JQuery Dialog - NOT OPENING Second Time

Question

There are several posts on StackOverflow on the subject but none of the answers helped me. I am using the DataList control that is populated by a SELECT through a DataAdapter. A concept is recommended that only one instance of the dialog must be open but could not apply this method

The structure of the html is:

<asp:DataList ID="DataList" runat="server">
         <ItemStyle />
         <ItemTemplate>
             <a href="" class="link"/></a>
             <div class = "dialog" id="dynamicID" style="display:none">
             </ div>
         </ ItemTemplate>
     </ asp: DataList>

The jQuery code I'm using is:

<script language="javascript" type="text/javascript">
     $ (function () {
         $ (". link. ") click (function () {
             var id = '#' + ($ (this). siblings ('. dialog'). attr ('id'));
             $ (id). dialog ({
                 AutoOpen: false,
                 closeOnEscape: true,
                 resizable: false,
                 draggable: false,
                 modal: true,
                 width: 800,
                 height: 600,
                 overlay: {backgroundColor: "# 000", opacity: 0.5},
                 top: 20,
                 show: 'fade',
                 hide: 'fade',
                 buttons: {
                     "Close": function () {
                         $ (id). dialog ('close');
                     }
                 }
             });
             $ (id). dialog ('open');
         });
     });
</ script>

Imagine this HTML

<asp:DataList ID="dataList" runat="server">
    <ItemTemplate>
        <div class="row">
            <p>
                Result: <strong>
                    <%# Container.DataItem.ToString() %></strong></p>
            <a href="#" class="link" data-open="dialog_<%# Container.ItemIndex %>" />Click
            To Open</a>
            <div class="dialog" id="dialog_<%# Container.ItemIndex %>">
                <h2>
                    This is the text inside the dialog #
                    <%# Container.ItemIndex %>.</h2>
                <p>
                    &nbsp;
                </p>
            </div>
        </div>
    </ItemTemplate>
</asp:DataList>

with this javascript

$(function () {

    // create dialogs
    $(".dialog").dialog({
        autoOpen: false,
        closeOnEscape: true,
        buttons: {
            "Close": function () {
                $(id).dialog('close');
            }
        }
    });

    // hook up the click event
    $(".link").bind("click", function () {
        // console.log($(this).parent());
        // open the dialog
        var dialogId = $(this).attr("data-open");
        $("#" + dialogId).dialog("open");

        return false;
    });

});

works lovely.

What is wrong with your approach?

you are creating the dialog's inside a method, and this should be created inside the $(document).ready() so, everytime you click, it creates a dialog, but... it already exists and screws up everything.

When working with dialogs:

• First you create them using .dialog()
• You just need to use .dialog('open') to make that dialog visible
• And use .dialog('close') to hide that dialog

by default jQuery UI CSS will hive the dialogs automatically (display:none;) so you don't need to do anything like that.
