Question

I have 2 Razor views where one is loading the other in a jQuery UI dialog. In the view that get loaded in the dialog; I am opening another jQuery UI dialog to display a message.

The objective is to close both the dialogs when message dialog Cancel button is clicked.

Razor code is as follows:

Main View

<button id="openModel" onclick="openModel()">

<div id="mainDialog" />

<script type="text/javascript">
    function openModel() {
        $('#mainDialog').dialog({
            open: function () {
                // loading "the secondary view in the model dialog"
                // url: controller-action url to load the second view
                $(this).load('url'); 
            }
        });
    }
</script>

Dialog View

<button id="messageOpener">Verify</button>

<div id="messageDialog" />

<script type="text/javascript">

    $(document).ready(function () {

        $("#messageOpener").click(function () {
            $("#messageDialog").dialog("open");
                return false;
        });

        $("#messageDialog").dialog({
            buttons: {
                Retry: function () {
                    $(this).dialog("close");
                },
                Cancel: function () {
                    // **** ?? must close both dialogs. ****
                }                
            },
            autoOpen: false,
        });
    });

</script>

I have tried following approaches to close the dialogs:

Approach 01:

$(".ui-dialog-content").dialog("close");

Approach 02:

$(this).dialog("close");
$("#mainDialog").dialog("close");

Approach 03:

$(".ui-dialog:visible").find(".dialog").dialog("close");

But all above does not close the dialogs as expected instead produces the following JS error:

Uncaught Error: cannot call methods on dialog prior to initialization; attempted to call method ‘close’
v.extend.error
(anonymous function)
v.extend.each
v.fn.v.each
e.fn.(anonymous function)
$.dialog.buttons.Cancel
r.click
v.event.dispatch
o.handle.u

Re-writing the code in the following way solve the problem..

1. Main View

<button id="openModel" onclick="openModel()">

<div id="mainDialog" />

<script type="text/javascript">

    var $modelDialog = $('#mainDialog').dialog({
        autoOpen: false,
        open: function () {
            // loading "the secondary view in the model dialog"
            // url: controller-action url to load the second view
            $(this).load('url'); 
        }
    });

    function openModel() {
        $modelDialog.dialog('open');    
    }

    function closeModel() {
        $modelDialog.dialog('close');    
    }

</script>

2. Dialog View

<button id="messageOpener">Verify</button>

<div id="messageDialog" />

<script type="text/javascript">

    var $messageDialog;

    $(document).ready(function () {

        $("#messageOpener").click(function () {
            $messageDialog.dialog("open");
                return false;
        });

        $messageDialog = $("#messageDialog").dialog({
            buttons: {
                Retry: function () {
                    $messageDialog.dialog("close");
                },
                Cancel: function () {
                    // [!!]
                    $messageDialog.dialog("destroy");
                    closeModel();
                }                
            },
            autoOpen: false,
        });
    });

</script>
