实现原理:
ligerui是基于jquery来搭建页面，一个grid控件本质上是几个table组合而成
如果可以将这个DOM的架构直接传回后台，自然可以输出为excel或者word或者pdf
为何不在前台Js实现html导出为excel，因为js来创建excel这玩意会碰到浏览器安全性问题，不实用
这个也贴一个方法，一个js搞定
function method1() {//整个表格拷贝到EXCEL中 //检索浏览器 if(navigator.userAgent.indexOf("MSIE")<0){ alert('请用ie浏览器进行表格导出'); return ; } var tableid="maingrid"; var curTbl = document.getElementById(tableid); var oXL = null; try { oXL = GetObject("", "Excel.Application"); } catch (E) { try { oXL = new ActiveXObject("Excel.Application"); } catch (E2) { alert("Please confirm:\n1.Microsoft Excel has been installed.\n2.Internet Options=>Security=>Setting \"Enable unsafe ActiveX\""); return; } } //创建AX对象excel var oWB = oXL.Workbooks.Add(); //获取workbook对象 var oSheet = oWB.ActiveSheet; //在此进行样式控制 oSheet.Rows(1+":"+1).RowHeight =20;//定义行高 oSheet.Rows(2+":"+2).RowHeight =30; oSheet.Rows(1).HorizontalAlignment=3; var sel = document.body.createTextRange(); //激活当前sheet sel.moveToElementText(curTbl); //把表格中的内容移到TextRange中 sel.select(); //全选TextRange中内容 sel.execCommand("Copy"); //复制TextRange中内容 oSheet.Paste(); //粘贴到活动的EXCEL中 oXL.Visible = true; //设置excel可见属性 oSheet.Application.Quit(); //结束当前进程 window.opener=null; window.close();//关闭当前窗口 } (这个方法，只可IE并且要允许不安全的activex运行，这也太危险了，这年头...)下面采用的导EXCEL方法，适合不翻页的grid，而且无需再读一次数据库，
对于翻页的grid来说，要导全部，当然后台要再读一次数据库，这种导EXCEL方法baidu一大堆，这里不重复
