All the examples that I've seen with draggable elements have a specific destination where the draggable element can be dropped. Is it possible to drop the element anywhere on the screen without specifying the destinations?
I have a map (ThinkGeo) with some specific areas coming from the database. when the user clicks/touches those areas, I'm showing popups with description of those areas. The popup is nothing else than a div that I'm showing and hiding accordingly.
The user wants to be able to move around the popup div on the map. Is this even possible?
Certainly possible and pretty easy with jQuery UI:
$("#elementId").draggable();
And a shim for touch events:

I'm looking for a script that will allow a user to pick an image in an HTML page and drag it to a new location while allowing the other page's element to align around it.
While dragging the image should be completely visible (there are many scripts, like TinyMCE and CKeditor) which don't show the image while dragging and only show its new location and the elements around the dragged image after dropping it.
And just to be clear, the image is using the same z-index as the rest of the page (its inline).
I hope I was clear enough, let me know otherwise.
Something like jQuery Masonry? http://masonry.desandro.com/
I have a textbox, a div, and an image.
Do we have any way to do like this:
When I drag that image into the div. (The image don't need to move, just like we left click on it, and drag it to anywhere, but it never move.)
The div show the image. (Duplicated 1 image into the div)
The text show URL of that image.
Do you have any idea or article(s) on doing this thing?
I've never coded drag drop in my life, but I know Step 2 is just set HTML for the div, and Step 3 is just get image src. However, on Step 1, how do I know when "the image into the div and the mouse release?"
I know jQuery UI, it's not the dragable from jQuery UI, cause the draggable makes object move. I don't want it move. Can you try click on any image on this stackoverflow website, or any link. Then you hold your mouse and drag it. Try drag a link into the search box at top, and you get the link. Thats what I want. Not the dragable of jQuery UI to make the object move.
You can do all of this with the dragable feature in jQuery. I noticed in a comment you mentioned that you don't believe this will work because it actually moves the image but there are more than just the default options! Take a look at the clone helper attribute.
Here's about as close of an example as there is and it sounds like you already know how to handle the rest (getting the src attribute, etc.).

JQuery draggable allows you to leave the original in its place while dragging through the use of Helpers. See this url and try dragging the top grey boxes around. The two on the right use helpers, leaving the original in place.

Using this in conjuntion with the link Artsemis provided will do the trick
Dragging an image into your address bar is a function of the web browser, not JS or the page you are viewing. You will want to use jquery draggable or something like it.
I'm doing a visual editor using HTML5 Drag and Drop and i need to drag an element set as draggable to a div who acts as a container.
Some browsers provides a kind of preview image that represents the element while i'm dragging it, and when i let the element in the container with the drop event, i need to get the position where the user wants to put him. The problem is that i don't know the position of the preview ghost provided by browsers, so i don't know where exactly the element should be positioned.
I used the mouse position but it's not what i wanted, because the mouse position is not ever the same as the preview's. Is there a way to get the current position of the preview of a dragging element?
Have you considered using jQuery UI to do your DnD? I'm not sure if you've considered that or not, but here are some resources that might help you in-case you do choose to do the jQuery UI route:
jQuery UI Draggable (also see Droppable)
jquery ui drag/drop getting position from multiple draggables
For example on a drag and drop scenario.. I would love to be able to use the onmouseover of the thing we are dragging to, but unfortunately, the design calls for a ghost (copy of what is being dragged) which will surround the area of the mouse pointer. So the cursor is moused over the ghost the whole time.
Are you able to use jQuery? If so, I would look into jQuery UI to handle both your drag and drop events. Since you can make a ghost copy of what you are dragging without disrupting where you drop it.

For Firefox 3.6+, Chrome and Safari, you can use pointer-events: none;
jsfiddle.net Example
Original Post from pixelastic.com
When one HTML element is over another one (like when positioning an
element using position:absolute), you usually can't click through the
top element to access the bottom element.
That's used as a common
technique to prevent the right click on images by some sites (like
Flickr). They just add an empty transparent div over their images to
prevent the lambda user from right clicking and saving the image.
Sometimes, when integrating complex designs, you need those additional
layers, but you also want the user to be able to click through them,
as if they weren't there.
Just use the pointer-events:none css
property to allow click events to go through the element.
This is only
supported by Firefox 3.6+, Chrome and Safari for now.
I have seen a feature on a site I would like to emulate. I have intermediate php skill but am a novice javascript user. The feature is the site content displayed in divs which can be moved around on the screen and their position saved using cookies. This site: [url]www.nowgamer.com[/url] is where I saw it (latest podcasts, videos, reviews etc with filter)
How would I go about achieving this through javscript? I want to know how to connect javascript with the cookie so that the positions of the square divs are saved, as are the preferences of the content filter on each div. How can I achieve this?
Would this be a big job? Thank you for any help, I am working independently on this in my spare time so your contribution with advice is my lifeline.
As Zoidberg commented, its easy with JQuery or Yui, or any other javascript library that provides drag & drop functionality. They are almost easy to configure, checking at demo they give. They also expose certain events like beforeDrag, afterDrag, onDrop, etc. where you can fire a simple js function check the elements' dropped position store it in cookies. For setting cookies, there are world of code on internet.
Also, you might want to check floating absolute/relative positioning css, if your DOM divs are going to be floating around the page.
GoodLuck.
simplyharsh has the proper answer, but I'd like to expand on it a bit:
The basics of a draggable div aren't too complicated. You attach an onclick handler to initiate the dragging. Internally, that's accomplished by changing the div's CSS so it's position: absolute. Then you start monitoring mouse movements (basically onmousemove) and changing the div's top and left according to the movements you've captured.
Dropping is a bit more complicated. You can always just release the mouse and leave the div wherever you ended up moving it, but that leaves it absolutely positioned and therefore outside of normal document flow. But dropping it "inside" some other element means a lot of prep work.
Because of how mouseover/mouseout/mouseenter events work, they WON'T work while you're dragging an element - you've got your draggable div under the mouse at all times, so there's no mouseenter/leave events being fired on the rest of the page. jquery/mootools and the like work around it letting you specify drop zones. The locations/sizes of these zones are precalculated and as you're dragging. Then, as you're dragging, the dragged object's position is compared to these precalculated drop zone locations for every move event. If you "enter" one of those zones, then internally the libraries fire their mouseenter/mouseleave/mouseover events to simulate an actual mouseenter/leave/over event having occured.
If you drop inside a zone, the div gets attached as a child of that zone. If you drop outside, then it will usually "snap back" to where it was when you initiated the drag.
Resizing is somewhat similar, except you're adjusting height and width instead of top and left.
