6,931 PointsUsing functions for both widgets
I'm trying to reuse code for both (rooms and employees) widgets with one universal function. I've managed to pass parameters for each list but the problem I'have faced - I can't get parsed JSON from function with return
.
Here is the code without parameters
function getData2() {
let rhr = new XMLHttpRequest();
rhr.onreadystatechange = function () {
if (rhr.readyState === 4) {
rooms = JSON.parse(rhr.responseText);
}
}
rhr.open('GET', 'data/rooms.json');
rhr.send();
return rooms;
}
let x = getData2();
console.log(x); // undefined
What is the correct solution?
