    copied!<p>Quick question on the <code>.data()</code> in jQuery: My variable "valone" reaches into a dropdown menu within some HTML for the "data-whatever" value in the dropdown and then plugs it into the jQuery equation. But it also seems to be getting the "option value" value from the dropdown and includes it into the math somehow, even though I don't specify it to do so...</p> <pre><code>var valone = $('#os0 option:selected').data('whatever'); </code></pre> <p>Am I missing something in this <code>.data()</code> function? Or do I have something extra that is not necessary? (I have the complete jQuery and HTML below.)</p> <p><strong>jQuery</strong></p> <pre><code>$(document).ready(function(){ var valone = $('#os0 option:selected').data('whatever'); var valtwo = $('#os1').val(); var valthree = $('#os2').val(); var total = ((valone * 1) * (valtwo * 1) * (valthree * 1)); $('.calc').each(function(){ if($(this).val() != '') { total += parseInt($(this).val()); } }); </code></pre> <p><strong>HTML</strong></p> <pre><code>&lt;select style="width: 190px;" class="calc" name="os0" id="os0" type="text"&gt; &lt;option value="250" data-whatever="5"&gt;250 &lt;/option&gt; &lt;option value="500" data-whatever="6"&gt;500 &lt;/option&gt; &lt;option value="1000" data-whatever="7"&gt;1000 &lt;/option&gt; &lt;option value="2000" data-whatever="8"&gt;2000 &lt;/option&gt; &lt;option value="5000" data-whatever="9"&gt;5000 &lt;/option&gt; &lt;/select&gt; </code></pre> <p>Any help or advice would be greatly appreciated! </p>
