Js中将Long转换成日期格式的实现方法

datetimeFormat(longTypeDate); 

dateFormat(longTypeDate); 

    /* * 时间格式化工具 
 * 把Long类型的1527672756454日期还原yyyy-MM-dd 00:00:00格式日期 
 */

 dateTypeDate += "-" + getMonth(date); //月  
 dateTypeDate += "-" + getDay(date); //日  
 dateTypeDate += " " + getHours(date); //时  
 dateTypeDate += ":" + getMinutes(date);  //分 
 dateTypeDate += ":" + getSeconds(date);  //分 
 return dateTypeDate;
