  <pre><code>&lt;input type="text" name="keyword" onkeyup="searchFunction()" style="width:300px;" /&gt;
  </code></pre>
  
  <p>Javscript</p>
  
  <pre><code>    function searchFunction() {
      $(".contact-name") /*Contact-name is the name of the div*/
      .hide()
      .filter(":contains('" + $("input[name='keyword']").val() + "')")
