modify checkbox using javascript
<p>I had declared 5 checkboxes with name and id attribute in a html:</p>

<pre><code>&lt;input type="checkbox" name="category" value="One" id=11&gt;One&lt;br/&gt; 
&lt;input type="checkbox" name="category" value="Two" id=12&gt;Two&lt;br/&gt; 
&lt;input type="checkbox" name="category" value="Three" id=13&gt;Three&lt;br/&gt; 
&lt;input type="checkbox" name="category" value="Four" id=14&gt;Four&lt;br/&gt;
</code></pre>

<p>After declaration, I want to run a javascript that would enable the checkbox1 using that checkbox id.</p>

<p>Let me know to clarify something.</p>
