keyup event in js with example

Example 1: jquery keyup

// Similar to KeyUp but just called on input change (optimal for AJAX calls)
  var input = $('#formID').find('input[type="text"]');
  input.on('input',
    function(){
      console.log (input.val());
    });

Example 2: onkeyup

A function is triggered when the user releases a key in the input field
