Extjs导出Grid数据到Excel

1、调用方式
var excel = new Ext.Excel({
gridId: 'gridId',--GridId
sheetName: 'sheetName',--sheetName
dsIndex:'oprDate','bizKey','custAbbr','refNo','amount','status','bizItemCn','registerOpAuth','attachCnt','isInCot','remark']--数据源
});
excel.extGridToExcel();--调用方法

2、Export.js
/*
*功能：直接由Ext的grid生成Excel
*注意：只支持IE
*参数：gridId, sheetName
*/
Ext.Excel = function(config){
Ext.apply(this,config);
};

Ext.ExcelNew = function(config){
Ext.apply(this,config);
};

Ext.apply(Ext.Excel.prototype,{
extGridToExcel : function(){

// grid 生成 Excel
var oXL = new ActiveXObject("Excel.Application");
var oWB = oXL.Workbooks.Add();
var oSheet = oWB.ActiveSheet;
var grid = Ext.getCmp(this.gridId);
