Question

I want to run a fadeIn when a C# object is not null. I would imagine that the particulars shouldn’t matter, but just in case its asp.net MVC 3 – razor.

jQuery

---

<script type="text/javascript">
function MessageFadeIn(){
    $('messageLbl').fadeIn('slow', function () {
        //Animation complete
    });
}
</script>

ASP.NET

---

@if (ViewBag.Message != null)
{
   //run jquery to fade this label in below...the label shouldnt display unless jQuery runs
   <label id="messageLbl" style="background-color:Red;color:White;">@ViewBag.Message</label>
}

How can I accomplish this?

Answer 1

The messageLbl only exists if they message is not null so it will work.

jQuery does not throw an error if you try to fadeIn on a non existant object. It just fails gracefully.
