Javascript：從軍事轉換到標準時間

我想把這個軍事時鐘轉換爲標準時間。我是新手（只是學習）如何編碼電腦，不知道該怎麼做。網站，資源，想法將不勝感激。謝謝！Javascript：從軍事轉換到標準時間

很好，不斷的學習，谷歌搜索是很好的，例如「JavaScript的轉換軍事時間「，w3school（w3fool海報噓）。有很多地方需要學習。我會先嚐試谷歌搜索和JavaScript的基礎知識，因爲這是需要較少的物理資源 – alexmac

我應該補充說，在這個網站上，你需要問一些更具體的問題，並似乎已經做了你的搜索答案之前先問但既然你的「新」，我認爲我會幫助，而不是投票 – alexmac

行後：

hours = format(hours);

您應該能夠使用的東西，如：

if (hours > 12) { 
    hours = hours - 12; 
}
