Currently in the process of creating a small script to tag coordinates in an array:
var countries = ['spain','australia'];
var leftX = ['270','575'];
var topY = ['60','220'];
When I need to retrieve them:
country = 'spain';
var left_ = leftX[countries.indexOf(country)];
var top_ = topY[countries.indexOf(country)];
This setup might be a bit confusing for my colleagues when updating. Any suggestions on how to simplify it?
var locations = {
"greece": {
leftX: '310',
topY: '85'
},
"japan": {
leftX: '495',
topY: '150'
}
}
//Next:
country = 'greece';
var left_ = locations[country].leftX;
var top_ = locations[country].topY;
I prefer organizing it in an object structure:
let countries = {
usa: { leftX: 200, topY: 80 },
// etc
}
This way, accessing the data becomes much simpler and there's no need to be concerned about support for .indexOf() (which may not work in older versions of IE):
country = 'usa';
var leftValue = countries[country].leftX;
var topValue = countries[country].topY;
In my approach, I prefer utilizing JavaScript objects for this particular task.
let countries = { mexico: {leftX: 150, topY: 100}, japan: { leftX: 400, topY: 300};
countries.mexico.leftX; // 150
// or
countries["mexico"].leftX; // 150
// or
countries['mexico']['leftX']; // 150
There are various ways to access the data in a traditional JavaScript way.
