数组在对象内部拆分

Question

I have an object Regions{} which stores multiple objects, following code block showing countryName : [regions,..,..]

Regions = { Afghanistan:["Badakhshan~BDS", "Badghis~BDG", "Baghlan~BGL"]
            Albania:["Berat~01", "Dibër~09", "Durrës~02",]
          }

Which giving me result like this:

Afghanistan: Array(n)
0: "Badakhshan~BDS"
1: "Badghis~BDG"

what I am trying to achive is :

Afghanistan: Array(n)    
0:{value: "Badakhshan", lable: "BDS"}
1:{value: "Badghis", lable: "BDG"}

thanks in advance

PS: for the sake of some ruthless fellows following is the code what I have tried yet

   let countries = CountryRegionData
      let regions = {}
      countries = countries.map(country => {
        regions = {
          ...regions,
          [country[0]]: country[2].split('|')
        }
        return {
          value: country[1],
          label: country[0]
        }
      })

      console.log("countries",countries)
      console.log("regions",regions)

     let values = regions["Afghanistan"]; 
     values = values.map(value =>{
       return {
         value: value,
         lable: value
       }
     })

Answer 1

You can use split and map , this code is changing values in original object, if you want to build a new object you can use reduce instead of forEach

 let Regions = { Afghanistan: ["Badakhshan~BDS", "Badghis~BDG", "Baghlan~BGL"], Albania: ["Berat~01", "Dibër~09", "Durrës~02", ] } Object.entries(Regions).forEach(([key,value])=>{ Regions[key] = value.map(data=>{ let [value,label] = data.split('~') return {value,label} }) }) console.log(Regions) 

Answer 2

Do something like:

Regions.map(region => region.map(txt => {
  const [val, lbl] = txt.split("~");
  return { value: val, lable: lbl};
}));

Answer 3

Messy but gets the work done. Using nested forEach loops

 var Regions = { Afghanistan: ["Badakhshan~BDS", "Badghis~BDG", "Baghlan~BGL"], Albania: ["Berat~01", "Dibër~09", "Durrës~02", ] } var ar = []; Object.keys(Regions).forEach(function(e) { Regions[e].forEach(function(k) { var arr = k.split('~'); ar.push({ value: arr[0], label: arr[1] }) }) Regions[e] = ar; ar = []; }) console.log(Regions) 

Answer 4

Use the map function to iterate the object.

 Regions = { Afghanistan: ["Badakhshan~BDS", "Badghis~BDG", "Baghlan~BGL"], Albania: ["Berat~01", "Dibër~09", "Durrës~02", ] }; const finalObject = Object.keys(Regions).map(region => { return { [region]: Regions[region].map(country => { const [value, lable] = country.split("~"); return { value, lable }; }) }; }); console.log(finalObject);
