用JavaScript中的两个属性对对象数组进行排序
假设我们有一个像这样的对象数组-
const arr = [
{ 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 }
];我们需要编写一个JavaScript函数，该函数接受一个这样的对象数组。函数应基于两个不同的属性对该数组进行排序-
按较高的“resFlow”值排序，
但“resHP”值最低。
方法
我们对指定的键顺序及其排序顺序使用链式方法。
数组按属性排序-
resHP，升序和
resFlow，降序。
它可以计算增量，这反映了两个对象的关系。如果该值为零，则两个值相等，并计算并返回下一个增量。
示例
为此的代码将是-
const arr = [
{ 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 }
];
const sortByTwo = (arr = []) => {
arr.sort((a, b) => {
return a.resHP − b.resHP || b.resFlow − a.resFlow;
});
};
sortByTwo(arr);
console.log(arr);输出结果
控制台中的输出将是-
[
{
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
}
