I want to copy data from one text box to another in html automatically i.e., as I edit the first text box the second one should reflect the same spontaneously.
call javascript function on onkeypresss
function copy_data(val){
var a = document.getElementById(val.id).value
document.getElementById(copy_to).value=a
}
EDITED USE onkeyup or onblur instead
<html>
<head>
<script>
function copy_data(val){
var a = document.getElementById(val.id).value
document.getElementById(copy_to).value=a
}
</script>
</head>
<body>
<input type=text name =a id=copy_from onkeyup=copy_data(this)/>
<input type=text name =a id=copy_to/>
</body>
</html>
