See if you can work with the following



<SCRIPT>
<!--
function chk(){
if (document.form1.t1.value=='')
document.form1.button.disabled=true
else{
document.form1.button.disabled=false
}
if (document.all)
setTimeout("chk()",100)}
setTimeout("chk()",500)
// -->
</SCRIPT>

<FORM name=form1><P><INPUT type=text name=t1>
<INPUT type=submit value=Submit name=button>
<INPUT type=reset value=Reset>
</FORM>

You did say 'link' - right?

<html>
<head>
<title>untitled</title>
<script type="text/javascript" language="javascript">

function link_enable(link) {
if (typeof link.disabled != 'undefined') link.disabled = false;
link.onclick = null;
}

</script>
</head>
<body>
<form>
<input name="t1" type="text" onchange="link_enable(document.links[0])" />
<a href="http://www.codingforums.com" onclick="return false" disabled="disabled">LINK</a>
</body>
</html>

link_enable(document.links[1])
This is an array containing references to all link objects in the document. The index starts at 0.
