Hello I mam facing a problem with my script.
I am beginner in JS and I am trying to add event listener to buttons generated by a foreach but only the last button generated is responding to the addeventlistener.
I am also facing a pb of variable range with the getLocation(flight) function which is returning undefined outside the fuction while the console.log in the function is displaying the good variable value.
Can someone help?
