Question

Using the jQuery Validation plugin and AJAX, how can I validate the contents of say an input (textbox) but pass more than one parameter to a controller action?

A brilliant example of passing a single value via AJAX using the plugin can be found here.

Looking at the code for jQuery Validation it looks like the post data can not be customized. So you’ll have to stick with query parameters:

 <script type='text/javascript'> $(document).ready(function(){   $('#form-sign-up').validate(   {     var param1 = $('#mytextbox').val();      rules:     {         login:         {           required: true,           remote: '<%=Url.Action('IsLoginAvailable', 'Accounts') %>?param1=' + param1         }       }       });  }); </script>
