i found this just try this code

<html>
<head>
<script type="text/javascript">
function toggle(e, show) { e.style.visibility = show ? 'visible' : 'hidden' }
onload = function() { toggle(document.getElementById('info'), false) }
</script>
</head>
<body>
<script type="text/javascript">
document.write('<div><label for="toggle"><input type="checkbox" onclick="toggle(document.getElementById(\\'info\\'), this.checked)" id="toggle">Show/Hide</label></div>');
</script>
<div id="info" style="visibility: visible">This is some extra information.</div>
</body>
</html>

I just use the onclick and it works, thank you.

<TD Align='left' height='64%'> <input type='checkbox' name ='Classification' value='SGA_network_ID' onclick= "WhenChecked()"> SGA network ID </ TD>

and function Onchecked ()
Code:

WhenChecked function ()
(
if (document. form. Classification [2]. checked == 1)
(
document. form. Sganet_textbox. disabled = false;
)
else
(
document. form. Sganet_textbox. disabled = true;
)
)
it works without the timeout ...
