CKEDITOR : Remove last undo from stack CKEDITOR

My Question is
How to remove the last undoing from undoing stack?
I'm Doing something in CKEditor.And I'm using
editor.fire('lockSnapshot');
and
editor.fire('unlockSnapshot');
My Original HTML content is
After Change Something(put del/ins tag using MY CODE)
And I add something in the editor and doing undo it will change like this.
And this is my code.
editor.fire('lockSnapshot');
$(currentSpanNode).after('<ins class="ice-ins ice-cts">' + spanInnerText + '</ins>');
$(currentSpanNode).after('<del class="ice-del ice-cts">' + spanOuterHTML + '</del>');
$(currentSpanNode).remove();
editor.fire('unlockSnapshot');
'currentSpanNode' have a particular span Node.
I want to know..
Is there any possible way to Remove/Update Stack of undo?
If possible tell me the way.
Please, anyone get me out of this issue.

Jquery, cannot access css properties of dynamically generated element

I am using jQuery to append elements to a div, and all works fine.
var new_div = $('<div>My stuff</div>');
new_div.appendTo("#container");
However, I'd like the div to appear by fading in, instead of abruptly.
I notice though that I get an error when I try to access graphic properties on my dynamically generated element. So this, for example fails:
new_div.hide().fadeIn();
The console reports the following error:
TypeError: jQuery.curCSS is not a function
Do I understand this correctly, that this fails because current css properties are not defined for the dynamically generated element? Or what else can be goingg wrong?
Important edit
Additional checking and working on this pointed out to a complete misunderstanding from my part. This has nothing to do with the fact that the element was dynamically generated. I got the same thing by calling fadeIn() on whatever element.
I sincerely apologize!
I still didn't get, though, why this happens

Adding elements to the DOM takes some time, miliseconds maybe, but it's still a reason for jquery not be able to find the element.
This process might be even slower if the DOM is a large html page.
Write your code like this:
var new_div = $('<div>My stuff</div>');
new_div.appendTo("#container");
setTimeout( function(){
new_div.hide().fadeIn();
} , 150); // 100 could be also good
It might be enough time for jquery to catch the element.

I would add an id to keep track of all elements I'm creating (just my preference, but it makes it easier to code it).
var new_div = '<div id="myNewDiv1" style="display:none;">My Styff</div>'
$('body').append(new_div);
$('#myNewDiv1').fadeIn();

It does seem to be a compatibility question, although I wasn't able to figure out exactly why and how to fix it.
Adding this code fixes the problem though:
jQuery.curCSS = function(element, prop, val) {
return jQuery(element).css(prop, val);
};

Cannot use css() on dynamically created div in custom plugin

I have recently taken up learning how to make a jQuery plugin. This is my first attempt at just creating something that is very simple. I am still relatively new to jQuery and have come into a bit of a bind when it comes to selecting dynamically created content. In this scenario I am attempting to select a div I created within the plugin.
I have made a jsFiddle here.
I have perused many posts about selecting dynamically created div's and most of them are solved either using on or a callback function. And I am not sure that those can be applied in this situation.
I think the issue occurs at this point in the code:
$element.append("<div class=\"gifLoader\"></div>");
$gifLoader = $element.find('.gifLoader');
$gifLoader.css("bacground-image", "url(\"" + plugin.settings.gifSrc + "\")");
plugin.settings.callback.call(this);
Is there some way I can use a callback function like you would with methods like fadeTo? Also, if anyone cares to comment. I would really appreciate some feedback on the layout of my plugins. I don't fully comprehend what it is I am doing when making a plugin, I am just hoping to learn how to use Javascript and jQuery without the coding looking so clunky. (Before I just had anonymous functions within anonymous functions)

You have one typo, and one error: bacground-image => background-image, and src() => url()
Change
$gifLoader.css("bacground-image", "src(\"" + plugin.settings.gifSrc + "\")");
To
$gifLoader.css("background-image", "url(\"" + plugin.settings.gifSrc + "\")");

When you are creating a dynamic element using javascript or jquery, that element does not reflect in your DOM straight away. If you take a look into the HTML that is generated using the developer tools you'd find before: and after: tags appended with your HTML.
The best way to realize the problem is to either specify the background-image when you are creating the div like:
$("#element").append("<div class='gifLoader' style='background-image: url('" + plugin.settings.gifSrc + "')'></div>");
Otherwise if you are looking to change the background-image on some kind of user interaction, you can go for this:
$("#element").append("<div class='gifLoader' id='someID' someEvent='transform(someID)'></div>");
And then have function transform() defined somewhat like:
function transform(elementID) {
$("#" + elementID).css("background-image", "some image URL");
}

Javarscript issues with dynamic tooltipster

I'm using Tooltipster which seems to be a nice jquery plugin.
Regardless I need to have my tooltips dynamic, which I don't believe should be that difficult. However I wrote a script and maybe it's because I'm tired or I don't know the simplest of javascript. Probably a combination of both.
I can't seem to get around this particular error. TypeError: $(...).tooltipster is not a function.
Here is the basic javascript code:
$("img#box_image[data-img-number]").hover(function(e) {
e.preventDefault();
i = $(this).attr("data-img-number");
var w = "http://trailerbrokerimages.s3.amazonaws.com/pics/" + i ;
window.console.log('before tool');
window.console.log('before tool ' +w);
tool(w);
});
var tool = function (w) {
$('.tooltip_two').tooltipster({content: $('<span><img style="height:191px; width:256px;"src="http://trailerbrokerimages.s3.amazonaws.com/pics/'+w+'" /></span>')});
An example of the code can be found at http://www.trailerbroker.com/go/listings/view/219
I suspect it's lame mistake on my part, thanks.

