Jquery-ui Tabs Open dialog box on tab click (stop code)

This is my code. I am trying to stop the clicked tab from loading until i get a response from the dialog box. Also if i click cancel, i wan to return to the previously selected tab. currently the way i have it setup it creates a loop (which i broke with my lame code).
As seen in my jsfiddle example the code does stop. However, you will notice in the backround that the tab does change to the clicked one, so if you click cancel the backround will flash. i am trying to avoid that.
Thanks.
My Fiddle
//
var runOnceDammit;
$(document).ready(function() {
$(".hideT").button();
$("#tabs").tabs();
$("#tabs").tabs("disable", "#tabs-4");
$('.ms-formtable').appendTo($('#tabs-1'));
$("#tabs").on("tabsbeforeactivate", function(event, ui) {
if (runOnceDammit == true) {
runOnceDammit = false;
return;
}
var active = $("#tabs").tabs("option", "active");
var dialResults = $.when(showDialog());
dialResults.done(function(data) {
if (data) {
$('.ms-formtable').appendTo(ui.newPanel);
if (ui.newPanel.is("#tabs-2")) {
//do stuff
} else if (ui.newPanel.is("#tabs-3")) {
//do stuff
} else if (ui.newPanel.is("#tabs-1")) {
//do stuff
}
return;
} else {
ui.newTab.blur(); //trying to remove higlight from tab
runOnceDammit = true
$("#tabs").tabs({
active: active
}); //activate previous tab
return;
}
});
//return;
});
}); //End DocReady!

function showDialog() {
var dfd = $.Deferred();
var results;
$('#dialog').dialog({
dialogClass: "no-close",
title: "Fanciful Dialog Box",
modal: true,
draggable: false,
buttons: [{
text: 'Confirm',
icons: {
primary: "ui-icon-check"
},
click: function() {
results = true;
$(this).dialog('close');
}
}, {
text: 'Cancel',
icons: {
primary: "ui-icon-cancel"
},
click: function() {
results = false;
$(this).dialog('close');
}
}],
close: function(event, ui) {
dfd.resolve(results);
}
});
return dfd.promise()
}

Consider the following:
<div class="section" id="section-1">
Tab 1
</div>
<div class="section" id="section-2">
<a name="myTab-1"></a>
</div>
<script>
$("#myTab-1").click(function(event){
event.preventDefault();
// Do a thing
return true;
});
</script>
This jQuery code will bind an anonymous function to the click event. The function takes a JavaScript Event Object as an attribute. Events have some methods to them, such as, .preventDefault(). This allows you to interrupt the default event and execute your own code. Using return true will return the default behavior after your code has been run.
I answered a similar question: confirm form submit with jquery UI
I found it better to resolve with the result. It seems that .resove() will work out better this way when it comes to the .done() code.
Working example: https://jsfiddle.net/Twisty/e2djqx08/
The key, I think, was to assign the active tab properly in your cancellation code.
JavaScript
function showDialog() {
var dfd = $.Deferred();
var results;
$('#dialog').dialog({
dialogClass: "no-close",
title: "Fanciful Dialog Box",
modal: true,
draggable: false,
buttons: [{
text: 'Confirm',
icons: {
primary: "ui-icon-check"
},
click: function() {
$(this).dialog('close');
dfd.resolve(true);
}
}, {
text: 'Cancel',
icons: {
primary: "ui-icon-cancel"
},
click: function() {
$(this).dialog('close');
dfd.resolve(false);
}
}]
});
return dfd.promise();
}
$(function() {
$("#tabs").tabs().tabs("disable", 3);
$('.ms-formtable').appendTo($('#tabs-1'));
$("#tabs").on("tabsbeforeactivate", function(e, ui) {
e.preventDefault();
console.log("EVENT: Prevent Default");
var self = $(this);
var revertToTab = ui.oldTab;
var revertToPanel = ui.oldPanel;
var sendTo = ui.newTab;
var sendToPanel = ui.newPanel;
console.log("EVENT: When Dialog is closed.");
$.when(showDialog()).done(function(data) {
if (data) {
console.log("INFO: Dialog Confirmed.");
$('.ms-formtable').appendTo(ui.newPanel);
if (self.is("#tabs-2")) {
//do stuff
} else if (self.is("#tabs-3")) {
//do stuff
} else if (self.is("#tabs-1")) {
//do stuff
}
return;
} else {
console.log("INFO: Dialog Cancelled");
self.blur();
$("#tabs").tabs("option", "active", revertToTab);
return false;
}
});
});
});
In my tests, I continued to find the active tab panel loading while the dialog was active. This did not happen when I used $("#tabs").tabs("option", "active", revertToTab);.
Hope that helps.

