基于另一个数组的值的打字稿顺序数组

泰伦斯·杰克逊

可以说我有一个基本数组

let object2 = ["DotNet", "ETL", "Hadoop", "Java", "Oracle", "Pega", "MainFrame"]

我想按基本数组的相同顺序对第二个数组进行排序

 let object1 = [{Name: "Java", ResourceCount: 3}, {Name: "DotNet", ResourceCount: 4}, {Name: "Hadoop", ResourceCount: 1}, {Name: "Pega", ResourceCount: 2}, {Name: "Oracle", ResourceCount: 1}, {Name: "ETL", ResourceCount: 1}, {Name: "MainFrame", ResourceCount: 0}]

所以看起来像这样

object1 = 
[{Name: "DotNet", ResourceCount: 4},
{Name: "ETL", ResourceCount: 1},
{Name: "Hadoop", ResourceCount: 1},
{Name: "Java", ResourceCount: 3}, 
{Name: "Oracle", ResourceCount: 1},
{Name: "Pega", ResourceCount: 2},
{Name: "MainFrame", ResourceCount: 0}]

没有硬编码怎么办？

一种可能的解决方案是使用Array.map来迭代您的已排序名称列表-并将每个名称“映射”String到对象列表中的相关对象中。

使用进行关联Array.find，该接收返回相关对象的函数作为参数：

const list1 = ["DotNet", "ETL", "Hadoop", "Java", "Oracle", "Pega", "MainFrame"];
const list2 = [{Name: "Java", ResourceCount: 3}, {Name: "DotNet", ResourceCount: 4}, {Name: "Hadoop", ResourceCount: 1}, {Name: "Pega", ResourceCount: 2}, {Name: "Oracle", ResourceCount: 1}, {Name: "ETL", ResourceCount: 1}, {Name: "MainFrame", ResourceCount: 0}];

const ordered = list1.map(function(nameValue) {
  return list2.find((obj) => (obj.Name === nameValue));
});

console.log(ordered);
