js获取年月日时分秒

var date =new Date()

var y =date.getFullYear();

var m =date.getMonth() +1;

m =m <10 ? ('0' +m) :m;

var d =date.getDate();

d =d <10 ? ('0' +d) :d;

var h =date.getHours();

h=h <10 ? ('0' +h) :h;

var minute =date.getMinutes();

minute =minute <10 ? ('0' +minute) :minute;

var second=date.getSeconds();

second=second <10 ? ('0' +second) :second;

var crossTime =y +'/' +m +'/' +d+' '+h+':'+minute+':'+second;

crossTime =new Date(crossTime).getTime();
