在JS中我們可以直接定義一個(gè)對(duì)象：
復(fù)制代碼 代碼如下:
var obj={name:"藍(lán)色",age:10};

上面其實(shí)就是所謂的JSON了，我引用下別人的復(fù)雜點(diǎn)的例子：
復(fù)制代碼 代碼如下:
{ firstName: "Brett", lastName:"McLaughlin", email: "brett@jb51.NET" }

復(fù)制代碼 代碼如下:
{ people: [
{ firstName: "Brett", lastName:"McLaughlin", email: "brett@jb51.NET" },
{ firstName: "Jason", lastName:"Hunter", email: "jb51.NET" },
{ firstName: "Elliotte", lastName:"Harold", emai": "elharo@jb51.NET" }
]}
{ people1: [
{ firstName: "Brett", lastName:"McLaughlin", email: "brett@jb51.NET" },
{ firstName: "Jason", lastName:"Hunter", email: "jb51.NET" },
{ firstName: "Elliotte", lastName:"Harold", emai": "elharo@jb51.NET" }
],
people2: [
{ firstName: "Brett", lastName:"McLaughlin", email: "brett@jb51.NET" },
{ firstName: "Jason", lastName:"Hunter", email: "jb51.NET" },
{ firstName: "Elliotte", lastName:"Harold", emai": "elharo@jb51.NET" }
],
people3: [
{ firstName: "Brett", lastName:"McLaughlin", email: "brett@jb51.NET" },
{ firstName: "Jason", lastName:"Hunter", email: "jb51.NET" },
{ firstName: "Elliotte", lastName:"Harold", emai": "elharo@jb51.NET" }
]
}

2.后臺(tái)傳輸進(jìn)來(lái)的滿足JSON條件的文本格式化。
因?yàn)镴SON最大的用途是AJAX應(yīng)用，因此關(guān)鍵是怎樣把文本轉(zhuǎn)換成Javascript對(duì)象，假設(shè)我們請(qǐng)求回的文本為data，那么我們?nèi)缦陆馕觯?
復(fù)制代碼 代碼如下:
data=data.replace(//n | /r/g,"");
var obj=eval('('+data+')');

因?yàn)槲覀兒笈_(tái)輸出的時(shí)候會(huì)把空格和回車符也輸出，因此這里要用正則替換掉，然后用eval轉(zhuǎn)換成對(duì)象就可以調(diào)用了。

JavaScript技術(shù)：簡(jiǎn)明json介紹，轉(zhuǎn)載需保留來(lái)源！
