同样的两个mui的界面 ID为dayShare的可以上下滑动；ID为weekShare却不能上下滑动，是什么原因

Question

<div id="dayShare" class="mui-slider-item mui-control-content mui-active">
    <div id="scroll_view" class="mui-scroll-wrapper" style="top:44px">
        <div class="mui-scroll">
            <div id="emptyDiv" class="reportLineDiv" style="display: none;">暂无数据</div>
            <div class="lineDiv">
                <div id="forward_title" class="titleDiv"></div>
                <div id="line_day_share_forward" class="reportLineDiv"></div>
            </div>
            <div class="lineDiv">
                <div id="read_title" class="titleDiv"></div>
                <div id="line_day_share_read" class="reportLineDiv"></div>
            </div>
            <div class="lineDiv">
                <div id="postRead_title" class="titleDiv"></div>
                <div id="line_day_share_postRead" class="reportLineDiv"></div>
            </div>
            <div class="lineDiv">
                <div id="download_title" class="titleDiv"></div>
                <div id="line_day_click_download" class="reportLineDiv"></div>
            </div>
        </div>
    </div>
</div>

ID为dayShare的可以上下滑动；ID为weekShare却不能上下滑动

<div id="weekShare" class="mui-slider-item mui-control-content">
    <div id="scroll_view" class="mui-scroll-wrapper" style="top:44px;">
        <div id="mui-scroll">
            <div id="emptyDiv" class="reportLineDiv" style="display: none;">暂无数据</div>
            <div class="lineDiv">
                <div id="w_forward_title" class="titleDiv"></div>
                <div id="line_week_share_forward" class="reportLineDiv"></div>
            </div>
            <div class="lineDiv">
                <div id="w_read_title" class="titleDiv"></div>
                <div id="line_week_share_read" class="reportLineDiv"></div>
            </div>
            <div class="lineDiv">
                <div id="w_postRead_title" class="titleDiv"></div>
                <div id="line_week_share_postRead" class="reportLineDiv"></div>
            </div>
            <div class="lineDiv">
                <div id="w_download_title" class="titleDiv"></div>
                <div id="line_week_click_download" class="reportLineDiv"></div>
            </div>
        </div>
    </div>
</div>

这两个DIV是同一个页面，效果如图所示，只有日分享可以上下滑动，周分享与月分享都不能上下滑动：

<script type="text/javascript">
    mui.init();
    mui('.mui-scroll-wrapper').scroll();
</script>

抱大腿啦，请问这是什么原因？

Answer 1

找到原因了：mui-scroll应该是class，而非ID。
错误原因是，我的周分享与月分享都是这样写的：<div id="mui-scroll">
改正代码：<div class="mui-scroll">
