Answer 1

var buttons = [];
//store radio buttons in the array buttons
//assign onKeyUp() to `onkeyup` attribute of the text input
function onKeyUp()
{
  var input = document.getElementById("txtInput_id");
  var text = input.value;
  if(text.length < 2)
    return;
  text = text.substring(text.length - 3);
  for(var i = 0; i < buttons.length; i++)
  {
    if(buttons[i].value == text)
      buttons[i].checked = true;
  }
}
