javascript - 如何在javascript中创建对象列表

Question

        var employee =
        {
            Column1: null,
            Column2: null,

            create: function () {
                var obj = new Object();

                obj.Column1 = "";
                obj.Column2 = "";

                return obj;
            }
        };

在 C# 中，我会做这样的事情：

List<Employee> employees = new List<Employee>();

for (int i = 0; i < 10; i++)
{
    Employee emp = new Employee()
    {
        Column1 = "column 1 of emp" + i;
        Column2 = "column 2 of emp" + i;
    }
    employees.Add(emp);
}

我需要在javascript中做同样的事情。

Answer 1

创建对象数组的非常直接的方法。

var employees = [];

for (var i = 0; i < 10; i++) {
    employees.push({
        Column1: 'column 1 of emp' + i,
        Column2: 'column 1 of emp' + i
    });
}

Answer 2

这是一个老问题，但只是想为它做出贡献。我用过数组

function car(brand, color, year, price) {
    this.brand = brand;
    this.color = color;
    this.year = year;
    this.price = price;
}

var my = new Array();
my.push(new car("Ford", "Black", 2017, 15000));
my.push(new car("Hyundai", "Red", 2017, 17000));

document.getElementById('ford').value = my[0].price;
document.getElementById('hyundai').value = my[1].price;

Ford price: <input type="text" id='ford'/><br><br>
Hyndai price: <input type="text" id='hyundai'/>

Answer 3

var list = [
{ date: '12/1/2011', reading: 3, id: 20055 },
{ date: '13/1/2011', reading: 5, id: 20053 },
{ date: '14/1/2011', reading: 6, id: 45652 }
];

访问列表使用：

list[index].date
