jQuery UI可拖动属性

Question

我有一个清单:

<ul id="selector">
   <li id="1">One</li>
   <li id="2">Two</li>
</ul>

然后我有:

$("#selector li").draggable({
revert: "valid"
});
$("#xyz tr").droppable({
drop: function(event, ui) {
console.log(ui.draggable.text());
}
});

问:如何确定丢弃了id = 1或id = 2？text属性给我"One"或"Two",但我需要"1"或"2".

Answer 1

使用此方法:

ui.draggable.attr('id')
