如何将对象数组转换为特定格式的对象？
我一直在努力解决一个问题，我试图以更好的方式解决这个问题。基本上我有一个集合，或者更简单地说是一个对象数组。我将把集合粘贴下来：

这是一个相当紧凑的示例，使用嵌套reduce()调用并将描述层次结构的键数组传递给内部reduce()。这允许您通过传递不同的层次结构数组以多种方式重构原始数组。const srcArr = [{ "pluginId": "fy9h-dKw", "pluginVersion": 1, "pcVersion": "4.26", "platform": "win", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw", "pluginVersion": 1, "pcVersion": "4.26", "platform": "mac", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw", "pluginVersion": 1, "pcVersion": "4.26", "platform": "linux", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw1", "pluginVersion": 1, "pcVersion": "4.26", "platform": "win", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw1", "pluginVersion": 1, "pcVersion": "4.26", "platform": "mac", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw1", "pluginVersion": 1, "pcVersion": "4.26", "platform": "linux", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw2", "pluginVersion": 1, "pcVersion": "4.26", "platform": "win", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }]function refactorArray(arr, tree) { return arr.reduce((a, o) => { const inner = tree.reduce((ka, k) => { const match = ka.find(e => e.name === o[k]); if (match) { ka = match.children; } else { const n = { name: o[k], children: [] }; ka.push(n); ka = n.children; } return ka; }, a); inner.push({ ...o }); return a; }, []);}const tree1 = [ 'pluginId', 'pcVersion', 'pluginVersion', 'platform'];console.log(refactorArray(srcArr, tree1)); const tree2 = [ 'platform', 'pluginVersion'];console.log(refactorArray(srcArr, tree2));或者用来bind()创建专用函数......const srcArr = [{ "pluginId": "fy9h-dKw", "pluginVersion": 1, "pcVersion": "4.26", "platform": "win", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw", "pluginVersion": 1, "pcVersion": "4.26", "platform": "mac", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw", "pluginVersion": 1, "pcVersion": "4.26", "platform": "linux", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw1", "pluginVersion": 1, "pcVersion": "4.26", "platform": "win", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw1", "pluginVersion": 1, "pcVersion": "4.26", "platform": "mac", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw1", "pluginVersion": 1, "pcVersion": "4.26", "platform": "linux", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }, { "pluginId": "fy9h-dKw2", "pluginVersion": 1, "pcVersion": "4.26", "platform": "win", "previews": [{ "uri": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.jpg" }], "pluginUrl": "/e2d4-dKv/4.26/1/7f4bc5e9-3721-4f83-abd4-75792ae75e3d.zip" }]function refactorArrayByBoundTree(arr) { return arr.reduce((a, o) => { const inner = this.reduce((ka, k) => { const match = ka.find(e => e.name === o[k]); if (match) { ka = match.children; } else { const n = { name: o[k], children: [] }; ka.push(n); ka = n.children; } return ka; }, a); inner.push({ ...o }); return a; }, []);}const tree1 = [ 'pluginId', 'pcVersion', 'pluginVersion', 'platform'];const refactorByTree1 = refactorArrayByBoundTree.bind(tree1);console.log(refactorByTree1(srcArr)); const tree2 = [ 'platform', 'pluginVersion'];const refactorByTree2 = refactorArrayByBoundTree.bind(tree2);console.log(refactorByTree2(srcArr));
