映射键并创建一个新对象

Question

var str = "145.10880940000004,-37.9333893,10"
var view = str.split(",");
console.log(view);

Creates an array:

[
  "145.10880940000004",
  "-37.9333893",
  "10"
]

How do I dynamically map the keys so I have an object like this:

{
  Lng: "145.10880940000004",
  Lat: "-37.9333893",
  Zoom: "10"
}

Answer 1

This would work, using array destructuring:

 const input = "145.10880940000004,-37.9333893,10"; const [Lng, Lat, Zoom] = input.split(','); const output = {Lng, Lat, Zoom}; console.log(output); 

Answer 2

Similar to @Robby Cornelissen's answer, if you have multiple of these values, you can do this neatly with .map and parameter destructuring:

 const values = [ "145.10880940000004,-37.9333893,10", "145.10880940000004,-37.9333893,10", ]; console.log( values .map(str => str.split(',')) .map(([Lng, Lat, Zoom]) => ({Lng, Lat, Zoom})) );
