jQuery to Javascript code converting
<p>I have not a good Javascript knowledge, but I'm kinda good with jQuery though. I want to change some jQuery code to pure Javascript, but I have no idea how to do it.</p>

<pre><code>$(document).ready(function() 
{
    $('#block').one('click', function()
    {
       $(this).val('{L_SEND_CONFIRM}').removeClass('button1');
       $('#replacement').val('{L_BLOCK_CODE}');
    });
});
</code></pre>

<p>Anyone willing to help me out please? </p>

<p>P.S: Sorry for asking such a dumb question, I really need to learn Javascript myself ASAP.</p>
