I see I can use the @ sign to do things like Url.Action(). But how do I reference the properties for the Model that the page is strongy typed to?


Thanks.

From the introduction:

"While JavaScript blocks declared inline on the view page can easily consume values from the model..."

My JavaScript is declared in the MVC3 Razor file thusly:

@section Scripts
{
   @Html.Partial("Parts.Index.Scripts")
}

Does this change anything? I do not relish needing to dig into this JSon project described in the URL you'd attached. Is there an easier way?

For example, is there a built in Html Helper that can return the Model inside the JavaScript?

Something similar to...

function myFunc() {
   var myVal = @Html.SomeHelper(model => model.MyValue);

    or

  var myVal = @HtmlHelper.SomeHelper(model => model.MyValue);

}

Thanks.

From my above link:

Place scripts in partial views

Instead of following best-practices and placing JavaScript in an external script file, scripts can instead be placed in partial views.  This simplifies the main view by encapsulating the script, and it does allow the script to be re-used.  It also allows the script to easily reference values from the view model.

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<AwesomeViewModel>" %>
<script type="text/javascript">
 
alert('Hello from the view model: <%=Model.Hello%>');
 
</script>
