[Javascript] 取得現在日期時間

先new一個Date物件, 再用它去取得現在日期和時間

要注意的是getMonth()取回來的月份是0-11, 所以還要自行加一

另外前面補0的方法可參照下面範例, 十分簡潔, 可以寫在一行裡面

轉自 http://stackoverflow.com/questions/8398897/how-to-get-current-date-in-jquery

Date() is not part of jQuery, it is one of JavaScript's features.

You can do it like that:

 var d = new Date(); 
 var month = d.getMonth()+1; 
 var day = d.getDate(); 

 var output = d.getFullYear() + '/' + 
 (month<10 ? '0' : '') + month + '/' + 
 (day<10 ? '0' : '') + day;

See this jsfiddle for a proof.

The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10 (meaning the strings will have one char instead of two). See this jsfiddle for comparison.
