但丁少爷

<div id="win1" class="mini-window" title="待办信息" style="width:400px;height:250px;"
    showMaxButton="true" showCollapseButton="true" showShadow="true" showCloseButton="false"
    showToolbar="true" showFooter="true" showModal="false" allowResize="true" allowDrag="true" onbuttonclick="onButtonClick"
    >
    <div id="datagrid1" class="mini-datagrid" style="width:100%;height:100%; font-style: "
            url="/TBPWeb/informRemindAction.do?method=findRemindMsg"  idField="INFORMID" allowResize="false" showPager="false" showColumns="false" allowCellWrap="true"
            sizeList="[20,30,50,100]" pageSize="20" ajaxOptions="{contentType:'application/x-www-form-urlencoded; charset=utf-8'}">
            <div property="columns">
                <div field="DBMSG" align="left" headerAlign="center" allowSort="true">待办信息</div>
                <div field="URL" align="center" headerAlign="center" allowSort="true" visible='false'>链接地址</div>
                <div name="action" width="20%" headerAlign="center" align="center" renderer="onActionRendererEdit" cellStyle="padding:0;">处理</div>
            </div>
        </div>
</div>

我想用js控制页面打开或者折叠

dforce

mini.get("win1").setExpanded(false/true);
