这是我写的一个js导出EfsFrame框架excel方法 只需要传入grid的id即可

JScript code

function doOut(gridid) {        var gView = Efs.getExt(gridid).getView();         var rows = gView.getRows().length; //行数        var columncount = Efs.getExt(gridid).getColumnModel().getColumnCount(); //列数        var r = 1;        if (gView.getHeaderCell(1).innerText == " ") {            r = 2;        }        try        {        var oXL = new ActiveXObject("Excel.Application");        //创建AX对象excel         var oWB = oXL.Workbooks.Add();        //获取workbook对象         var oSheet = oWB.ActiveSheet;        //激活当前sheet        catch(e){             alert("创建excel对象失败，请确认已经安装了excel软件!");             return false;         }         var i = r;        for (var j= 1; i < columncount; j++,i++) {            oSheet.Cells(1, j).value = gView.getHeaderCell(i).innerText;        }        for (var k = 0, l = 2; k < rows; k++, l++) {            i = r;            for (var x = 1; i < columncount; x++, i++) {                var y = gView.getCell(k, i).firstChild.innerHTML;                if (y == null || y == "&nbsp;") {                    y = "";                }                oSheet.Cells(l, x).value = "'"+y;            }        }        oXL.Visible = true;        oXL.Quit();        oXL = null;    }
