javascript：时间戳格式化

	// 时间戳转yy-mm-dd
export const timeFormat = (date, formatStr) => {
    if (date.toString().indexOf('.') > -1 || date.toString().indexOf('-') > 0 || date.toString().indexOf('/') > -1) {
      return date;
    }
    if (typeof date === 'number' || typeof date === 'string') {
      date = new Date(date * 1000);
    }
    let str = formatStr;
    str=str.replace(/yyyy|YYYY/, date.getFullYear());
    str=str.replace(/MM/, date.getMonth()+1>9?(date.getMonth()+1).toString():'0' + (date.getMonth()+1));
    str=str.replace(/dd|DD/, date.getDate()>9?date.getDate().toString():'0' + date.getDate());
    str=str.replace(/hh|HH/, date.getHours()>9?date.getHours().toString():'0' + date.getHours());
    str=str.replace(/mm/, date.getMinutes()>9?date.getMinutes().toString():'0' + date.getMinutes());
    str=str.replace(/ss/, date.getSeconds()>9?date.getSeconds().toString():'0' + date.getSeconds());
    return str;
};
