javascript - 按属性值对对象数组进行排序(Sorting an array of objects by property values)

Question

I've got the following objects using AJAX and stored them in an array:

(我使用AJAX获得了以下对象并将它们存储在数组中：)

var homes = [
    {
        "h_id": "3",
        "city": "Dallas",
        "state": "TX",
        "zip": "75201",
        "price": "162500"
    }, {
        "h_id": "4",
        "city": "Bevery Hills",
        "state": "CA",
        "zip": "90210",
        "price": "319250"
    }, {
        "h_id": "5",
        "city": "New York",
        "state": "NY",
        "zip": "00010",
        "price": "962500"
    }
];

How do I create a function to sort the objects by the price property in ascending or descending order using JavaScript only?

(如何创建仅使用JavaScript 按 price属性按升序 或 降序对对象进行排序的函数？)

Answer 1

Sort homes by price in ascending order:

(按价格升序对房屋进行排序：)

homes.sort(function(a, b) {
    return parseFloat(a.price) - parseFloat(b.price);
});

Or after ES6 version:

(或在ES6版本之后：)

homes.sort((a, b) => parseFloat(a.price) - parseFloat(b.price));
