React.js 中的 Bootstrap 模式

javascript

我需要通过单击 Bootstrap 导航栏和其他地方的按钮来打开 Bootstrap Modal（以显示组件实例的数据，即提供“编辑”功能），但我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">

                    <ul className="nav navbar-nav navbar-right">

                    </ul>
                </div>
            </nav>
        );
    }
});

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

    loadData: function() {
        $.ajax({

    }
});

欢迎对代码提出其他意见和改进。

  1. 避免在 React 中使用 jQuery：你目前
javascri复制代码class ScheduleEntryListItem extends React.Component {

    constructo
constructor(props) {


super(props);
        this.state = { showModal: false };
    }

    openModal = 

() => {


this.setState({ showModal: true });
    };

    closeModal = 
    };

    closeMo


() => {


this.setState({ showModal: false });
    };


    };

    ren


render() {


const { item } = this.props;

        con
const deadline = moment(item.deadline).format("MMM Do YYYY, h:mm A");

  1. 将数据传递给模态组件：不是直接访问 DOM 元素来获取模态的数据，而是将必要的数据作为 props 传递给组件ScheduleEntryModal。
  2. 组件命名一致性：确保 coModal和 ScheduleEntrScheduleEntryModal`组件
  3. 组件生命周期使用：componentWillUnmount在您当前Modal的
  4. 错误处理：确保 propScheduleEntryList组件的loadData方法。
  5. 可访问性：确保您的模式是

通过遵循这些建议并相应地更新代码，您可以提高可读性、可维护性
