Question

我想声明这个对象的数组，我怎么能在javascript中做到这一点？

student[0].name  
student[0].age
student[0].id

student[1].name  
student[1].age
student[1].id

有人可以提出建议吗？

Answer 1

像这样：

var students = [{ name: 'foo', age: 5, id: 1 }, { name: 'bar', age: 6, id: 2 }];

Answer 2

另一种方式：

var Student = function(n, a, i) {
    this.name = n;
    this.age = a;
    this.id = i;
};

var students = [];
students.push(new Student('foo', 12, 1));
students.push(new Student('bar', 13, 2));
students.push(new Student('baz', 14, 3));

console.log(students[0].name);
console.log(students[2].age);
console.log(students[1].id);

首先声明一个对象

这不需要student.js你可以在同一个文件上写对象。

var newStudent = new Object(); //Declare object

newStudent.name="foo";
newStudent.age=20;
newStudent.id=01

//declare array
var student = new Array();
student.push(newStudent);

//later loop array and you can read with
student[0].age
