问题描述

下面是我的对象数组的一个示例，应该按名称对它们进行排序. js常规排序如下所示，但是我的目标是按数值排序，例如:"1 ex，2 ex，3 ex，4 ex，11 ex ..".有人可以帮我实现这一目标吗?

Below is an example of my array of objects and I am supposed to sort these by name. The js normal sorting sorts as shown below, however my target is to sort by the numeric value, eg: "1 ex, 2 ex, 3 ex, 4 ex, 11 ex ..". Could someone help me how to achieve this?

[{id: 588, name: "1 ex"}
{id: 592, name: "11 ex"}
{id: 607, name: "2 ex"}
{id: 580, name: "3 ex"}
{id: 596, name: "4 ex"}]

推荐答案

您必须将parse函数包括在您的compare函数中，如下所示:

You have to include the parse function in your compare function like this:

var compare = function(a, b) {
  return parseInt(a.name) - parseInt(b.name);
}

console.log(x.sort(compare));
