title: How can I customize the unobtrusive validation JQuery messages in ASP NET MVC?
body: <p>I have a form, and when it does the unobtrusive validtaion I want it to show:</p>
  
  <p>This message: <em>"Please enter a value.</em>"</p>
  
  <p>Instead of this message: <em>"This Field is required."</em></p>
  
  <p>I tried adding this at the end of my jquery.validate.unobtrusive.js file</p>
  
  <pre><code>(function ($) {
     $.extend($.validator.messages, {
       required: "Please enter a value."
     }); 
  }(jQuery));
  </code></pre>
  
  <p>But it's just not working.</p>
  
  <p>I also trying modifying directly the "messages" variable in jquery.validate.js file but it is not working either.</p>
  
  <p>Could you please tell me how can I get this done?</p>
