Question

Hi regarding https://github.com/shichuan/javascript-patterns/blob/master/general-patterns/function-declarations.html I define my JS function like this

<script language="javascript">
    var clearMessage = function ClearMessage() {
        $("#result").html("");
    };
</script>

And I try to call it in OnBegin method from MVC ajax,

@using (Ajax.BeginForm(new AjaxOptions() { HttpMethod = "post", OnBegin = "ClearMessage" }))

But I getting error that function not exit,
how to call my function that described by this best practice ? (without var clearMessage evering working correct)

Never seen such syntax. Don’t even know if it is valid javascript.

Try defining your function like this:

<script type="text/javascript">
    var ClearMessage = function() {
        $("#result").html("");
    };
</script>

or like this (which is pretty much the same):

<script type="text/javascript">
    function ClearMessage() {
        $("#result").html("");
    };
</script>
