// Disabling fields after 3 attempts.
if( attempt == 0) {document.getElementById("username").disabled = true ; document.getElementById("password").disabled = true; document.getElementById("submit").disabled = true; return false; } }

Answer 1

Check your html code, it works with:

<input type="text" id="username">
<input type="password" id="password">
<input type="submit" id="submit">

... maybe you haven't define ids but names ?
Else, test write to property 'disabled' outside conditional branch: this way you can view if problem is within the property assignement or related to the conditional enbranchment ;)
