用js将从后台得到的13位时间戳（毫秒数）转换为想要的日期格式

function formatterTime(time, fmt) {

      if(!time){ return ''; } if(typeof(time) == "object" || typeof(time) == "OBJECT") { var z = { M: time.getMonth() + 1, d: time.getDate(), h: time.getHours(), m: time.getMinutes(), s: time.getSeconds() }; fmt = fmt.replace(/(M+|d+|h+|m+|s+)/g, function(v) { return ((v.length > 1 ? "0" : "") + eval('z.' + v.slice(-1))).slice(-2); }); return fmt.replace(/(y+)/g, function(v) { return time.getFullYear().toString().slice(-v.length); }); }else if(typeof(time) == "number"){ var TIME = new Date( time) ; var z = { M: TIME.getMonth() + 1, d: TIME.getDate(), h: TIME.getHours(), m: TIME.getMinutes(), s: TIME.getSeconds() }; fmt = fmt.replace(/(M+|d+|h+|m+|s+)/g, function(v) { return ((v.length > 1 ? "0" : "") + eval('z.' + v.slice(-1))).slice(-2); }); return fmt.replace(/(y+)/g, function(v) { return TIME.getFullYear().toString().slice(-v.length); }); } else return time; } formatterTime(1565780223000 ,"yyyy-MM-dd hh:mm:ss")
