我已经尝试了好几天,但我无法让它发挥作用。
我想得到div(ui-widget-content
)的id是可拖动的项目,当我删除并单击div(ui-widget-header
)时,这是被删除的项目,但我无法使其工作。
<script>
$(document).ready(function () {
$("#j1, #j2, #j3, #j4, #j5, #j6").draggable();
$("#p1, #p2, #p3, #p4, #p5, #p6").droppable({
hoverClass: 'ui-state-hover',
helper: 'clone',
cursor: 'move',
drop: function (event, ui) {
$(this).addClass('ui-state-highlight');
$(ui.draggable).addClass('ui-state-highlight');
$(ui.draggable).draggable('enable');
console.log('Dragged: ' + alert(ui.draggable.attr("id")));
}
});
});
$('ui-widget-header').click(function () {
var item_id = ui.item.attr('id');
});
alert('item_id');
//$('.ui-droppable').click(function(){
// var myStringPosition = $('div'); // $(event.target).attr('id');
// $('.ui-droppable').each(function(){
// myStringPosition = $(this)[0].id;
// });
// alert(myStringPosition);
//});
</script>
</head>

<div id="j1" class="ui-widget-content" data-userid="1">Jogador 1</div>
<div id="j2" class="ui-widget-content">Jogador 2</div>

<div id="j4" class="ui-widget-content">Jogador 4</div>
<div id="j5" class="ui-widget-content">Jogador 5</div>
<div id="j6" class="ui-widget-content">Jogador 6</div>

<div id="p2" class="ui-widget-header"><p>Posicao 2</p></div>

<div id="p2" class="ui-widget-header"><p>Posicao 5</p></div>
<div id="p3" class="ui-widget-header"><p>Posicao 6</p></div>

更新3 :看起来没有一种方法可以确定droppable中包含哪个“可拖动”项。您必须有一个方法来记住放入容器的内容。 jquery对象上的data()
函数是一个很好的方法。
在drop函数中:
var itemId = $(ui.draggable).attr("id");
$(this).data('dropped', itemId);
在点击回调中使用:
if ($(item).data('dropped'))
{
alert($(item).data('dropped'));
}
注意:这只会记住最近删除的项目,并且在将其放入新容器后不会将其删除 - 这应该很容易实现。
更新2 :以下内容应提供包含可拖动项目ID的提醒。我把条件放在那里,以确定它是否被移动到底部的容器中。
$('.ui-widget-content').click(function (event) {
var item = event.target;
if (item.offsetTop >= 140)
{
alert(item.id);
}
});

更新:看起来你想要一些与众不同的东西。如果您只想要目标容器的ID,则应该能够使用event.target.id
drop: function (event, ui) {
$(this).addClass('ui-state-highlight');
$(ui.draggable).addClass('ui-state-highlight');
$(ui.draggable).draggable('enable');
var itemId = $(ui.draggable).attr("id");
var destId = event.target.id ;
var message = '"' + itemId + '" was dragged to "' + destId + '"';
alert(message);
console.log(message);
}

原始答案
首先 - 你应该将你的点击处理程序放在document.ready
中。我认为你可能遇到了问题,因为事件目标对象将是被点击的内容,而<p>
元素没有id。如果我理解您的问题,则以下代码可能有效。
$('.ui-widget-header').click(function (event) {
var item = event.target;
if (item.nodeName == 'P') {
item = item.parentNode;
}
alert(item.id);
});

试试这个 您只需将拖动对象ID存储到&#34; dragId&#34;。
