JavaScript to enable "submit" button (doesn't work)
<p>I need the button "submit" to be disabled unless JavaScript is on.</p>

<p>I tried:</p>

<p>1.</p>

<pre><code>&lt;input onLoad="this.disabled=false" id="post-comment" type="submit" 
value="Post Your Comment" disabled="disabled"/&gt;
</code></pre>

<p>2.</p>

<pre><code>&lt;input onLoad="this.removeAttribute('disabled');" id="post-comment" type="submit"
value="Post Your Comment" disabled="disabled"/&gt;
</code></pre>

<p>3.</p>

<pre><code>&lt;input onLoad="document.getElementById('post-comment').removeAttribute('disabled');"
id="post-comment" type="submit" value="Post Your Comment" disabled="disabled"/&gt;
</code></pre>

<p>Doesn't work. I'm new to JavaScript, but can't find answer on the net.</p>
