is this what you are looking for?

you can change the event name to change the behaviour.. for example.. if you change it to onchange, it will update testbox 2 when you leave textbox 1
<html>

<head>

</head>

<body>

  <input id="text1" type="text" onkeyup="document.getElementById('text2').value = this.value;"/>

  <input id="text2" type="text" />

</body>

</html>

you could add the code to a function, so you don't have to duplicate it
<html>

<head>

</head>

<body>

  <input id="text1" type="text" onkeyup="document.getElementById('text2').value = this.value;" onchange="document.getElementById('text2').value = this.value;"/>

  <input id="text2" type="text" />

</body>

</html>
