title: Check only checkboxes with a specific value
body: <p>I am trying to check only checkboxes that have a specific value.
  I know how to get the value and I know how to check all checkboxes but I cannot figure out how to check only the ones with, lets say value of '200'</p>
  
  <p>My example code:</p>
  
  <pre><code>&lt;tr&gt;
      &lt;td&gt;&lt;input class="chk_box" type="checkbox" value="200" /&gt;&lt;/td&gt;
      &lt;td class="code"&gt;200&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input class="chk_box" type="checkbox" value="0" /&gt;&lt;/td&gt;
      &lt;td class="code"&gt;0&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input class="chk_box" type="checkbox" value="0" /&gt;&lt;/td&gt;
      &lt;td class="code"&gt;0&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input class="chk_box" type="checkbox" value="200" /&gt;&lt;/td&gt;
      &lt;td class="code"&gt;200&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;input class="chk_box" type="checkbox" value="300" /&gt;&lt;/td&gt;
      &lt;td class="code"&gt;300&lt;/td&gt;
  &lt;/tr&gt;
  
  &lt;input type="checkbox" class="checkbox_200" label="check 200"  /&gt;check 200
  </code></pre>
  
  <p>So now I need jQuery code to complete my code.
  I appreciate any help.</p>
  
  <p>BTW. Is there a way to check '200' and '300' in one go?</p>
  
  <p>UPDATED!</p>
