Question

我想使用 moment.js 检查当前日期在从07-11-2017到05-01-2018之间的日期之间是否有效。< / p>

任何帮助?? 怎么做？

我有以下代码：

import React, {Component} from 'react';
import moment from 'moment';

class Dates extends Component {
  constructor() {
    super();
    this.state = {
      dateNow: moment(),
      availability:''
    }
  }
  componentDidMount() {
    let startdate = moment("17-11-2017");
    let enddate = moment("05-01-2018");

    this.setState({
      availability: 'Yes'
    });
  }
  render() {
    return(
       <div>
         <div>{this.state.dateNow}</div>
         <table>
           <tr>
             <td>Available from 7th November,2017 to 5th January,2018?</td> 
             <td>{this.state.availability}</td>
           </tr>
          </table>
       </div>
    );
  }
}
export default Dates;

Answer 1

使用isBetween检查可用性，如

moment('22-11-2017').isBetween('17-11-2017', '05-01-2018');

如果条件为真，则方法返回true，否则为false。

首先将其转换为有效的日期对象

let date  = moment("22-11-2017", "DD-MM-YYYY")
let startdate = moment("17-11-2017","DD-MM-YYYY");
let enddate = moment("05-01-2018","DD-MM-YYYY");

然后转换日期格式的日期使用

var a = date.toDate();b= startdate.toDate(),c=enddate.toDate();

然后使用简单的if条件

 if (a.getTime() >=b.getTime() && a.getTime() <=c.getTime())
     console.log('do your stuff')
    else 
    console.log('sorry timeout')

您也可以使用此

date.isBetween(startdate,enddate)

片刻Js日期比较
