借助此篇博客,实现了须要的性能,特此记录一下:https://www.cnblogs.com/guojbing/p/10872867.html

假如有一个对象数组:

const arr1 = [    {buyerId: "1", name: "WW"},    {buyerId: "2", name: "RR"},    {buyerId: "3", name: "OO"},    {buyerId: "4", name: "ll"},    {buyerId: "5", name: "DD"},    {buyerId: "6", name: "SS"}]

另一对象数组为:

const arr2 = [    {buyerId: "4", totalPrice: "7.00"},    {buyerId: "3", totalPrice: "90.00"},    {buyerId: "2", totalPrice: "10.00"},    {buyerId: "6", totalPrice: "70.00"},    {buyerId: "1", totalPrice: "9.00"},    {buyerId: "5", totalPrice: "60.00"}]

当初心愿arr2依照arr的buyerId属性排序,并显示其价格。应该怎么做呢?
首先,提取出arr1中的buyerId到一个新的数组:

let curArr = [];arr1.find(item => {    curArr.push(item.buyerId)});

这样就获取到了数组:

接着,让arr2依照curArr的数据排放顺序排列:

let newArr = [];arr2.sort((a, b) => {    const prev = curArr.indexOf(a.buyerId);    const next = curArr.indexOf(b.buyerId);    return prev-next;});arr2.forEach(item => {    newArr.push(item)})

失去的后果为:

这样就失去了依照要求排列的新数组,如果要只显示价格,就把newArr数组中的totalPrice提取到新的数组中,即可显示。

以上,就是我想要分享给大家的,还有另一种简略点的,对象数组依据数组进行比拟的排序形式,具体的请看文章开始贴出的博客地址。
