Question

I need to check if user is typing or not before i send an ajax request so my server is not hammered with every stroke, can someone guide me on how to do this?

Answer 1

What you are looking for is debouncing/throttling. Underscore.js has useful functions for it.

$('#field').on('keyup change', _.debounce(function() {
    // your ajax call
}), 2000);

This code would wait 2s after the last change before running your function.
