Hey there, I've got a JSON return object that looks like this:
color_selected = [
{ id: 4},
{ id: 3}
];
Any tips on how I can convert it to the following format?
color_selected = [4,3]
Appreciate any help or suggestions you may have. Thanks!
To loop through the array, you can follow this method:
let colorsArray = [];
for(let index = 0; index < selected_colors.length; index++) {
colorsArray.push(selected_colors[index].id);
}
To achieve this, utilize the JavaScript map function.
var newSelection = colors.map(item => item.code)
var colors = [
{ code: "#FF0000" },
{ code: "#00FF00" }
];
var newSelection = colors.map(item => item.code)
console.log(newSelection)selected_colors = [
{ id: 4},
{ id: 3}
];
You have the option to leverage lodash library
// available in version 3.10.1
_.pluck(selected_colors, 'id'); // → [4, 3]
_.map(selected_colors, 'id'); // → [4, 3]
// included in version 4.0.0
_.map(selected_colors, 'id'); // → [4, 3]
Implement the use of Array.map() along with the ES6 Arrow operator for JavaScript.
var color_selected = [
{ id: 4},
{ id: 3}
];
color_selected = color_selected.map(item => {return item.id });
