如果我有更多元素,我如何跟踪拖放事件,例如我有4个div
<div data-val="val-1">Menu 1</div>
<div data-val="val-2">Menu 2</div>
<div data-val="val-3">Menu 3</div>
<div data-val="val-4">Menu 4</div>
我有8个列表项
<ul>
<li id="something-1">Something 1</li>
<li id="something-2">Something 2</li>
<li id="something-3">Something 3</li>
<li id="something-4">Something 4</li>
<li id="something-5">Something 5</li>
<li id="something-6">Something 6</li>
<li id="something-7">Something 7</li>
<li id="something-8">Something 8</li>
</ul>
如果我将ID为li
的{{1}}拖到包含something-3
的div中,如何将其发布到应发布两个值的文件中。

$(function() {
$( "ul" ).sortable({
connectWith: ".connected",
receive: function(event, elem) {
var menu = $(this).data('val');
var item = $(elem.item[0]).attr('id');
$.post('yourphp.php', { item: item, menu: menu }, function () {
console.log('Menu configuration saved !');
});
}
}).disableSelection();
});
