How to assign value for javascript variable from MVC asp.net controller

Question

Again stupid question struggling to assign a value for a javascript variable from controller ?

what is the proper way to assign value to a variable below line of code is failing .. Please advice

  var tenmp= '<%= Model.Temp%>';

Answer 1

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; %>

Answer 2

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.
