You can use the onchange event to track if the contents have been changed. It is also possible to compare current input[type=text].value to input[type=text].defaultValue. defaultValue will have the original value supplied in the value-attribute.

if you need to check this on separate event and can't use onchange event, you can compare objects defaultValue and value

Go about something like this:

var elem = document.getElementById('id here');

elem.onchange = function(){
  // your code here......
};
