java

如今各大浏览器基本都支持data协议，因此咱们可使用该协议去将网页中的table转化为excel下载下来node

对html 进行base64编码处理
编码后的html内容增长前缀 data:application/vnd.ms-excel; ，便可使浏览器将其中的数据当作excel来处理，浏览器将提示下载或打开excel文件
代码小例：

<html> <head> <meta http-equiv="content-Type" content="text/html;charset=utf-8"/> <script type="text/javascript"> function base64 (content) { return window.btoa(unescape(encodeURIComponent(content))); } function exportOffice(tableID){ var type = 'doc'; var table = document.getElementById(tableID); var excelContent = table.innerHTML; var excelFile = "<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:x='urn:schemas-microsoft-com:office:"+type+"' xmlns='http://www.w3.org/TR/REC-html40'>"; excelFile += "<head>"; excelFile += "<!--[if gte mso 9]>"; excelFile += "<xml>"; excelFile += "<x:ExcelWorkbook>"; excelFile += "<x:ExcelWorksheets>"; excelFile += "<x:ExcelWorksheet>"; excelFile += "<x:Name>"; excelFile += "{worksheet}"; excelFile += "</x:Name>"; excelFile += "<x:WorksheetOptions>"; excelFile += "<x:DisplayGridlines/>"; excelFile += "</x:WorksheetOptions>"; excelFile += "</x:ExcelWorksheet>"; excelFile += "</x:ExcelWorksheets>"; excelFile += "</x:ExcelWorkbook>"; excelFile += "</xml>"; excelFile += "<![endif]-->"; excelFile += "</head>"; excelFile += "<body>"; excelFile += excelContent; excelFile += "</body>"; excelFile += "</html>"; var base64data = "base64," + base64(excelFile); switch(type){ case 'excel': window.open('data:application/vnd.ms-'+type+';'+base64data); break; case 'powerpoint': window.open('data:application/vnd.ms-'+type+';'+base64data); break; } } </script> </head> <body> <table id="targetTable"> <tr align="center"> <th>名次</th> <th>姓名</th> <th>成绩</th> </tr> <tr align="center"> <td>1</td> <td>小明</td> <td>100</td> </tr> <tr align="center"> <td>2</td> <td>小红</td> <td>95.5</td> </tr> </table> </br> <input id="Button1" type="button" value="导出" onclick="exportOffice('targetTable')" /> </body> </html>

今天上来发现，好多人，会遇到文件名，格式等问题。这里添加一种方法。兼容性我没有测试，你们能够试下，不过须要利用JQ直接贴代码了。jquery 引入文件在http://download.csdn.net/download/aa122273328/10103711 注意必定要引jquery-3.2.1.min.js，jquery.table2excel.js对应的文件。jquery-3.2.1.min.js这个看你对应的文件版本，不重要。若有问题，欢迎批评指导。

有时候咱们须要把网页中的数据导出excel格式来，那么咱们用下面两种方法能够完成。jquery

第一种.自写代码

<html> <head> <meta http-equiv="content-Type" content="text/html;charset=utf-8"/> <script type="text/javascript"> function base64 (content) { return window.btoa(unescape(encodeURIComponent(content))); } /* *@tableId: table的Id *@fileName: 要生成excel文件的名字（不包括后缀，可随意填写） */ function tableToExcel(tableID,fileName){ var table = document.getElementById(tableID); var excelContent = table.innerHTML; var excelFile = "<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'>"; excelFile += "<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>"; excelFile += "<body><table>"; excelFile += excelContent; excelFile += "</table></body>"; excelFile += "</html>"; var link = "data:application/vnd.ms-excel;base64," + base64(excelFile); var a = document.createElement("a"); a.download = fileName+".xlsx"; a.href = link; a.click(); } </script> </head> <body> <button type="button" onclick="tableToExcel('item','data')">导出</button> <table id="item"> <tr> <th>编号</th> <th>姓名</th> <th>年龄</th> </tr> <tr> <td>1</td> <td>小明</td> <td>19</td> </tr> <tr> <td>2</td> <td>小芳</td> <td>20</td> </tr> <tr> <td>3</td> <td>大军</td> <td>22</td> </tr> </table> </body> </html>

