Question

Can anyone tell me how I can write a function in accept condition and then how does it finds out that what to accept and what not to accept. For example, I want to accept div a and div b in accept condition. How can I write I through a function?

Answer 1

If you want the droppable to accept a selection of elements you can do something like this:

$(".droppable").droppable({
    accept: function(d) { 
        if(d.hasClass("foo")||(d.attr("id")=="bar")){ 
            return true;
        }
    }
});

This droppable will accept elements with the class "foo" or an element with the id "bar"
