项目一个功能需要将table中的数据导出成一个Excel文件。在百度搜索上，大多是用ActiveX去做，可这个只能在ie浏览器上用，而且还要更改浏览器设置，这个方法明显不好用。

我经过多次搜索和研究，千辛万苦，终于找到一个方法，能兼容所有浏览器。代码如下：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>EB页面导出为EXCEL文档的方法</title>
<script>  
//打印pdf文件
 function myprint(){
 var global_Html = document.body.innerHTML;       

      document.body.innerHTML = document.getElementById('tableExcel').innerHTML;         　　　　　　　　　　　　　　     
       window.print();

        window.setTimeout(function () {

            document.body.innerHTML = global_Html;       

}, 1500); 
}
</script>
<script type="text/javascript" language="javascript">
        var idTmr;
        function  getExplorer() {
            var explorer = window.navigator.userAgent ;
            //ie
            if (explorer.indexOf("MSIE") >= 0) {
                return 'ie';
            }
            //firefox
            else if (explorer.indexOf("Firefox") >= 0) {
                return 'Firefox';
            }
            //Chrome
            else if(explorer.indexOf("Chrome") >= 0){
                return 'Chrome';
            }
            //Opera
            else if(explorer.indexOf("Opera") >= 0){
                return 'Opera';
            }
            //Safari
            else if(explorer.indexOf("Safari") >= 0){
                return 'Safari';
            }
        }
        function method1(tableid) {//整个表格拷贝到EXCEL中
            if(getExplorer()=='ie')
            {
                var curTbl = document.getElementById(tableid);
                var oXL = new ActiveXObject("Excel.Application");
                 
                //创建AX对象excel
                var oWB = oXL.Workbooks.Add();
                //获取workbook对象
                var xlsheet = oWB.Worksheets(1);
                //激活当前sheet
                var sel = document.body.createTextRange();
                sel.moveToElementText(curTbl);
                //把表格中的内容移到TextRange中
                sel.select();
                //全选TextRange中内容
                sel.execCommand("Copy");
                //复制TextRange中内容 
                xlsheet.Paste();
                //粘贴到活动的EXCEL中      
                oXL.Visible = true;
                //设置excel可见属性
 
                try {
                    var fname = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
                } catch (e) {
                    print("Nested catch caught " + e);
                } finally {
                    oWB.SaveAs(fname);
 
                    oWB.Close(savechanges = false);
                    //xls.visible = false;
                    oXL.Quit();
                    oXL = null;
                    //结束excel进程，退出完成
                    //window.setInterval("Cleanup();",1);
                    idTmr = window.setInterval("Cleanup();", 1);
 
                }
            }
            else
            {
                tableToExcel(tableid)
            }
        }
        function Cleanup() {
            window.clearInterval(idTmr);
            CollectGarbage();
        }
        var tableToExcel = (function() {
              var uri = 'data:application/vnd.ms-excel;base64,',
              template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>',
                base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) },
                format = function(s, c) {
                    return s.replace(/{(\w+)}/g,
                    function(m, p) { return c[p]; }) }
                return function(table, name) {
