I'm trying to write the following code inside ASP.Net-MVC razor view but the page won't compile.

<script>     



    @(if (Model.IsValid))

     {

        (#ErrorMessage).text(Error);

     }

    else

    {

       (#Registration).text(Done!);

    }



</script>

There are workarounds that I did to achieve that operation, but is there a simple way?

Try like this:

<script type=text/javascript>

    @if (ViewData.ModelState.IsValid)

    {

        <text>$('#ErrorMessage').text('Error');</text>

    }

    else

    {

        <text>$('#Registration').text('Done!');</text>

    }

</script>

Things to notice:

usage of ViewData.ModelState.IsValid to test if there are modelstate errors

usage of the special <text> to indicate to the razor parser to use the text as is

usage of the $ function as I suppose this is jQuery code

properly closing quotes around javascript strings

usage of the type=text/javascript attribute on the script tag.
