前端

访问文件编辑的那个页面：
<script src="${rootpath}/jquery.min.js"></script>
<script src="${rootpath}/pageoffice.js" id="po_js_main"></script>
<a href="javascript:POBrowser.openWindowModeless('${rootpath}/broker/document/documentEdit?id=${item.id}', 'fullscreen=yes;')">在线编辑</a>

documentEdit
<div style="width:100%; height:100%;">
  ${pageOffice}
</div>
<script type="text/javascript">
    function Save() {
        document.getElementById("PageOfficeCtrl1").WebSave();
        // if (document.getElementById("PageOfficeCtrl1").CustomSaveResult == "ok") {
        //     document.getElementById("PageOfficeCtrl1").Alert('保存成功！');
        // }
        document.getElementById("PageOfficeCtrl1").Alert('保存成功！');
    }
</script>
