Better way to fire save auto draft to database base on Textarea

Question

Can anyone give a better way to fire save_autodraft()? save_autodraft() function will save textarea value into my database base on Textarea input throught ajax.

onchange seems like a little bit not really efficient way and a little bit costly my server because user usually typing (make changes) every second and typing hundred or thousand characters on it. setTimeout?

Answer 1

Do both - throttle the function

var timeout;
element.on('input',function() {
   clearTimeout(timeout);
   timeout = setTimeout(function() {
       //save
   },1000);
});
