how to select elements with more attributes?
<p>How can you select elements with more attributes?</p>

<pre><code>$('input[type="checkbox"]')
</code></pre>

<p>This will select all checkboxes, but how can you specify one more attribute in the selector?</p>

<pre><code>&lt;input type="checkbox" data-test="1" /&gt;
</code></pre>

<p>How can you select all checkboxes with the <code>data-test</code> attribute set too?</p>
