我使用Rubaxa sortable使列表项可排序。现在我想更改被拖动列表的背景颜色。 现在我使用文档中提供的ghost类,但是只有文本背景是彩色的,但我希望整个列表和编号都有背景颜色。 任何人都可以知道我如何通过javascript添加自定义类到sortable,以便我可以实现相同。
Sortable.create(simpleList, {
ghostClass: "ghost"
});

.ghost {
color: #fff;
background-color: #c00;
}
.container {
text-align: center;
}
ol {
display: inline-block;
}

<div class="container">
<ol id="simpleList" class="list-group">
<li>A Good Meal</li>
<li>A technical Improvement</li>
<li>Nonsense</li>
</ol>
</div>

最后,我做到了。请检查this。我对您的html
,css
和Jquery
进行了一些更改。
HTML
<div class="container">
<ol id="simpleList" class="list-group">
<li><span class="index">1.</span>A Good Meal</li>
<li><span class="index">2.</span>A technical Improvement</li>
<li><span class="index">3.</span>Nonsense</li>
</ol>
</div>
CSS
.ghost {
color: #fff;
background-color: #c00;
position: relative;
}
.index {
display: inline-block;
height: 100%;
width: 10px;
margin-right: 10px;
background: inherit;
color: inherit;
}
.container {
text-align: center;
}
ol {
display: inline-block;
list-style:none;
text-align: left;
}
Jquery的
Sortable.create(simpleList, {
ghostClass: "ghost",
onEnd: function ( /**Event*/ evt) {
$('.list-group li').each(function (index) {
var newIndex = index + 1 + '.';
$(this).find('.index').html(newIndex);
});
}
});
