React 时间选择框架 react-datetime 介绍

1. 介绍

本文主要介绍react-datetime框架，一个可以方便选择日期时间的一个前端React框架。

2. 安装

npm install --save react-datetime

3. CSS 显示效果

按照他文档里来的显示效果是有点问题的，把下面的css文件复制到相应的组件css文件里。

.rdt {
  position: relative;
}
.rdtPicker {
  display: none;
  position: absolute;
  width: 250px;
  padding: 4px;

4. Demo

采用ES6语法

import Datetime from 'react-datetime';

class Example extends Component {
    constructor(props) {
        this.state = {
            startTime: new Date(),
            endTime: new Date(),
        };
        this.handleChangeStartTime = this.handleChangeStartTime.bind(this);
        this.handleChangeEndTime = this.handleChangeEndTime.bind(this);
    }

    handleChangeStartTime(event) {
        // console.log(event._d);
        this.setState({startTime: event._d});
    }

    handleChangeEndTime(event){
        // console.log(event._d);
        this.setState({endTime: event._d});
    }
    render() {
        return(
          <div>
            <Datetime value={this.state.startTime} onChange={this.handleChangeStartTime}/>
            <Datetime value={this.state.endTime} onChange={this.handleChangeEndTime}/>
          </div>
        );
    }

}
export default Example;
