首先是在線測試例子: http://vazumihost.vip1.kingidc.net/example/export.htm

實現原理:
ligerui是基於jquery來搭建頁面，一個grid控件本質上是幾個table組合而成
如果可以將這個DOM的架構直接傳回後臺，自然可以輸出爲excel或者word或者pdf
爲何不在前臺Js實現html導出爲excel，因爲js來創建excel這玩意會碰到瀏覽器安全性問題，不實用
這個也貼一個方法，一個js搞定
- function method1() {//整個表格拷貝到EXCEL中
- //檢索瀏覽器
- if(navigator.userAgent.indexOf("MSIE")<0){
- alert('請用ie瀏覽器進行表格導出');
- 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;
- }
- }
- //創建AX對象excel
- var oWB = oXL.Workbooks.Add();
- //獲取workbook對象
- var oSheet = oWB.ActiveSheet;
- //在此進行樣式控制
- oSheet.Rows(1+":"+1).RowHeight =20;//定義行高
- oSheet.Rows(2+":"+2).RowHeight =30;
- oSheet.Rows(1).HorizontalAlignment=3;
- var sel = document.body.createTextRange(); //激活當前sheet
- sel.moveToElementText(curTbl); //把表格中的內容移到TextRange中
- sel.select(); //全選TextRange中內容
- sel.execCommand("Copy"); //複製TextRange中內容
- oSheet.Paste(); //粘貼到活動的EXCEL中
- oXL.Visible = true; //設置excel可見屬性
- oSheet.Application.Quit(); //結束當前進程
- window.opener=null;
- window.close();//關閉當前窗口
- }
下面採用的導EXCEL方法，適合不翻頁的grid，而且無需再讀一次數據庫，
對於翻頁的grid來說，要導全部，當然後臺要再讀一次數據庫，這種導EXCEL方法baidu一大堆，這裏不重複

代碼原理:在點導出按鈕的時候，彈一個print.aspx頁面，這個頁面把grid的html傳給自己一個叫hf的hidden裏面，然後後臺response輸出這個html
