jQuery draggable - 将小图像拖入父级
jQuery draggable - Drag small image inside parent
我有一个图像(小圆圈),我想将其拖到另一个更大的图像(轴)之上。如何将较大的图像设置为包含圆圈的父图像?
下面是我试过的,但是圆不能拖到整个大图上面,只能垂直拖。
代码:
$(function() {
$("#draggable").draggable({
containment: "#container",
scroll: false
});
});
#draggable {
position: relative;
left: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.2/jquery-ui.min.js"></script>

从 #draggable
中删除 position: relative;
。
以下是我对您的代码所做的一些更改:
