Drag and drop in Opera/Safari

Ta for new comments. Will check those.

Slug army eh? One never lives some things down on CUK.

New browsers support quite complex drag and drop stuff (which is defined in the HTML 5 spec) which you can extend and override in various wonderful ways.

Try setting the draggable attribute on the relevant images to false:

<img src="slug_army.jpg" draggable="false" />

and it should disable it.

It's handy if you want to grab an image from a website: rather than mucking about with menus and so on, you can just grab the image and drag it onto the desktop.

Xog.

You do a lot of cross browser JavaScript. Are you using a framework such as JQuery or Prototype? Makes life a LOT easier.

Can't believe people are hand coding drag n drop these days.

I do a lot of cross browser JS/DOM/AJAX work and use jQuery extensively. Makes it a piece of cake.

Hey, it all works in Google Chrome!

Chrome opens pages in a flash too, unlike the others.

Pleasure.

Cheers OH! Bunged that handler that on a couple of images and it seems to work, no ghosty drag things in FF, opera or Safari.

Ps Oh no! Google has come out with another browser!

[OrangeHopper]

Might this help.

Dragging your avatar around is just too scary!

Quite why I have no idea but these browsers have an odd habit of implementing dragging by default. On a page with no jscript in it you can click on an image and a version of the image with a "no go sign" on it can be dragged around. On large background images a bit of it gets dragged.

In an interactive it is confusing that inactive pictures are draggable. The bigger problem is that it interferes with wanted drag n drop in jscript. My code works ok if I click and leave the mouse in position for a second before I start moving. Too quick and I am moving this pointless ghost image around while the image I want to drag moves a little bit and the clicks gets all out of sync.

Firefox has this ghosty thing too but it seems much faster and causes no drag n drop problems. Sensible IE (hooooray!) does not do it all.

Any way of turning this behaviour off? Cheers.


PS I have found somw D&D code that works (beats me what there is in it that is significantly diff from what I am using) but would still like to turn this behaviour off altogether if possible,
