How to check by jQuery the value some checked checkboxes attribute value?
<p>I need some help, I have some checkboxes like that</p>

<pre><code>&lt;input class="some-class" type="checkbox" has-format="0"&gt;
</code></pre>

<p>or</p>

<pre><code>&lt;input class="some-class" type="checkbox" has-format="1"&gt;
</code></pre>

<p>Is it possible, to check, if all of that checked checkboxes has the <code>has-format</code> value = 1 or 0 ? I mean, e.g. if I want to check = 1 then if any of the checked checkboxes has that value 0 then I'll get false</p>
