" className="btn btn-primary">Save changes</button>
                </div>
              </div>
            </div>
          </div>
        )
    },
    propTypes:{
        handleHideModal: React.PropTypes.func.isRequired
    }
});



let App = React.createClass({
    getInitialState(){
        return {view: {showModal: false}}
    },
    handleHideModal(){
        this.setState({view: {showModal: false}})
    },
    handleShowModal(){
        this.setState({view: {showModal: true}})
    },
    render(){
    return(
        <div className="row">
            <button className="btn btn-default btn-block" onClick={this.handleShowModal}>Open Modal</button>
            {this.state.view.showModal ? <Modal handleHideModal={this.handleHideModal}/> : null}
        </div>
    );
  }
});

React.render(
   <App />,
    document.getElementById('container')
);

主要思想是仅在要显示时(在 App 组件渲染函数中)将模态组件渲染到 React DOM 中。我保留了一些“ View ”状态，指示模态当前是否显示。

“componentDidMount”和“componentWillUnmount”回调通过 Bootstrap javascript 函数隐藏或显示模态(一旦它被渲染到 React DOM 中)。

我认为这个解决方案很好地遵循了 React 的精神，但欢迎提出建议!
