I have a user control, shown below.  However, due to the javascript, I can have only once instance on a page.   I do not know how to make it reusable, due to the javascript.   I need help.  Thank You.


<%@ Control Language="VB" AutoEventWireup="false" CodeFile="TaborCalendarPopup.ascx.vb" Inherits="Shared_TaborCalendarPopup" %>


<script language="JavaScript" type="text/javascript" src = '../scripts/CalendarPopup.js'> </script>

<script language="JavaScript" type="text/javascript">    var cal1 = new CalendarPopup('divCalendarPopup'); </script>

<div id="divCalendarPopup" style="position:absolute; visibility:hidden; background-color:white;"></div>

<asp:TextBox ID="txtDate" runat="server" clientidmode="static"
                     onkeydown="AllowDate(event);" 
                    width="100px" MaxLength="10"></asp:TextBox>

<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="../Images/DateSelector.gif" 
                onclientclick="cal1.select(document.forms[0].txtDate,'txtDate','MM/dd/yyyy'); return false;"/>

<script language="JavaScript" type="text/javascript">

    function AllowDate(evt) {

        var BACKSPACE = 8;
        var FORWARD_SLASH = 191;
        var DELETE = 46;
        var ENDKEY = 35;
        var DOWN_ARROW = 40;
        var ZERO = 48;
        var NINE = 57;
        var NUMPAD0 = 96;
        var NUMPAD9 = 105;
               

        var keyCode = (evt.keyCode ? evt.keyCode : evt.which);

        if (evt.shiftKey) {
            evt.preventDefault();
        }

        else if (!((keyCode == BACKSPACE) ||
                    (keyCode == FORWARD_SLASH) ||
                    (keyCode == DELETE) ||
                    (keyCode >= ENDKEY && keyCode <= DOWN_ARROW) ||
                    (keyCode >= ZERO && keyCode <= NINE) ||
                    (keyCode >= NUMPAD0 && keyCode <= NUMPAD9))) {
            evt.preventDefault();
        }

    }

</script>

Are you talking about AllowDate Function? Create a separate js file and  include it
<script language="JavaScript" type="text/javascript" src = 'filelocation.extension[js]'> </script>

Open in new window

You can call function as you required.

Sorry, no not the allow date.  I'm not positive what the issue is, but I mean the fact that I'm using clientidmode="static" on the textbox.  it has to be static because of the onclientclick of the image button; without static it does not work.   However, if I put two of these controls on my page, neither works; It get an error in the CalendarPopup.js code.  I was assuming because ya can't have two elements with an ID of  txtDate.

You will need to replace that static name with a find of some sort. You can use JQuery or plain javascript to traverse the DOM and get the txtDate relative to the current instance of control.

thanks.  that gave me an idea.  I assigned a unique class runtime for each instance , then find the class in javascript using document.getElementsByClassName(className)
