使用PageOffice实现文档（word,excel,pdf）在线预览编辑[通俗易懂]

最近发现一款不错的插件的PageOffice,地址是：http://www.zhuozhengsoft.com/Technical/  他可以实现word,excel、pdf在线预览以及在线编辑。虽然商用的话需要收费，但是有免费的试用版，在实现自己毕业设计或是做样品的时候 是一个不错的选择。他同时支持java\c#\php.一旦有了正真的项目花钱再买也可以。同时自己也可以熟悉如何使用。接着下面实现在线预览。

		poCtrl1.setServerPage(request.getContextPath() + "/poserver.zz"); // 此行必须
		poCtrl1.setTitlebar(false); // 隐藏标题栏(pageoffice的标题)
		poCtrl1.setMenubar(false); // 隐藏菜单栏（文件一个设置）
		poCtrl1.setOfficeToolbars(false);// 隐藏Office工具条（word 的编辑按钮）
		// poCtrl1.setCustomToolbar(false);// 隐藏自定义工具栏（保存 关闭 全屏）
		poCtrl1.addCustomToolButton("打印", "ShowPrintDlg()", 6);
		poCtrl1.addCustomToolButton("全屏切换", "SwitchFullScreen()", 4);
