body: <p>How to change the error message for ASP.NET custom validator using javascript (client-side validation)?</p>
  
  <p>I know that we can easily change it using server side function i.e </p>
  
  <pre><code>customvalidtor1..ErrorMessage = "Error"
  </code></pre>
  
  <p>This will change error message for CustomValidator. How can we do same using client-side function? I have tried hard but did not find any answer.....</p>
