Dev*_*man 2 jquery jquery-ui jquery-ui-draggable jquery-ui-droppable
我基于示例购物车演示实现了 jQuery 的可拖放功能。当您将其拖出可放置对象时,我希望能够将其<li>从可放置对象中删除。我认为这可能与droppable out 事件有关,但 ui 参数为空。有谁知道解决方案吗?
这是一个完整的工作解决方案,尚未完全测试,您仍然应该对其进行调试:{重新分配可拖动到已放置的元素以触发退出事件} {您也应该重新分配可放置!}
$(function () {
$("#catalog").accordion();
$("#catalog li").draggable({
appendTo: "body",
helper: "clone"
});
$("#cart ol").droppable({
out: function (event, ui) {
var self = ui;
ui.helper.off('mouseup').on('mouseup', function () {
$(this).remove();
self.draggable.remove();
});
},
activeClass: "ui-state-default",
hoverClass: "ui-state-hover",
accept: ":not(.ui-sortable-helper)",
drop: function (event, ui) {
if (ui.draggable.is('.dropped')) return false;
$(this).find(".placeholder").remove();
$("<li></li>").text(ui.draggable.text()).appendTo(this).draggable({
appendTo: "body",
helper: "clone"
}).addClass('dropped');
}
}).sortable({
items: "li:not(.placeholder)",
sort: function () {
// gets added unintentionally by droppable interacting with sortable
// using connectWithSortable fixes this, but doesn't allow you to customize active/hoverClass options
$(this).removeClass("ui-state-default");
}
});
});
