I want to make a webpage that allows a user to select and copy an HTML entity with a single click, and using ZeroClipboard should be good enough for this. I want to have tens, maybe even hundreds of copyable HTML entities on the page, so I would prefer not to have a ZeroClipboard client for each entity. The solution I came up with is to have a table of HTML entities where each td contains a different HTLM entity, and captures onmouseover, so I can determine which HTML entity the user wants. Then I glue the ZeroClipboard to this table to capture the onclick. By default the ZeroClipboard object has z-index 99 so it sits over the table. Unfortunately since the ZeroClipboard object has nothing to do with the table semantically the events can't propagate to the td which is hidden underneath.
Is there a way to capture the onclick on the ZeroClipboard object (embed) with a z-index of 99, and also capture the onmouseover on the td that sits underneath with a z-index of 1? Do I need to find the coordinates of the mouse cursor to do this? I would rather not do that because a) it's messy and b) technically impossible with the W3C specifications.
I've frozen two copies of my current code:
ZeroClipboard embed z-index=99 : http://www.aidansean.com/physics/symbols_static.php
(This can copy the "..." contents of the box in the upper left.)
ZeroClipboard embed z-index=-99: http://www.aidansean.com/physics/symbols_static_2.php
(This can change the "..." contents of the box in the upper left.)
I want to combine the functionality of both of these pages. Any help greatly appreciated!
Finally, there you go. Some other options I tried, didn't work. Is this a helpful solution? :)

I have a calendar-like view that shows a table with one column per day of the week (see this image). Each row represents a specific thing that can be booked for a time. The idea is now that a booking can be extended by dragging the outer edge to the next day in the table, or shortened the same way. The active booking has a span on each side of the cell that is supposed to be the handle for dragging.
My main problem now is that the usual drag & drop features in browsers don't seem to fit my situation. I don't want to drag something and drop it anywhere else, I just want to drag to extend the item.
Is this still something that can be done with the usual HTML5 drag&drop feature or some generic drag&drop library? Or is there any other way to achieve this? Any pointers on how to approach this problem?
I'm using React for this, which might make some solutions difficult to integrate if they manipulate the DOM directly.
ummm not sure what to do here , I thinks its unlikely the link will change soon , I can describe the repo 'Allows individual or group selection of items using the mouse. Click and drag to lasso multiple items, hold the cmd/ctrl key to select non-adjacent items'. I can briefly describe what the lib code does: uses keydown, keyup and mousedown listeners to create an overlay and detect covered nodes in the DOM .
I am working on a WYSIWYG editor (customising someone else's code) and have encountered a few problems that I just can't seem to overcome.
So far I have been able to get most custom divs working, but I am having some trouble with a few things:
Problem 1: If the cursor is before a div element, I am able to press delete and begin to remove the contents of the div without removing the actual div itself. This is how the element should look within the WYSIWYG for example:
But after pressing delete when the cursor is before the element, I get the following:
How can I check if the next element is this custom div and cancel a delete key press?
Problem 2: I am also able to press backspace after an element, which causes any text after the element to appear inside it, like so:
How can I check if the previous element is my custom div and cancel a backspace key press?
Problem 3: When inside a section (where the 'put content here' text is), I am using a div with the attribute contenteditable="true". Every time I press 'enter' within this div, a new <div> tag is created, rather than a line break tag (<br>). How can I force a line break tag to be created instead of a div element?
I have looked far and wide on stackoverflow and have yet to find a proper solution to the problem that is cross-browser.
Disclaimer: I am a CKEditor core developer.
If you want to customise this there are three ways:
You can spend few months (or more) on learning about contenteditable, ranges, selection and all that stuff and trying to implement your custom handlers. You could of course spend only one week or month on that, but the result won't be great, believe me.
You can choose good, existing WYSIWYG editor.
You can lower your expectations regarding the expected behaviour ;).
