Convert RFC 1123 date format to normal datetime in JavaScript

Question

I am using ASP.Net ajax calendar extender control to display date and time.

<asp:TextBox ID="tbxReceivedDate" CssClass="selectstyle" runat="server" MaxLength="100" Width="200" onblur="parseStringtoDateTime();"></asp:TextBox>
<cc1:CalendarExtender ID="CalendarExtender1" TargetControlID="tbxReceivedDate" Format="ddd MM/dd/yyyy hh:mm:ss tt" runat="server"></cc1:CalendarExtender>

This textbox returns datetime in this format "Tue 08/18/2015 4:44:40 PM" and I want to convert it to "08/18/2015 4:44:40 PM" in JavaScript.

Below code only selects date part, I also want the time part.

<script type="text/javascript">
    function parseStringtoDateTime() {
        var date = $find("behaviorID").get_selectedDate();
    }
</script>

How can I get this result?

It looks like you only want to remove first 4 characters.

Assuming you have a variable str="Tue 08/18/2015 4:44:40 PM" , then you just need var mydate = date.substring(3);
