I've just tried the same as you and it works fine.

<script language="javascript">
    var a = '<%=Model.userName %>';

    alert(a);
</script>

In my controller I have the following;

public ActionResult Login()
{
    LoginFormViewModel loginFVM = new LoginFormViewModel();
    loginFVM.userName = "slappy";

    return View(loginFVM);
}

All the above assumes that you are trying to get a model value into javascript from your view.

Also, ensure that your view is inheriting from your model else it'd have no idea what temp is.

Hope this is of help.

You don't need to write, use <% in controllers.

You would probably be using it in aspx/ ascx pages, something like

<input type="hidden" class="pnum" value="<%=PageNum%>" />

if you are using in aspx or ascx page then directly use

<% var tenmp= Model.Temp; %>
