按 1 个或多个属性值对对象数组进行排序

Question

我正在弄清楚是否有更好的方法来对下面的数组进行排序。

下面的代码根据 label 和 deviceRegistered 对数组进行排序。 如果 label 是桌面电话并且 deviceRegistered 为真，那么它应该优先。

我的方法如下。

const terminals = [
  {
    "device":"JKJCF00",
    "directory":"+1899990000",
    "label":"Jabber",
    "deviceRegistered":"false"
  },
  {
    "device":"IOP8999",
    "directory":"9099886644",
    "label":"Desk Phone",
    "deviceRegistered":"false"
  }, 
  {
    "device":"KLJ7888",
    "directory":"+8999999",
    "label":"Jabber",
    "deviceRegistered":"true"
  },  
  {
    "device":"VFD87987",
    "directory":"+12386444",
    "label":"Desk Phone",
    "deviceRegistered":"true"
  }]

let term = [...terminals],arr=[],sortedLines = [],lineObj ={};
  term.forEach(line => arr.indexOf(line.label)===-1 ? arr.push(line.label):'');
  arr.forEach(device => {
     let filterArr = term.filter(line => line.label === device)
     let sortArr = [...filterArr].sort((dev1,dev2) => dev1.deviceRegistered !== 'true' ? 1 : dev2.deviceRegistered !== 'true' ? -1 : 0)
     lineObj[device] = sortArr
  })
  for (line in lineObj){ console.log(lineObj[line])
     sortedLines.push(...lineObj[line])
  }
}

output 是

[
  {
    "device":"KLJ7888",
    "directory":"+8999999",
    "label":"Jabber",
    "deviceRegistered":"true"
  },
  {
    "device":"JKJCF00",
    "directory":"+1899990000",
    "label":"Jabber",
    "deviceRegistered":"false"
  },
  {
    "device":"VFD87987",
    "directory":"+12386444",
    "label":"Desk Phone",
    "deviceRegistered":"true"
  },
  {
    "device":"IOP8999",
    "directory":"9099886644",
    "label":"Desk Phone",
    "deviceRegistered":"false"
  }
]

Answer 1

您可以检查属性并使用 boolean 值的增量。

 const array = [ { device: "JKJCF00", directory: "+1899990000", label: "Jabber", deviceRegistered: "false" }, { device: "IOP8999", directory: "9099886644", label: "Desk Phone", deviceRegistered: "false" }, { device: "KLJ7888", directory: "+8999999", label: "Jabber", deviceRegistered: "true" }, { device: "VFD87987", directory: "+12386444", label: "Desk Phone", deviceRegistered: "true" } ]; array.sort((a, b) => (b.label === 'Desk Phone') - (a.label === 'Desk Phone') || (b.deviceRegistered === 'true') - (a.deviceRegistered === 'true') ); console.log(array);

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

假设：我是这个库的作者，但我创建了 sort-es 正是为了简化数组排序。

如果您有兴趣：文档GH

import { byValues, byString, byValue, byBoolean } from "sort-es"

const terminals = [] //...items

const sorted = terminals.sort(byValues([
    ["label", byString()],
    ["deviceRegistered", byValue(d => d === 'true', byBoolean())]
]))
