js高手时间毫秒转格式

//格式化时间

var formatDate = function(time, format){

var t = new Date(time);

var tf = function(i){return (i < 10 ? ‘0‘ : ‘‘) + i};

return format.replace(/yyyy|MM|dd|HH|mm|ss/g, function(a){

switch(a){

case ‘yyyy‘:

return tf(t.getFullYear());

break;

case ‘MM‘:

return tf(t.getMonth() + 1);

break;

case ‘mm‘:

return tf(t.getMinutes());

break;

case ‘dd‘:

return tf(t.getDate());

break;

case ‘HH‘:

return tf(t.getHours());

break;

case ‘ss‘:

return tf(t.getSeconds());

break;

}

})

}

console.log(formatDate(new Date().getTime(), ‘yyyy-MM-dd HH:mm:ss‘))
