Hi, I have these codes and it's works well. But the problem is the button disabled ONLY when the input is filled. I would like that the button should be disabled on loading page if the a word is inside of input. Then if nothing is inside on loading page should still disabled. Thank you!
<script>
function manage(txt)
{
var bt = document.getElementById('btSubmit');
if (txt.value != '')
{
bt.disabled = false;
}
else
{
bt.disabled = true;
}
}
</script>
