当前输出
预期输出
正如我们在第一张图片中所看到的，可拖动的ul li在可放置区域的右侧。
当我从数据库中获取内容时，可拖动的ul中将包含n个元素。
但是，当我尝试将height : 800px和overflow-x : scroll放入可拖动的ul时，我看不到已经放置在可放置区域上的元素。
供引用，这是代码

最佳答案
解决了..
只是几个CSS hacks并完成了..;)
第一个变化:
.arialView {
background-color: #999999;
background-image: url("Chrysanthemum.jpg");
background-position: center center;
background-repeat: no-repeat;
float: left;
height: 800px;
**position: absolute;**
width: 1200px;
}
第二个变化:
.arialViewOptions {
border-left: 1px solid #000000;
float: left;
height: 800px;
list-style: none outside none;
margin: 0;
overflow: auto;
padding: 0 0 0 1200px;
position: relative;
width: 100px;
}
第三个变化:在js中
storedData = $.parseJSON(storedData);
$.each(storedData, function(key, value) {
$("#" + key).css({top : value.top, left : value.left}).css("position", "fixed");
$(".arialViewOptions").append("<li rel='" + key + "'>" + $("#" + key).html() + "</li>");
$(".arialViewOptions li[rel=" + key + "]").css({top : value.top, left : value.left}).css("position", "fixed").addClass("needToAnimate");
});
