获取当前时间精确到毫秒

var myDate = new Date();var y=myDate.getFullYear(); //获取完整的年份(4位,1970-????)var m=myDate.getMonth()+1; //获取当前月份(0-11,0代表1月)var d=myDate.getDate(); //获取当前日(1-31)var t=myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)var h=myDate.getHours(); //获取当前小时数(0-23)var min=myDate.getMinutes();//获取当前分钟数(0-59)var s=myDate.getSeconds();//获取当前秒数(0-59)var ms=myDate.getMilliseconds(); //获取当前毫秒数(0-999)if (m >= 1 && m <= 9) {m = "0" + m;}if (d >= 0 && d <= 9) {d = "0" + d;}if (h >= 0 && h <= 9) {h = "0" + h;}if (min >= 0 && min <= 9) {min = "0" + min;}if (s >= 0 && s <= 9) {s = "0" + s;}var fh='-';var fh2=':'var tolocaltime=y+fh+m+fh+d+' '+h+fh2+min+fh2+s+fh2+ms;//当前时间
