addClass, removeClass, if hasClass issue
<p>I have 3 sets of buttons that behave like radio buttons. </p>

<p>The radio buttons work fine but I need to remove the active class for the button with an ID of #filter1-none ONLY if any of the other buttons have an active class. Would the best way be an if/then solution or can I do this with .filter?</p>

<p>This is the radio behavior.</p>

<pre><code>$('.filter .btn').click(function () {
    $(this).addClass('active').siblings('.active').removeClass('active');
});
</code></pre>

<p>This is the html:</p>

<pre><code>&lt;div class="btn-group pull-right filter" data-toggle="buttons-radio"&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-none"&gt;Show All&lt;/button&gt;
&lt;/div&gt;

&lt;div class="btn-group pull-right mr filter" data-toggle="buttons-radio"&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-LI"&gt;LI&lt;/button&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-LPO"&gt;LPO&lt;/button&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-NLI"&gt;NLI&lt;/button&gt;
&lt;/div&gt;

&lt;div class="btn-group pull-right mr filter" data-toggle="buttons-radio"&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-Low"&gt;Low&lt;/button&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-Medium"&gt;Medium&lt;/button&gt;
    &lt;button type="button" class="btn btn-large btn-flat" id="filter1-Urgent"&gt;Urgent&lt;/button&gt;
&lt;/div&gt;
</code></pre>
