Question

当前输出

current output

预期输出 expected output

正如我们在第一张图片中看到的那样，可拖动的ul li位于可放置区域的右侧。

当我从数据库中获取内容时，我将在可拖动的ul中拥有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，我无法看到已放置在可放置区域的元素。< / p>

供参考，这是代码

Answer 1

解决..

只是几个css hacks并完成了它...;）

首先改变：

.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;
}

第二次改变：

.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;
}

第三次改变：在js

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");
                });
