MOUSEOVER: How to start a function and let it play until the end without start it over and over?

Question

I want to start a function when I over mouse an ID #show-details. But I need it to start only one until it ends, not to start over and over again ...

With my code below It starts when I mouseover it but starts over and over even if it doesn't finish. I need some help :)

function showDetails() {

  var details = document.getElementById('show-details');

  details.addEventListener('mouseover', initDetailsLetters);

}

i think you need a flag, if the flag doesnt exist then create it and start over, if it does exist then dont run the code

Try a callback function, I have found this example to help you: Proper way to wait for one function to finish before continuing?

This looks similar to your problem
