I have a website where there is a empty box and a input text box. I want to be able to type something in that input box and have it be printed on the empty box.

Angular JS does this in two lines of code :

Just import Angular JS as you import other libraries :
```
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js">
```
Then, on you first div (where you are copying from):
```
<input type="text" ng-model="myID"> </input>
```
Then, on the place where you will show the content : just write :
```
<div> {{myID}}</div>
```
This is the best solution I have ever found !

You use the onkeyup event

Searching with ids is a lot easier. Add ids to your elements as follows:

<div class='printchatbox' id='printchatbox'></div>

<input type='text' name='fname' class='chatinput' id='chatinput'>

var inputBox = document.getElementById('chatinput');

inputBox.onkeyup = function(){
    document.getElementById('printchatbox').innerHTML = inputBox.value;
}

In your HTML,

<div id='printchatbox'></div>
<br>
<input type='text' id='fname' class='chatinput' onkeyup="annotate()">

In JS,

function annotate(){
  var typed= document.getElementById("fname").value;
  document.getElementById("printchatbox").innerHTML= typed;
}

There are many ways to get this done, possibly the easiest is to use jQuery. In the example below I am using the jQuery keyUp() function to listen for keyboard events, then writing the updated value to the .printChatBox

<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.0.min.js"></script>
</head>
<body>

  <div class='printchatbox'>CHANGE ME</div>
  <input type='text' name='fname' class='chatinput'>

<script type="script/javascript">
  $('.chatinput').keyup(function(event) {
    newText = event.target.value;
    $('.printchatbox').text(newText);
  });
</script>
</body>
</html>

I've posted a working example here: http://jsbin.com/axibuw/1/edit
