js数组排序处理?-灵析社区

元气满满才怪啊

let arr = [ {price: 5, userUid: 0, item_name: '测试3'}, {price: 20, userUid: 0, item_name: '测试2'}, {price: 23, userUid: 0, item_name: '测试1'}, {price: 39, userUid: 0, item_name: '测试2'}, {price: 43, userUid: 0, item_name: '测试1'}, {price: 55, userUid: 0, item_name: '测试3'}, {price: 66, userUid: 0, item_name: '测试2'}, {price: 72, userUid: 0, item_name: '测试3'}, {price: 82, userUid: 0, item_name: '测试3'}, {price: 97, userUid: 0, item_name: '测试3'}, ] let items = [ { id: 1, num: 2 } { id: 2, num: 3 } { id: 3, num: 5 } ] 根据items数组里面num的值去arr数组里面拿数据，按竖向排序 期望得到数据格式： ![](https://wmprod.oss-cn-shanghai.aliyuncs.com/c/user/20240916/0f9e8b987dd17c2c29f7029453893252.png) let result= [ [{price: 5, userUid: 0, item_name: '测试3'},{price: 39, userUid: 0, item_name: '测试2'},] [{price: 20, userUid: 0, item_name: '测试2'},{price: 43, userUid: 0, item_name: '测试1'},{price: 66, userUid: 0, item_name: '测试2'},] [{price: 23, userUid: 0, item_name: '测试1'},{price: 55, userUid: 0, item_name: '测试3'},{price: 72, userUid: 0, item_name: '测试3'},{price: 82, userUid: 0, item_name: '测试3'},{price: 97, userUid: 0, item_name: '测试3'},] ] 麻烦各位大佬看看，感激不尽

const result: (typeof arr)[0][][] = new Array(items.length) .fill(0) .map(() => []) for (let flag = true, index = 0; flag; ) { flag = false items.forEach((v, i) => { const a = result[i] if (a.length < v.num) { a.push(arr[index++]) flag = true } }) } console.log(result) [ [ { price: 5, userUid: 0, item_name: "测试3" }, { price: 39, userUid: 0, item_name: "测试2" } ], [ { price: 20, userUid: 0, item_name: "测试2" }, { price: 43, userUid: 0, item_name: "测试1" }, { price: 66, userUid: 0, item_name: "测试2" } ], [ { price: 23, userUid: 0, item_name: "测试1" }, { price: 55, userUid: 0, item_name: "测试3" }, { price: 72, userUid: 0, item_name: "测试3" }, { price: 82, userUid: 0, item_name: "测试3" }, { price: 97, userUid: 0, item_name: "测试3" } ] ]
