JS時間轉時間戳，時間戳轉時間。時間顯示模式。

// 時間轉為時間戳

function
date2timestamp(datetime) 
// 時間戳轉時間
function
timestamp2date(timestamp, mode) $/, ' ').replace(/年|月/g, "-").replace(/日/g, " ").replace(/上午/g, "").replace(/下午/g, "");
var date_arr = tt.split(" ");

if (minc >= 1) else
result = "剛剛";
return result;
}if (mode == 2) else 
if (parseint(timestamp) > parseint(b_date - 24 * 60 * 60) && parseint(timestamp) < parseint(e_date - 24 * 60 * 60)) 
// 顯示週幾

array("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
var day = new
date(date_arr[0]).getday();
return days[day];}}
