title: one function for multiple buttons with different id
body: <p>I have</p>
  
  <pre><code>$('#BtOpenFile').click(function () { SetTimeextendBtn(); });
  </code></pre>
  
  <p>But There are multiple buttons with different IDs like <code>#BtAquire, #BtDelete, ...</code> and I want to use <code>SetTimeextendBtn()</code> for all of my buttons. I don't want to repeat the function.</p>
  
  <p>How can we do that?</p>
