Javascript - 按 2 个属性对对象数组进行排序 [英] Javascript - Sort Array of objects by 2 Properties

问题描述

我想按 2 个不同的属性对一组对象进行排序.

I want to sort an array of objects by 2 different properties.

这些是我的对象

array = [{ resVal: "25FA15", resFlow: 49, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 1.5 },
 { resVal: "25FA2", resFlow: 52, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 2 },
{ resVal: "45FA2", resFlow: 53, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 },
{ resVal: "35FA2", resFlow: 59, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 }]

我想按较高的resFlow"值对数组进行排序，但具有最低的resHP"值.

I want to sort the array by the higher "resFlow" value, but with the lowest "resHP" value.

我想这样放置我的数组:

I want to put my array like this:

array = [{ resVal: "25FA15", resFlow: 49, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 1.5 },
{ resVal: "35FA2", resFlow: 59, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 },
{ resVal: "45FA2", resFlow: 53, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 },
 { resVal: "25FA2", resFlow: 52, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 2 }]

希望有人能帮助我.

谢谢.

推荐答案

您可以对键的指定顺序及其排序顺序使用链式方法.

You could use a chained approach for a specified order of keys and their sort order.

数组按属性排序

• resHP，升序和
• resFlow，降序.

• resHP, ascending and
• resFlow, descending.

它用于计算增量，这反映了两个对象的关系.如果值为零，则两个值相等，并计算并返回下一个增量.

It works with calculating the delta and this reflects the relation of the two objects. If the value is zero, then the two values are equal and the next delta is calculated and returned.

var array = [{ resVal: "25FA15", resFlow: 49, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 1.5 }, { resVal: "25FA2", resFlow: 52, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 2 }, { resVal: "45FA2", resFlow: 53, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 }, { resVal: "35FA2", resFlow: 59, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 }];

array.sort(function (a, b) {
    return a.resHP - b.resHP || b.resFlow - a.resFlow;
});

console.log(array);

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