Javascript functions in custom namespaces

It is possible to declare 2 more functions in main function like this ?
var jquery4u = {
init: function() {
jquery4u.countdown.show();
},
countdown: function() {
show: function() {
console.log('show');
},
hide: function() {
console.log('hide');
}
}
}
jquery4u.init();
and i receive the following error: Uncaught SyntaxError: Unexpected token ( on this line "show: function() {"

Remove the function from the right of the countdown (demo)
var jquery4u = {
init: function() {
jquery4u.countdown.show();
},
countdown: {
show: function() {
console.log('show');
},
hide: function() {
console.log('hide');
}
}
}
jquery4u.init();
Next time, use jsFiddle to make a demo and click the "JSHint" button.

Actually, none of this will work. Unless you make countdown an object or you treat its sub-functions as proper functions.
Why: Under countdown, you created an instance of object not a function.
var jquery4u = {
countdown: function() {
show = function() {
console.log('show');
}
hide = function() {
console.log('hide');
}
jquery4u.countdown.show();
}
}
The above code is a valid code so it is possible. Unfortunately it will not return anything.
The proper way to do this is in this format:
var jquery4u = {
countdown: {
show: function() {
console.log('show');
},
hide: function() {
console.log('hide');
}
}
}
This will work. You can try it out by calling:
jquery4u.countdown.show();

Customised confirm jquery dialog across project

I have to create a confirm modal box of jquery that works as default confirm box that return true or false and works across the project.
I call it this way....
var result = confirm("Are you sure you want exit");
if(result == false)
return false;
else{
//somethings are done here
}
and in a Main.js written it's implementation as following ..
function confirm(message){
$("#alert_cust_message").html(message);
var returnValue = false;
$("#myAlert").dialog({
modal: true,
minHeight: 100,
buttons: {
"OK": function()
{
$( this ).dialog( "close" );
returnValue = true;
},
Cancel: function()
{
$( this ).dialog( "close" );
returnValue = false;
}
}
});
$("#myAlert").parent().css('font-size','9pt');
return returnValue;
}
Now the problem that i am facing is about the return value ...
I am not get the expected returns, I think it is due to asynchronous dialog.
Now can this be solved easily ?
Any help will be appreciated .. Thanks

You need to use a callback
function confirm(message, callback) {
$("#alert_cust_message").html(message);
var returnValue = false;
$("#myAlert").dialog({
modal: true,
minHeight: 100,
buttons: {
"OK": function () {
$(this).dialog("close");
callback(true);
},
Cancel: function () {
$(this).dialog("close");
callback(false);
}
}
});
$("#myAlert").parent().css('font-size', '9pt');
}
then
confirm('some message', function (result) {
if (result) {}
})

To apply .delay() on mouseenter in my plugin

I got a div, that on mouseenter, is suppose to show another div. I'm not sure how to achive this in a plugin. This is my code and what I have tried so far.
Code: JsFiddle
<div class="hover-me"></div>
<div class="show-me"></div>
var Nav = {
hover_me: $('.hover-me'),
show_me: $('.show-me'),
init: function() {
Nav.toggle_display();
console.log('init');
},
toggle_display: function() {
Nav.hover_me.mouseenter(function() {
Nav.show();
});
Nav.hover_me.mouseleave(function () {
Nav.hide();
});
},
show: function() {
Nav.show_me.fadeIn();
},
hide: function() {
Nav.show_me.fadeOut();
}
};
I tried to do this, without any luck.
Nav.hover_me.mouseenter(function() {
Nav.delay(1000).show();
});

see Jimbo's comment:
var Nav = {
// [...]
timeoutId: undefined,
// [...]
};
Nav.hover_me.mouseenter(function() {
Nav.timeoutId = setTimeout(function() {
Nav.show();
}, 1000);
});
Nav.hover_me.mouseleave(function () {
if (Nav.timeoutId) { clearTimeout(Nav.timeoutId); }
Nav.hide();
});

missing : after property id in JQuery.inArray(value, array)

