如何按多个字段对对象数组进行排序? [英] How to sort an array of objects by multiple fields?

问题描述

从这个原始问题，我将如何对多个字段应用排序?

From this original question, how would I apply a sort on multiple fields?

使用这种稍微调整的结构，我将如何对城市(升序)和那么价格(降序)?

Using this slightly adapted structure, how would I sort city (ascending) & then price (descending)?

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":"6",
     "city":"Dallas",
     "state":"TX",
     "zip":"75000",
     "price":"556699"},
    {"h_id":"5",
     "city":"New York",
     "state":"NY",
     "zip":"00010",
     "price":"962500"}
    ];

我喜欢这个事实而不是给出了答案这提供了一个通用的方法.在我计划使用此代码的地方，我必须对日期和其他内容进行排序.为对象准备"的能力似乎很方便，如果不是有点麻烦.

I liked the fact than an answer was given which provided a general approach. Where I plan to use this code, I will have to sort dates as well as other things. The ability to "prime" the object seemed handy, if not a little cumbersome.

我尝试构建这个 回答一个不错的通用示例，但我运气不佳.

I've tried to build this answer into a nice generic example, but I'm not having much luck.

推荐答案

您可以使用链式排序方法，通过取值的增量直到达到不等于零的值.

You could use a chained sorting approach by taking the delta of values until it reaches a value not equal to zero.

var data = [{ 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: "6", city: "Dallas", state: "TX", zip: "75000", price: "556699" }, { h_id: "5", city: "New York", state: "NY", zip: "00010", price: "962500" }];

data.sort(function (a, b) {
    return a.city.localeCompare(b.city) || b.price - a.price;
});

console.log(data);

.as-console-wrapper { max-height: 100% !important; top: 0; }

或者，使用 es6，简单地:

Or, using es6, simply:

data.sort((a, b) => a.city.localeCompare(b.city) || b.price - a.price);
