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;}