I'm getting a firebug error:
missing : after property id
error source line:
if(jQuery.inArray(mmDialogButton.CANCEL, buttons)){
This is the surrunding code:
Edited post with update as I was unclear.
I am trying to create a framework for creating dialogues for a project.
In the dialogs there can be four predefined buttons.
The mmDialogButton is my attempt to an ENUM class.
The if statement is there to enable the buttons the user wanted to use in the dialog.
Here is some more code to illustrate.
mmDialog.js
...
function mmDialog(title, spawnerId, widget, buttons){
...
$dialog.html(widget.getInitialHTML())
.dialog({
autoOpen: false,
title: title + ' <img id="myJquerySpinner" />',
buttons: {
if(jQuery.inArray(mmDialogButton.CANCEL, buttons)){
Cancel: function() {
$( this ).dialog( "close" );
},
}
if(jQuery.inArray(mmDialogButton.NEXT, buttons)){
"Next": function() {
widget.doNext();
},
}
if(jQuery.inArray(mmDialogButton.PREVIOUS, buttons)){
"Previous": function() {
widget.doPrevious();
},
}
if(jQuery.inArray(mmDialogButton.OK, buttons)){
"Ok": function() {
widget.doOk();
}
}
}...
mmDialogButton.js
function mmDialogButton(){ // Constructor
}
mmDialogButton.CANCEL = function() { return "mmDBCancel"; };
mmDialogButton.OK = function() { return "mmDBOk"; };
mmDialogButton.NEXT = function() { return "mmDBNext"; };
mmDialogButton.PREVIOUS = function() { return "mmDBPrevious"; };
jsp/html page
var title = "Test Dialog";
var spawnerId = "myJqueryStarter";
var mmDialogButtons = new Array();
mmDialogButtons[0] = mmDialogButton.CANCEL;
mmDialogButtons[1] = mmDialogButton.OK;
mmDialogButtons[2] = mmDialogButton.NEXT;
mmDialogButtons[3] = mmDialogButton.PREVIOUS;
myPublishWidget = new mmPublishWidget();
myDialogPublishWidget = new mmDialogWidget(myPublishWidget);
myDialog = new mmDialog(title, spawnerId, myDialogPublishWidget , mmDialogButtons);

This:
buttons: {
if(jQuery.inArray(mmDialogButton.CANCEL, buttons)){
Cancel: function() {
$( this ).dialog( "close" );
},
should probably be:
buttons: (function() {
if(jQuery.inArray(mmDialogButton.CANCEL, buttons))
return {
Cancel: function() {
$( this ).dialog( "close" );
}
};
return null;
})()
though it's hard to tell. What it looks like you're trying to do is conditionally set that "buttons" property to some object with a labeled handler (that little "close" function). However, the code you posted is syntactically nonsensical. The change I made wraps the "inArray" test in an anonymous function that returns the button object only when that test is true.
Again, I'm just guessing that that's what you were trying to do.

I think you mean to execute the "close" only if CANCEL is in buttons, if it's the case you can write:
buttons: {
Cancel: function() {
if(jQuery.inArray(mmDialogButton.CANCEL, buttons)){
$( this ).dialog( "close" );
}
},
....
EDIT:
you can define the buttons dictionary beforehand as you like, the pass it to .dialog(:
dialog_buttons = {}
if(jQuery.inArray(mmDialogButton.CANCEL, buttons)){
dialog_buttons[Cancel] = function() {
$( this ).dialog( "close" );
}
}
if(jQuery.inArray(mmDialogButton.NEXT, buttons)){
dialog_buttons["Next"] = function() {
widget.doNext();
}
}
if(jQuery.inArray(mmDialogButton.PREVIOUS, buttons)){
dialog_buttons["Previous"] = function() {
widget.doPrevious();
}
}
if(jQuery.inArray(mmDialogButton.OK, buttons)){
dialog_buttons["Ok"] = function() {
widget.doOk();
}
}
$dialog.html(widget.getInitialHTML())
.dialog({
autoOpen: false,
title: title + ' <img id="myJquerySpinner" />',
buttons: dialog_buttons
}...
