if(value != "")
{
document.getElementById('submitbutton').disabled = false;
}
else
{
document.getElementById('submitbutton').disabled = true;
}
{
document.getElementById('submitbutton').disabled = false;
}
else

misschien heb je er wat aan?

function DisableS(fieldid, buttonid)
{
if(document.getElementById(fieldid).value != null)
{
document.getElementById(buttonid).disabled=true;
}
else
{
document.getElementById(buttonid).disabled=false;
}
}
{
if(document.getElementById(fieldid).value != null)
{
document.getElementById(buttonid).disabled=true;
}
else
{
document.getElementById(buttonid).disabled=false;
}
}
Aan de functie aanroep geef je het id mee van het te controleren veld (de value hiervan mag niet leeg zijn) en het id van de submit button.

Dat maakt niet uit, heb ik al getest :)Naja, iig in Firefox werkt dat wel.. :)
De foutconsole in FF gaf aan dat NameForm/ NameField niet gevonden kon worden. Met de document.getElementById methode werkt het wel.
