I have a div that I can drag on mousedown. In Firefox the code works as expected. In IE, however, it does not work anymore.
I noticed that if you put the mousemove event listener on the div that I'm dragging that it will get lost if you move the mouse wildly across the screen. So I decided to put the even on the window.
Now you can move the mouse as fast as you want in FireFox. In IE, however, it moves a little then stops - not reacting at all.
How to disable the copy/drag event for some selected textfield as I want the user to key in instead of copy or drag the required information.
For IE, I done it with the onPaste and onDragEnter Event, but it don't work on Other Browser ...
I had an interesting idea recently to implement on my dynamic site.
I would like to have the users be able to click on object 1 and drag it
overtop of object 2. Object 1 and object 2 should be div tags so that
they could go around anything. When the user starts to drag object 1,
a parcially transparent object 1 appears wherever the mouse goes (we
will call this object 3) and the original object 1 disappears. After
the user lets go of object 1 ontop of object 2, object 3 disappears and
a javascript occurs (i will add this to the script later). If object 1
is let go not ontop of object 2 then the original object 1 reappears
where it used to be and object 3 disappears.
Also, while all this clicking and draging is going on the user should
be able to click and drag to scroll the page.
Unfortunately i have no idea how to do any of this. If anyone could
help me with this it would be appreciated. This is kind of what you
can do to files and folders in Windows XP.
There seems to be a lot out there, but I haven't found a javascript for a click and drag that has been bug free. The last one I had didn't work in Safari.

I am using YUI's Drag and Drop utility to add some drag & drop functionality to a CMS I'm building.
This works just fine and is very easy to set up, but the thing I'm wondering about, how do I restrict the dragging? In other words; how can I make sure an element gets dragged within the borders of, say, some div and not outside them?
As the subject says, is this possible. I'd like to drag a file onto a button and have the filename accesable within that pages javascript.

View 4 Replies View RelatedAfter a good deal of internal development, I've decided this library will do more good in the wild. It works in IE6, Safari 2, Opera 9, Firefox 1.5, and IE5.5/Mac (sort of buggy behavior with text selection in IE5.5/Mac though). It should also work in virtually any version of Gecko, Opera 6+, Safari 1, and IE5+ (anybody who wants to test those, feel free). The scripting is highly efficient, and only exposes two functions globally, Draggable and Droppable. The below code is licensed under the LGPL, though it is available under other licenses per request.
Let me know if you have any issues with it - this is something I'm interested in maintaining. Also, compared to other scripts, such as script.tac.ulo.us, this is much less code (lots of whitespace/comments could be taken out), and more widely supported across browsers.
Other than below, it can be found here: http://www.jasonkarldavis.com/scripts/dragdropable/dragdropable.html

//Copyright (C) 2006 Jason Davis, www.jasonkarldavis.com
//This code is licensed under the LGPL:
//http://www.gnu.org/licenses/lgpl.html
//
// Documentation:
//This script exposes two global variables, Draggable and Droppable. To make an
//element draggable, simply call `Draggable(element)`. This sets the necessary
//CSS properties and event handlers. It also overrides the addEventListener and
//and attachEvent methods (if present) to include the following events:
//onstart(When the element begins dragging)
//ondrag(When the element is being dragged)
//onstop(When the element has stopped dragging)
//You may also assign element.onstart, element.ondrag, and element.onstart to
//add event listeners.
//Lastly, if you need to physically prevent an element from dragging, you may
//call event.preventDefault() from within the onstart handler.
//
//To make an element droppable (have things dragged onto it), call
//`Droppable(element)`. This sets the necessary event handlers and coordinate
//searches. Once again, it overrides addEventListener and attachEvent to
//include the following events:
//onhover(When another element has been dragged over the element)
//ondrop(When another element has been dropped onto the element)
//onunhover(When another element has been dragged off the element)
//As before, you may also set element.onhover, element.ondrop, and
//element.onunhover directly.
//To remove all drop points from the current session, call `Droppable.reset()`.
//
//The event object is also extended with the following properties:
//dragTarget(The element being dragged)
//dropTarget(The element being dropped onto)
//
// Known bugs:
//* removeEventListener and detachEvent do not work with the custom events.
//Workaround: Use direct assignment (element.onevent) instead.
//* There is no way to remove a single drop point.
//Workaround: Call Droppable.reset(), then reinitialize the other drop points.
//* There is no way to remove dragging from an element.
//Workaround: element.onstart = function(event) { event.preventDefault() }
//* Changing position of droppable elements after initialization breaks drop
//Workaround: Static droppables are much faster than moving ones. Either call
//Droppable.reset() and reinitialize often, or ask the author to modify the
//script to account for this (and accept the resulting slowdown)

What im looking for is to have a database hold a list of images ( or numbers that corrospond to images)... that should be easy enough. The part im having trouble with is having these images aligned in a grid which is inside a window /frame/ box on the web page. The user can click and drag and it will move around this collection of images.....
like so (numbers represent images):
5 4 3
6 1 2
7 8 9
so if the user clicked and dragged to the right the images would then look like:
4 3 12
1 2 11
8 9 10
the new images are taken from the database and the user can drag in any direction.
even if its just what this is called that i should search for, ive tried draggable images, scrolling images etc etc