You have the same id box_image for multiple elements.
I understand that you're trying to make it unique by appending the data-img-number, but this won't work, as there's no way you can do this at run time unless your explicitly specifying different hover handlers.
Instead you could attach the hover handler to a class.
Add a class="box_image" to your <img /> elements and attach the hover as follows,
$(".box_image").hover(//rest of your code here//)
This should give you the desired functionality.

I solved this problem by using twitter bootstrap popover. Don't waste your time with tooltipers.

Is it possible to make a change with jQuery and then immediately reverse that change?

I have a pretty specific scenario where I would like to select all elements with jQuery, make a CSS change, save the elements, then reverse the change I made.
The Goal
I created a jQuery plugin called jQuery.sendFeedback. This plugin allows the user to highlight areas of the screen, as shown in this demo. When they submit their feedback the plugin grabs all the HTML on the page and dumps it into a callback function. Like so:
$('*').each(function ()
{
$(this).width($(this).width());
$(this).height($(this).height());
});
var feedbackInformation = {
subject: $feedbackSubject.val(),
details: $feedbackDetails.val(),
html: '<html>' + $('html').html() + '</html>'
};
if (settings.feedbackSent)
settings.feedbackSent(feedbackInformation);
The callback function accepts this feedback information and makes an AJAX call to store the page HTML on the server (this HTML includes the red box highlights the user drew on the screen). When someone from tech support needs to view the user's "screen shot" they navigate to a page that serves up the stored HTML so the developer can see where the user drew their highlights on the screen.
My original problem was that different screen resolutions made the elements different sizes and the red highlights would highlight the wrong areas as the screen changed. This was fixed pretty easily by selecting all elements on the page and manually setting their height and width to their current height and width when the user takes the snap shot. This makes all the element sizes static, which is perfect.
$('*').each(function ()
{
$(this).width($(this).width());
$(this).height($(this).height());
});
The Problem
The issue with this is that when the plugin is done transmitting this HTML the page currently being viewed now has static heights and widths on every element. This prevents dropdown menus and some other things from operating as they should. I cannot think of an easy way to reverse the change I made to the DOM without refreshing the page (which may very well end up being my only option). I'd prefer not to refresh the page.
Attempted Solution
What I need is a way to manipulate the HTML that I'm sending to the server, but not the DOM. I tried to change the above code to pull out the HTML first, then do the operation on the string containing the HTML (thus not affecting the DOM), but I'm not quite sure what I'm doing here.
var html = '<html>' + $('html').html() + '</html>';
$('*', html).each(function ()
{
$(this).width($(this).width());
$(this).height($(this).height());
});
This did not work. So either I need to be able to manipulate the string of HTML or I need to be able to manipulate the DOM and undo the manipulation afterward. I'm not quite sure what to do here.
Update
I employed the solution that I posted below it is working beautifully now. Now I am wondering if there is a way to statically write all the css for each element to the element, eliminating the need for style sheets to be referenced.

I think you are mostly on the right track by trying to make the modifications to the HTML as a string rather than on the current page for the user.
If you check this post, you might also want to follow the recommendation of creating a temporary <div> on the page, cloning your intended content to the new <div> ensuring it is invisible using "display:none." By also putting a custom Id on the new <div> you can safely apply your static sizing CSS to those elements using more careful selectors. Once you have sent the content to the server, you can blow away the new <div> completely.
Maybe?

After much pain and suffering I figured a crude but effective method for reverting my modifications to the DOM. Though I hadn't gotten around to trying #fdfrye's suggestion of cloning, I will be trying that next to see if there is a mroe elegant solution. In the meantime, here is the new code in case anyone else can benefit from it:
$('*').each(function () {
if ($(this).attr('style'))
$(this).data('oldStyle', $(this).attr('style'));
else
$(this).data('oldStyle', 'none');
$(this).width($(this).width());
$(this).height($(this).height());
});
var html = '<html>' + $('html').html() + '</html>';
$('*').each(function () {
if ($(this).data('oldStyle') != 'none')
$(this).attr('style', $(this).data('oldStyle'));
else
$(this).removeAttr('style');
});
When I'm looping through every element and modifying the css, I log the original value onto the element as data. After I assign the DOM HTML to a variable I then loop through all elements again and restore the style attribute to its original value. If there was no style attribute then I log 'none' to the element data and then remove the style attribute entirely when looping through again.
This is more performance heavy than I wish it was since it loops through all elements twice; it takes a few seconds to finish. Not horrible but it seems like a little much for such a small task. Anyway, it works. I get a string with fixed-sized HTML elements and the DOM goes back to normal as if the plugin never touched it.
