title: How to get unselected value in dropdown jquery
body: <p>I am using following html for dropdown</p>
  
  <pre><code>&lt;select class="form-control" id="iddeStatus" name="iddeStatus"&gt;
                                   &lt;option value=""&gt;--Select ID De-dup Status--&lt;/option&gt;
                                   &lt;option value="PASSED"&gt;Passed&lt;/option&gt;
                                   &lt;option value="FAILED"&gt;Failed&lt;/option&gt;
                                &lt;/select&gt;
  </code></pre>
  
  <p>And below is my jquery code to get dropdown value</p>
  
  <pre><code>var iddeStatus = $("#iddeStatus").val();
   if((iddeStatus!=null)||(iddeStatus!="")){
  ...
  }else{
  ...
  }
  </code></pre>
  
  <p>Problem is, even if i dont select the value, control goes inside the if statement.</p>
