Simplifiying variables in jQuery
<p>How do I simplify the following code?</p>

<p>It is just a static ID.</p>

<pre><code>&lt;script&gt;
    $x('input[id="id1"]').attr('checked', true);
    $x('input[id="idx4"]').attr('checked', true);
    $x('input[id="idk5"]').attr('checked', true);
&lt;/script&gt;
</code></pre>
