[英]how to create list of objects in javascript
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。
非常直接的方法来创建一个对象数组。
var employees = [];
for (var i = 0; i < 10; i++) {
employees.push({
Column1: 'column 1 of emp' + i,
Column2: 'column 1 of emp' + i
});
}
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 }
];
用于访问列表使用:
list[index].date
这是一个古老的问题,但只是想为此做出贡献。 我用了数组
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'/>
