[javascript] CSS /JS to prevent dragging of ghost image?

Is there a way to prevent the user from seeing a ghost of the image they are trying to drag (not concern about security of the images, but the experience).

I've tried this which fixes the problem with the blue selection on text and images but not the ghost image:

img {
  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -o-user-select: none;
  user-select: none;
}

(I also tried nesting the image inside a div with the same rules applied to the div). Thanks

This will disable dragging for an image in all browsers, while preserving other events such as click and hover. Works as long as any of HTML5, JS, or CSS are available.

<img draggable="false" onmousedown="return false" style="user-drag: none" />

If you're confident the user will have JS, you only need to use the JS attribute, etc. For more flexibility, look into ondragstart, onselectstart, and some WebKit tap/touch CSS.

Place the image as a background of an empty div, or under a transparent element. When the user clicks on the image to drag, they are clicking on a div.

<div id="photo-drag-proxy"></div>

You can set the draggable attribute to false in either the markup or JavaScript code.

// As a jQuery method: $('#myImage').attr('draggable', false);_x000D_
document.getElementById('myImage').setAttribute('draggable', false);

<img id="myImage" src="http://placehold.it/150x150">

You can use "Empty Img Element".
Empty Img Element - document.createElement("img")

[HTML Code]
<div id="hello" draggable="true">Drag!!!</div>

[JavaScript Code]
var block = document.querySelector('#hello');
block.addEventListener('dragstart', function(e){
    var img = document.createElement("img");
    e.dataTransfer.setDragImage(img, 0, 0);
})

This work for me, i use some lightbox scripts

.nodragglement {_x000D_
    transform: translate(0px, 0px)!important;_x000D_
}

The be-all-end-all, for no selecting or dragging, with all browser prefixes:

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-o-user-select: none;
-ms-user-select: none;
user-select: none;

-webkit-user-drag: none;
-khtml-user-drag: none;
-moz-user-drag: none;
-o-user-drag: none;
-ms-user-drag: none;
user-drag: none;

You can also set the draggable attribute to false. You can do this with inline HTML: draggable="false", with Javascript: elm.draggable = false, or with jQuery: elm.attr('draggable', false).

You can also handle the onmousedown function to return false. You can do this with inline HTML: onmousedown="return false", with Javascript: elm.onmousedown=()=>return false;, or with jQuery: elm.mousedown(()=>return false)

You can set the image that is shown when an item is dragged. Tested with Chrome.

setDragImage

use

onclick = myFunction();
myFunction(e) {
    e.dataTransfer.setDragImage(someImage, xOffset, yOffset);
}

Alternatively, as already mentioned in the answers, you can set draggable="false" on the HTML element, if not being able to drag the element at all is no issue.

Handle the dragstart event and return false.

Try it:

img {
  pointer-events: none;
}

and try to avoid

* {
  pointer-events: none;
}

You can use a CSS property to disable images in webkit browsers.

img{-webkit-user-drag: none;}

There is a much easier solution here than adding empty event listeners. Just set pointer-events: noneto your image. If you still need it to be clickable, add a container around it which triggers the event.

Very simple don't make it complicated with lots of logic use simple attribute draggable and make it false

<img draggable="false" src="img/magician.jpg" alt="" />

In React all you need is:

  <img
    src={}
    onMouseDown={(e) => {
      e.preventDefault();
      // other code
    }}
  />

For Firefox you need to go a little deeper with this:

var imgs = document.getElementsByTagName('img');

    // loop through fetched images
    for (i = 0; i < imgs.length; i++) {
        // and define onmousedown event handler
        imgs[i].onmousedown = disableDragging;
    }

function disableDragging(e) {
        e.preventDefault();
    }

Enjoy.

You can assign an alternate ghost image if you really need to use drag events and can't set draggable=false. So just assign a blank png like so:

    $('#img').bind({
        dragstart: function(e) {
            var dragIcon = document.createElement('img');
            dragIcon.src = 'blank.png';
            dragIcon.width = 100;
            e.dataTransfer.setDragImage(dragIcon, -10, -10);
        }
    });

Tested on Firefox: removing and putting back the image works! And it's transparent at the execution, too. For instance,

$('.imageContainerClass').mousedown(function() {
    var id = $(this).attr('id');
    $('#'+id).remove();
    $('#'+id).append('Image tag code');
});

EDIT: This works only on IE and on Firefox, strangely. I also added draggable = false on each image. Still a ghost with Chrome and Safari.

EDIT 2: The background-image solution is genuinely the best one. The only subtlety is that the background-size property has to be redefined every time the background-image is changed! Or so, that's what it looked like from my side. Better still, I had an issue with normal img tags under IE, where IE failed to resize the images. Now, the images have the correct dimensions. Simple:

$(id).css( 'background-image', url('blah.png') );
$(id).css( 'background-size', '40px');

Also, perhaps consider those:

background-Repeat:no-repeat;
background-Position: center center;

I found that for IE, you must add the draggable="false" attribute to images and anchors to prevent dragging. the CSS options work for all other browsers. I did this in jQuery:

$("a").attr('draggable', false); 
$("img").attr('draggable', false);

<img src="myimage.jpg" ondragstart="return false;" />

I think you can change your

img {
  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -o-user-select: none;
  user-select: none;
}

into a

img {
  -webkit-user-drag: none;
  -khtml-user-drag: none;
  -moz-user-drag: none;
  -o-user-drag: none;
  user-drag: none;
}
