I searched a lot to find a tutorial for drag & drop with jQuery alone (without UI), but due to the popularity of JQuery UI, all drag and drop features are based on JQuer
There are several plugins that you may use take a look at the following
http://wayfarerweb.com/jquery/plugins/animadrag/
http://threedubmedia.com/code/event/drag/demo/
it still jquery but no UI
I found this one very useful: http://draggabilly.desandro.com/
http://thezillion.wordpress.com/2012/09/27/javascript-draggable-2-no-jquery
See this. It's core JS and easy to implement.
Came across the same problem, and 33.4 kilobytes for the minified jqueryUI with only draggable and droppable is too large for the limited functionality I needed. The approach below isn't working code - it's just a simple structure to visualize what needs to happen.
$('.draggable').on{
mousemove : function(){
var mouseposition = { // this also needs to account for onclick offset of pointer vis-a-vis element
x : pageX,
y : pageY
};
$(this).css({
top : mouseposition.y,
left : mouseposition.y
});
if( // this statement is kinda bogus, idea is to perform a collision detection via coordinate comparison
$('.draggable').offset().top < $(.droppable').offset().top
&&
$('.draggable').offset().left < $(.droppable').offset().left
) {
alert('the item has been dropped');
}
}
});
I understand this is an old post, but i was also interested in doing this without Jquery UI. I checked the links above, but i found this to be the best. It's only 8kb minified (UI sortable ~30, i've read), and is independent of any mammoth JQuery library (although those CAN make our lives easier sometimes).
