javascript如何定義對象數組

問題如下，已經完成單個對象的簡單應用，希望定義一個數組，能包含多個student。

 

代碼如下:

var student = new Object();
student.name = "Lanny";
student.age = "25";
student.location = "China";
var json = JSON.stringify(student);

 

方法一：

 

代碼如下:

var students = [];
students[students.length] = new Object();
students[students.length].name = "Lanny";
students[students.length].age = "25";
students[students.length].location = "China";
var json = JSON.stringify(students);

 

方法二：

 

代碼如下:

var student = new Object();
student.name = "Lanny";
student.age = "25";
student.location = "China";
students = (students || []).push(student);
var json = JSON.stringify(students);
