@deep_dhyaniOct 20.2005 — try this example

<html>

<head>

<Script Lanaguage="javascript">

frame_refresh_rate=1000;

mSecond=1500;

function get_update_data(){

window.hFrame.document.write(Math.random())

window.hFrame.location.reload(true);

}

function get_data_from_frame(){

ob=document.getElementById("tarea");

ob.innerHTML+=window.hFrame.document.body.innerHTML+"<br>";

}

window.setInterval("get_update_data()",frame_refresh_rate);

window.setInterval("get_data_from_frame()",mSecond);

</Script>

</head>

<body>

<div id='tarea'>12

</div>

<iframe id="hFrame" name="hFrame" style="display:none">

@tllcllauthorOct 21.2005 — I would like to know how to apply to the case where user enter/change the value of the 1st field, then this value is able to use in server side. from the example I'm not sure how to apply
