我知道我遗漏了一些非常基本的东西,但是在您将“可放置” DIV 堆叠在一起的情况下使用 jQuery 时(想想嵌套框),您如何允许和接受最顶部 DIV 上的元素放置然后取消拖放事件,这样它就不会被发送到下面的其他“可拖放”DIV?
$('#'+objectID+" .task-droppable").droppable({
accept: function(d) {
if(d.hasClass("source-task")||d.hasClass("source-sequence")){ //sequences can contain both sequences and tasks
return true;
} //end if
}, //end accept
activeClass: "isDropDest",
//hoverClass: "isDragging",
//this is used for both drag/drop and item moves
drop: function(event, ui) {
var draggableId = ui.draggable.attr("id");
var droppableId = $(this).attr("id");
//var sender_id = ui.sender.attr('id');
//var receiver_id = $(this).attr('id');
//var item_id = ui.item.attr('id');
//var above_id = ui.item.prev().attr('id');
//var below_id = ui.item.next().attr('id');
//check if this is a drag/drop or a move by looking for the object class
if(!$('#'+draggableId).hasClass('object')) {
$('#'+draggableId).css('top', '0px');
$('#'+draggableId).css('left', '0px');
createObject(draggableId, droppableId);
} else {
//handle the move - do nothing
} //end if
event.stopPropagation();
} //end drop
}); //end droppable
抱歉,今天的咖啡不够。
