<form name=form1>
<input type=text name=t1 size=12 onkeydown="func()">
<input type=button name=b1 value=ok disabled>

高手指點.
來者有分
<script language=vbscript>
<!--
function func()
if form1.t1.value==""
form1.b1.disabled=true;
else
form1.b1.disabled=false;
end if
end function

<input type=text name=t1 size=12 onkeydown="func()">
<input type=button name=b1 value=ok disabled>
</form>
<script language=vbscript>
<!--

if ""=form1.t1.value then
form1.b1.disabled=true
