js实现ext grid导出到excel
将grid作为参数传入以下函数即可:
function outputAddress(grid){ try { var xls = new ActiveXObject("Excel.Application"); } catch (e) { alert("要打印该表，您必须安装Excel电子表格软件，同时浏览器须使用“ActiveX 控件”，您的浏览器须允许执行控件。 请点击【帮助】了解浏览器设置方法！"); //return ""; } xls.visible = true; //设置excel为可见 var xlBook = xls.Workbooks.Add; var xlSheet = xlBook.Worksheets(1); var cm = grid.getColumnModel(); var colCount = cm.getColumnCount(); var temp_obj = []; //只下载没有隐藏的列(isHidden()为true表示隐藏,其他都为显示) //临时数组,存放所有当前显示列的下标 for (i = 1; i < colCount; i++) { if (cm.isHidden(i) == true) { } else { temp_obj.push(i); } } for (i = 1; i <= temp_obj.length - 2; i++) { //显示列的列标题 xlSheet.Cells(1, i).Value = cm.getColumnHeader(temp_obj[i - 1]); } var store = grid.getStore(); var recordCount = store.getCount(); var view = grid.getView(); for (i = 1; i <= recordCount; i++) { for (j = 1; j <= temp_obj.length; j++) { //EXCEL数据从第二行开始,故row = i + 1; xlSheet.Cells(i + 1, j).Value = view.getCell(i - 1, temp_obj[j - 1]).innerText; } } xlSheet.Columns.AutoFit; xls.ActiveWindow.Zoom = 75 xls.UserControl = true; //很重要,不能省略,不然会出问题 意思是excel交由用户控制 xls = null; xlBook = null; xlSheet = null;}?
