Use disabled attribute to disable the submit button initially.
eg.[html]<input id="button" type="submit" disabled>[/html]
To enable it, use object.disabled =true | false (example)
on the onkeyup event of textbox (text input)
[html]<input type="text" name="abc" onkeyup="docume nt.getElementBy Id('button').di sabled = this.value=='' ? true : false;">[/html]
