簡單介紹JSON是什麼玩意兒？ ( Short introduction to JSON )

若您覺得文章寫得不錯，請點選文章上的廣告，來支持小編，謝謝。

JSON的全名為JavaScript Object Notation，提供便利又易懂方法來儲存資訊，下面就是一個簡單的例子：

	var holan = {
	"age" : "3x",
	"hometown" : "Yunlin, Taiwan",
	"gender" : "male"
	};

JSON的語法是以"name": "value"來運作，上述例子建立了一個holan的變數，儲存了age、hometown、gender三項資訊。
下面是陣列的例子：

	var holanfamily = [{
	"name" : "Holan",
	"age" : "3x",
	"gender" : "male"
	},
	{
	"name" : "Cat",
	"age" : "3",
	"gender" : "male"
	},
	{
	"name" : "Dog",
	"age" : "4",
	"gender" : "female"
	}];

	document.write(holanfamily[2].name); // 輸出 Cat
	document.write(holanfamily[1].gender); // 輸出 male

有時會需要驗證JSON的語法，此網頁：http://jsonlint.com/可幫助我們做到這件事。
