I have a large form with a image upload field working ok.
Field is defined in model as:
$this->add('filestore/Field_Image','thumbnail_id');
Then I created two tabs inside form:
$tabs=$form->add('Tabs');
$main=$tabs->addTab('General');
$design=$tabs->addTab('Design');
And moved image field to design tab:
$design->add($form->getElement('thumbnail_id'));
Now I can't upload files. When I try I get the following javascript error
Error: cannot call methods on atk4_form prior to initialization; attempted to call method 'submitPlain
Is there any other way to move the field or have upload working again after moving it?
I was trying to use the same method ($design->add($form->getElement('my_element'));) to move a slider into another place on the page. That didn't work - I think it was because the slider input field is not placed on the page the same way as other input fields.
So I tried with the jQuery appendTo-method (I found the hint in a comment from romanish in a documentation page). That worked. But then I experienced the same problem as you - and in the end I gave up and solved the problem by editing the slider-class page.
So I can't help you, sorry, but I guess this points out that there is a general problem related to getting input from moved form elements.

When an HTML editor is used and images are added from the local computer, they are uploaded to a server and a link is obtained to put it in the image src attribute. What happens when the img element is removed from the editor? How would the image be deleted from the server? In this case I understand that the image deletion event could be detected and then call a service to delete it. But what happens if the user adds a new image and leaves the page? How would it be deleted in these cases?
In both cases, if the deletion of the images is not managed, it could happen that the server is filled with unused images. How do you usually solve this problem? How is the proper way to solve this?
That's a nice question there. And yeah, for sure the server would fill up with unused images in some point. I'm not an expert on this but I'll try to suggest something so I can implement it too in my WYSIWYG editor haha. I suppose you have a custom modal for the insertion of the image. Upon clicking the button you could save the image link to an array and at SAVE || on leaving the document edit || on popstate event you could make a regex that checks the innerHTML of the editor for the specific SRC. If is not found then you could push an ajax request with the image name so you can deleteit. For sure there are more efficient and complex ways to achieve that. Such as creating text ranges and track elements on keydown - Backspace(8) / Deletekey(46).
An other way is that you could track the images that are in use. When the document is saved regex out the images in the document, push them to a db table and periodically make a check from the back end so you can delete those that are not in use.
I don't know if my suggestions are helpful or not. I just saw an interesting subject so I jumped in. Cheers mate.
Is there a way to get featherlight.js to trigger on an image itself, as opposed to a surrounding link?
For example, I'm trying this:
$('img.pop').featherlight($(this));
But getting an error:
a.cloneNode is not a function
Should not be a problem. The problem is probably what is this in your code above. That's why my advice to anyone ever reporting a problem is to produce a working example.
I'm trying to put TinyMCE on my website. I figured out how to get it to show up, but I'm lost on how to process the content. In their example, they just have a link that references the top of the page and clicking on it somehow magically causes their dump.php script to execute. I don't understand what's going on here. Here is the link:
http://www.tinymce.com/tryit/basic.php
The "Submit" button at the bottom is really a link in a span element with href="#". The form action is dump.php. I want to know how they configured this to run without an actual submit button. Any help in understanding this is greatly appreciated!
To Get Content From Tinymce You Can Use GetContent Method of Currently ActiveEditor Instance
tinyMCE.activeEditor.getContent();
method is used to getting Content .. to Set The Content
tinyMCE.activeEditor.setContent("I Want Text To Be in Tinymce");
to find a perticular element in tinymce get body and find element
var body = tinyMCE.activeEditor.getBody();
$(body).find("#elem_id")
to get a full html
tinyMCE.activeEditor.getDoc().documentElement.innerHTML
hope that helps ..
Since I use PHP, I found this which is also useful:

My registration is using Spring forms and validates the data after submit, the form:errors will be printed out if there are errors. I need to scroll the page down to the first form:error so the user hasn't to search for the error, is there a way to do that?
cheers
I haven't tried any of them, but I can think of two possible ways:
With Javascript. Spans generated by < form:errors /> have a class (I don't remember at the moment) or you can force on using cssClass attribute. Would be very easy using this jQuery plugin to scroll to the first one.
Without Javascript. This will be a lot more difficult and I'm not sure it will work:
In your controller, instead of returning a direct view you must do a redirect to something like /myForm#error.
In order to don't lose your model, you must use FlashMap attributes.
"Subclass" < form:errors /> tag. It must have the same behavior but it has to include an anchor named error on the first error of the page.
I think you can do it with anchors. -- But you need to implement it by your own.
My idea it to put anchors on all input files. And then have some java script that is able to scoll to an anchor. This java script is invoked on page load if the error object contains errors. -- This errors contains the name of the field. So if you have some schama for naming the anchors it should be possible to invoke the jump to an anchor script with the name of the field hat has an error.
The object is to Show-Hide text located under their respective Titles, so a User reads the title and shows or hides text belonging to that title if the User wants to read more.
I tried whatever I could find so far on here, we're talking dynamically setting text coming from a spreadsheet, can't use IDs, must work with .class, must be missing something, I have this piece of code:
... html.push('<div class="comments">' + comment + '</div></div></div>');
but when I try this Show-Hide code nothing happens, even if the error console shows nothing. Basically I want to Show-Hide the .comments class divs with a show-hide toggle link located under each of them. I say them because the .comments divs are reproduced dynamically while extracting text coming from Google spreadsheet cells/row (one .comments div per spreadsheet row). I tried .next, child and parent but they all divorced me so I dunno looks like a dynamic issue. So far I only managed to globally toggle all divs to a visible or hidden state but I need to toggle independantly individual divs.
I prefer a jQuery solution but whatever worked so far was achieved with native javascript.
Note: If a cross-browser truncate function which would append a more-less link after a number of words (var) in each .comments divs would be easier to implement then I would gladly take that option. Thx for any help, remember I am still learning lol!
I have been working on an entirely JS UI project and have brought myself to using $('', { properties }).appendTo(BaseElement) to work best for adding HTML elements because it appropriately manipulates the DOM every time.
If you are having good luck with push elsewhere, however, breakpointing on the line where you do your $('.class').hide() and see what $('.class').length is. Alternately, you can just add alert($('.class').length) to your code if you are unable to breakpoint the code. If it is 0, then your elements have not been properly added to the DOM. Changing to append will ensure they are part of the DOM and therefore targetable via JQuery.