Now, if you would decide to use CKEditor there's one new feature called Widgets which was introduced in recently released CKEditor 4.3 beta (4.3 stable is going to be released in max. 2-3 weeks). As far as I can see it may be very helpful in your case. Check out the Introduction to Widgets guide. In very short - it is possible to configure how enter key behaves in so called "nested editables" as well as to secure integrity of your custom markup.
I wrote a TinyMCE plugin for Wordpress that drops a prepared bit of HTML into the textarea when a button on the toolbar is clicked. This is to assist in formatting some relatively complicated elements.
I would like for this piece of HTML to be wrapped in some sort of container that TinyMCE recognizes and allows for easy selection or deletion if needed.
Currently, the only way to delete an individual element is by erasing all of the information each individual "sub element" contains. I can't seem to find any information in the API regarding manually assigning an element as a singular combined object. As far as behavior goes, think "resize frame" or something similar (only this won't need to have any resizing capabilities).
Any ideas?
If you want to wrap text/html inside an element of your choice (i used a span here) at the current cursor position of tinymce editor instance ed you can simply do
ed.execCommand('insertHTML', false, '<span class="custom_to_delete">My_Text</span>');
Folks,
I need a solution that allows drag-and-drop cell over the table.
The cells can be of different colspans, so when the cell is dropped into the middle of another cell, which is bigger, the following steps should be performed:
Another td element is created, which is equal in width to the draggable element.
Cells on left and right of new td element automatically adjust their width.
Now I use JQuery drag-and-drop plug-in. It allows to drag elements, but becomes a bit awkward when it comes to manipulating DOM elements on the part of droppable element.
Could anybody propose some library where this kind of behaviour is implemented?
DragTable might be a good starting point.
Not sure if it supports tables, but I have used link text before and it worked fairly well for me
I've been googling and trying this for a good while now, but comes nowhere. So here goes:
What I want to do is to drop text on a DIV tag and handle that with JavaScript. Something along these lines:
<script type="text/javascript">
function handleDrop(sender, args)
{
$('#theDiv').html(args.textfromdrop);
}
</script>
<div id="theDiv" ondrop="handleDrop()" />
<br/>
<p>
This is some simple text. Draggable?
</p>
So, on this page I want to be able to drag contents from the paragraph for example to the div and it would handle the drop and change it's appearance accordingly (Or maybe just display that text, as long as it would handle it!). I've been trying with jQuery, but it seems to be a whole other model, and I can't set all my potential draggables as such because they should be able to come from everywhere. Is this even possible?
EDIT: Please correct me if I'm wrong, but these droppables all require a draggable to be dropped at it, right? What I would want is that you can drop text, pure text, from a page that you don't have any control of. This might sound weird, but it's for a firefox extension where you can drag content from a page to another page that resides in the side bar.
I would recommend using an established Javascript Library such as jQuery or YUI.
Have you considered creating a hidden textarea (ie with css style visibility:hidden) overlapping the div in question? Then check for drops with the onchange JavaScript event, or if that doesn't work, periodically the textarea's value for non-empty strings. I'm guessing your mileage will vary depending on the browser and operating system.
Or if you prefer Prototype like I do: http://wiki.github.com/madrobby/scriptaculous/droppables
EDIT: Based on your revised question: No, there's no way to allow a user to drop text from one page to another page. Not unless you do decide to build a FireFox extension like you were saying. Even if you could find a way around the security issue where you cannot script a page that's not under the same domain, you can only drag and drop DOM elements within the window/iFrame they're in.
I have done this before and it CAN be done without any library with some effort.
I've built the following methods:
Method that tracks your mouse movements.
Method to read and pass the content when you drop.
Used onmousemove and onclick events for the drag and drop methods.
OnMouseOver for the div area where you'd like to drop the text - to detect whether the pointer is over the container (div) or not.
Finally after dropping the text I deleted the original content (if needed) using innerHTML so it looks like it has been moved.
You can pretty much achieve a Windows like drag and drop functionality with this. I used it for drag and drop images, icons, etc.
If you need help with the coding I can give you some guidance, but most of it you will find if you Google around a little, then all you need to do is make them work together.
