來自jsonp的數據

Question

我怎麼做（用Jquery）從這個json結果中獲取特定值？例如用於電子郵件

[ 
{ 
    address: "", 
    province: "", 
    firstName: "Anna", 
    email: "anna@example.org", 
    postalCode: "", 
    key: "135", 
    type: "technical", 
    description: "", 
    isPrimaryContact: true, 
    phone: "", 
    country: "", 
    city: "", 
    salutation: "", 
    position: " Projects Leader, Academic Systems", 
    lastName: "" 
} 
] 

我使用$ .ajax（），來自不同服務器中的json。

如果你有一個JSON對象，你會簡單地使用：

var email = data.email; 

這是一個完整的，縮短例如：

var data = { 
    address: "", 
    province: "", 
    firstName: "Anna", 
    email: "anna@example.org" 
}; 

alert(data.email); 

如果數據真的是一個數組，你需要用途：

alert(data[0].email); 

類似縮短的例子：

var data = [{ 
    address: "", 
    province: "", 
    firstName: "Anna", 
    email: "anna@example.org" 
}]; 

alert(data[0].email);
