1、在线预览Excel文件
(1) 运行环境
① 浏览器：支持IE7-IE11（平台版本还支持Chrome和Firefox）
② IE工具栏-Internet 选项：将www.ntko.com加入到浏览器的可信站点中，不启用保护模式，并将HTTPS验证取消
③ 如果是开发人员首次使用文档控件，需要将控件手动注册控件，获取控件的版本clisid以及版本信息Version（如果程序已经开发完则可以忽略此步骤）
(2) 创建一个加载控件的JS文件，用户只需修改控件版本号Version，classid，cab包路径，以及添加授权即可。具体可访问http://dev.ntko.com:8000/查看
① JS文件代码如下：（-1表示TRUE,0表示FALSE）
////----在线编辑Excel并保存
document.write('<object id="TANGER_OCX" classid="clsid:A64E3073-2016-4baf-A89D-FFE1FAA10EC0"');
document.write('codebase="NTKO/OfficeControl.cab#version=5,0,3,0" width="100%" height="100%"> ');
document.write('<param name="Toolbars" value="-1"> '); // 工具栏
document.write('<param name="Menubar" value="0"> '); //菜单栏
document.write('<param name="CustomToolBar" value="-1"> ');
document.write('<param name="Titlebar" value="-1"> '); //标题栏
document.write('<param name="Caption" value="华测计量技术有限公司专用">');//标题内容
document.write('<param name="IsUseControlAgent" value="-1"> '); //是否是控制请求数据，其他请他不允许
document.write('<param name="IsNoCopy" value="0"> '); //0不允许复制
document.write('<param name="IsDirectConnect" value="-1"> ');
document.write('<param name="DefaultOpenDocType" value="1"> ');//1表示只能打开word文档
document.write('<param name="FileOpen" value="0"> ');
document.write('<param name="FileNew" value="0"> ');
document.write('<param name="FileSave" value="0"> ');
document.write('<param name="FileSaveAs" value="0"> ');
document.write('<param name="FilePrint" value="0"> ');
document.write('<param name="FilePrintPreview" value="0"> ');
document.write('<param name="ProductCaption" value="Office Anywhere 3.0"> ');
document.write('<param name="ProductKey" value="65F867689D7FF5CD02FBE4AA23764306F715A9E2">');
document.write('<SPAN STYLE="color:red">不能装载NTKO OFFICE文档控件。请在检查浏览器的选项中检查浏览器的安全设置。</SPAN> ');
document.write('</object> ');
