这是我的剧本:
<script>
$(function() {
t1 = window.performance.now()
var $sortable1 = $( "#dragableElement" ).sortable({
connectWith: ".connectedSortable",
items: ".sorting-initialize",
containment: "window"
});
$sortable1.find(".ui-state-default").one("mouseenter",function(){
$(this).addClass("sorting-initialize");
$sortable1.sortable('refresh');
});
t2 = window.performance.now()
console.log(t2-t1)
});
</script>
是否可以在此脚本中更改拖动项目的样式?例如添加背景:&#39;黄色&#39;它改变颜色等?

您还可以使用jQueryUi可排序事件start进行此尝试: -
$( "#dragableElement" ).sortable({
connectWith: ".connectedSortable",
items: ".sorting-initialize",
containment: "window",
start: function( event, ui ) {
$(ui.item).addClass("yellow");
},
stop:function( event, ui ) {
$(ui.item).removeClass("yellow");
}
});

对项目进行排序时,会将一个类ui-sortable-helper
添加到该项目中。您可以使用此类来更改正在排序的项目的外观。然后,您可以使用CSS规则来更改此项目的外观。但是,您必须确保您的css覆盖jQuery UI的默认css。为此,您可能需要非常具体的选择器。
演示:http://jsfiddle.net/UAcC7/1503/
CSS:
.ui-sortable-helper {
background:green;
}
HTML:
<div class="demo">
<ul id="sortable">
<li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 1</li>
<li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 2</li>
<li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 7</li>
</ul>
</div>
<!-- End demo -->
<div class="demo-description" style="display: none; ">
<p>Enable a group of DOM elements to be sortable. Click on and drag an element to a new spot within the list, and the other items will adjust to fit. By default, sortable items share <code>draggable</code> properties.</p>
</div>
<!-- End demo-description -->
JS:
$("#sortable").sortable();
