Question

I’d like to add a click handler for a button using jQuery, but the handler needs to reference data supplied by the controller. Is there a way to access ViewData in a script block in ASP.NET MVC? Or do I need to construct the script in the controller?

If the script block is within the ASP.NET page then you can reference it…

e.g:

<script type='text/javascript'>     jQuery(document).ready(function() {         jQuery('#group-edit-form').validate({             rules: {                 title: {                     required: true,                     remote: '<%=Url.Action('ValidateGroupName', new { id = ViewData['GroupId'] }) %>?parentId=' + getParentId()                 }             },             messages: {                 title: {                     required: getMessage (7002),                     remote: '<%= ((MessagingModel)ViewData['Messages']).GetMessage (9001) %>'                 }             }         })      }); </script> 

When the page is processed by the runtime engine, everything within the <% … %> blocks is evaluated, regardless of it’s location in the page.
