对JavaScript中除一个元素以外的数组进行排序 [英] Sort an array except one element in JavaScript

问题描述

我有一个数组，正在对其进行排序，但是我需要对除数组中一个元素之外的所有内容进行排序.

I have an array and I am sorting it but I need to sort everything except one element of my array.

我的数组是:

var Comparison = [
    {key: "None", value: "None"},
    {key:"Geographical Area", value:"Geographical_Area"},
    {key:"Forests", value:"Forests"},
    {key:"Barren Unculturable Land", value:"Barren_Unculturable_Land"},
    {key:"Land put to Non agricultural use", value:"Land_put_to_Non_agricultural_use"},
    {key:"Land Area", value:"Land_Area"},
    {key:"Water Area", value:"Water_Area"},
    {key:"Culturable Waste", value:"Culturable_Waste"},
    {key:"Permanent Pastures", value:"Permanent_Pastures"},
    {key:"Land under Tree Crops", value:"Land_under_Tree_Crops"},
    {key:"Fallow Land excl Current Fallow", value:"Fallow_Land_excl_Current_Fallow"},
    {key:"Current Fallow", value:"Current_Fallow"},
    {key:"Total Unculturable Land", value:"Total_Unculturable_Land"},
    {key:"Net Sown Area", value:"Net_Sown_Area"},
    {key:"Gross Sown Area", value:"Gross_Sown_Area"},
    {key:"Cropping Intensity", value:"Cropping_Intensity"} ];

我正在使用以下代码对该数组进行排序:

I am sorting this array using this code:

var Comparison_sort = this.Comparison.sort(function (a, b) {
  if (a.key < b.key)
      return -1;
  if (a.key > b.key)
      return 1;
  return 0;
});

这对我的数组进行了完美排序，但是我希望其中一个元素位于顶部，这意味着我的元素None应该位于顶部，并对所有其他元素进行排序.

This is sorting my array perfectly, but I want one of my elements to be on top, meaning my element None should be on top and sort all other elements.

例如，我得到以下结果:

For example, I am getting this result:

   {key: "Barren Unculturable Land", value: "Barren_Unculturable_Land"}
   {key: "Cropping Intensity", value: "Cropping_Intensity"}
   {key: "Culturable Waste", value: "Culturable_Waste"}
    ....
   {key: "None", value: "None"}

但是我想要这样的结果:

But I want a result like this:

   {key: "None", value: "None"}
   {key: "Barren Unculturable Land", value: "Barren_Unculturable_Land"}
   {key: "Cropping Intensity", value: "Cropping_Intensity"}
   {key: "Culturable Waste", value: "Culturable_Waste"}
    ....

我看到了一个答案， 在TypeScript中排序数组 ，但我无法使用此答案解决我的问题.

I saw an answer, Sort array in TypeScript, but I was unable to use this answer to my problem.

推荐答案

var Comparison_sort = this.Comparison.sort(function (a, b) {
  if(a.key == b.key) return 0;
  if (a.key == 'None') return -1;
  if (b.key == 'None') return 1;

  if (a.key < b.key)
      return -1;
  if (a.key > b.key)
      return 1;
  return 0;
});

告诉定期进行排序，除非密钥为空，这意味着它必须先行."

tells "do a regular sort, except if the key is none which means it must go first."
