wchat小程序中的日期格式化

1.微信自带的

const format=require("../../utils/util.js");
var date = format.formatTime(this.data.expirationDate,'Y/M/D');

 

2.把2017/8/1 0:00:00转换成 2017-08-01

1.util.js里面的代码

const formatNumber = n => {
    n = n.toString()
    return n[1] ? n : '0' + n
}
/**
 * 时间戳转化为年 月 日 时 分 秒
 * ts: 传入时间戳
 * format：返回格式，支持自定义，但参数必须与formateArr里保持一致
*/
function tsFormatTime(timestamp, format) {

    const formateArr = ['Y', 'M', 'D', 'h', 'm', 's'];
    let returnArr = [];

    let date = new Date(timestamp);
    let year = date.getFullYear()
    let month = date.getMonth() + 1
    let day = date.getDate()
    let hour = date.getHours()
    let minute = date.getMinutes()
    let second = date.getSeconds()
    returnArr.push(year, month, day, hour, minute, second);

    returnArr = returnArr.map(formatNumber);

    for (var i in returnArr) {
        format = format.replace(formateArr[i], returnArr[i]);
    }
    return format;

}

module.exports = {
    tsFormatTime: tsFormatTime
}

2.var util = require('../../utils/util.js');  

3.把日期转换成时间戳
     formatTimeStamp:function(data){
        return Date.parse(new Date(`${data}`)) || Date.parse(new Date(`${data.replace(/-/g, '/')}`))
    },


4. var date = this.formatTimeStamp(curUserInfor.BIRTHDAY);
     var newDate = util.tsFormatTime(date, 'Y-M-D');
