当拖动可拖动元素并将其放置在可放置区域时,我希望向可拖动元素添加一个新类,以便可以使用CSS更改其样式。这是我目前的情况:
<aside>
<div>1</div>
<div>2</div>
<div>3</div>
</aside>
<section></section>
$(document).ready(function(){
//Test
$("aside div").draggable({
revert: "invalid",
containment: "document",
helper: "clone",
cursor: "move"
});
$('section').droppable({
accept: "aside div",
activeClass: "ui-state-highlight",
drop: function( event, ui ) {
//valami
alert('lol');
}
});
});
aside {
float:left;
width:200px;
}
aside div {
width:200px;
height:100px;
background:red;
margin:0 0 10px 0;
}
section {
float:right;
width:400px;
height:320px;
background:green;
}
