JavaScript Date常見錯誤

經常使用PHP mktime()的開發者在使用JavaScript new Date()的時候最常忘記的狀況就是 javascript的月份參數必須要 -1, 因為他的月份是從0開始代表1月份。

$year = 2018;
$month = 05;
$day = 31;
$h = "09";
$i = "10";
$s = "00";
echo mktime($h,$i,$s,$month,$day,$year);

var year = 2018;
var month = "05";
var day = 31;
var h = "09";
var i = "10";
var s = "00";

console.log(new Date(year, month-1, day, h, i, s));
