  </code></pre>
  
  <p>Using jquery I want to get that all tr having that color #4f4f4f.
  I did this code</p>
  
  <pre><code>$("#tbodyProjectList").find("tr[background-color:#404040]");
  </code></pre>
  
  <p>also did this too</p>
  
  <pre><code>$("#tbodyProjectList").find("tr background-color:#404040");
  </code></pre>
  
  <p>but not working. the object is empty. when I executed this in firebug it returns object[]</p>