**git

第二种.jquery插件

**
首先要先下载一个jquery.table2excel.js插件(网上搜搜)，而后使用。github

<!doctype html> <html lang="zh"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>table2excel</title> <link rel="stylesheet" href="http://libs.baidu.com/bootstrap/3.2.0/css/bootstrap.min.css"> </head> <body> <header class="jq22-header"> <h4>table2excel-可将HTML表格内容导出到Excel中的jQuery插件 <span>jQuery Plugin to export HTML tabled to Excel Spreadsheet Compatible Files</span></h4> </header> <section class="jq22-container"> <div class="container" style="padding:30px 0"> <div class="row"> <div class="md-col-8"> <div class="table-responsive table2excel" data-tableName="Test Table 1"> <table class="table table-striped table-bordered table-hover"> <thead> <tr class="noExl"> <td class="danger">带<code>noExl</code>class的行不会被输出到excel中</td> <td class="danger">带<code>noExl</code>class的行不会被输出到excel中</td> </tr> <tr> <td class="success">这一行会被导出到excel中</td> <td class="success">这一行会被导出到excel中</td> </tr> </thead> <tbody> <tr> <td>单元格1-1</td> <td>单元格1-2</td> </tr> <tr> <td>单元格2-1</td> <td>单元格2-2</td> </tr> <tr> <td>单元格3-1</td> <td>单元格3-2</td> </tr> </tbody> <tfoot> <tr> <td colspan="2" class="warning">合并2个单元格</td> </tr> </tfoot> </table> </div> </div> </div> <button id="btn" class="btn btn-primary">点击这里将表格内容导出到excel中</button> </div> </section> <script src="http://www.jq22.com/jquery/1.11.1/jquery.min.js"></script> <script>window.jQuery || document.write('<script src="js/jquery-1.11.0.min.js"><\/script>')</script> <script src="dist/jquery.table2excel.js"></script> <script> $(function() { $("#btn").click(function(){ $(".table2excel").table2excel({ exclude: ".noExl", name: "Excel Document Name", filename: "myFileName", exclude_img: true, exclude_links: true, exclude_inputs: true }); }); }); </script> </body> </html>

https://blog.csdn.net/jesslu/article/details/77866040

jquery-table2excel是一款能够将HTML表格的内容导出到微软Excel电子表格中的jQuery插件。该插件能够根据你的须要导出表格中的内容，不须要的行能够不导出。它文件体积小，使用很是方便。

jquery-table2excel插件的github地址为：https://github.com/rainabba/jquery-table2excel

注意导出的Excel文件的格式，默认导出为.xlsx格式的excel文件，须要excel2010以上的版本才能打开，若是是使用低版本的excel，能够手动将文件扩展名修改成.xls。

使用方法

使用table2excel表格插件须要在页面中引入jquery和jquery.table2excel.js文件。

<script type= "text/javascript" src="js/jquery.min.js"></script>
<script type= "text/javascript" src="js/jquery.table2excel.js"></script>

若是表格中的某一行不须要导出到Excel中，能够为这一行添加.noExl class类，该class类会在插件初始化时经过参数被指定为不被导出的数据。

初始化插件

在页面DOM元素加载中完毕以后，能够经过下面的方法来初始化table2excel插件。

$( "#table2excel").table2excel({
// 不被导出的表格行的CSS class类
exclude: ".noExl",
// 导出的Excel文档的名称
name: "Excel Document Name",
// Excel文件的名称
filename: "myExcelTable"
});

配置参数

table2excel插件的可用配置参数有：

exclude：不被导出的表格行的CSS class类。
name：导出的Excel文档的名称。
filename：Excel文件的名称。
exclude_img：是否导出图片。
exclude_links：是否导出超连接
exclude_inputs：是否导出输入框中的内容。

示例：

HTML table导出到Excel中的解决办法

第一部分：html+js

1.须要使用的表格数据（先不考虑动态生成的table）

                <td>3</td>
                <td>20</td>
                <td>1</td>
                <td>4.0%</td>
                <td>林生</td>
            </tr>
        </tbody>
    </table>

2.Js代码

①利用html5的download属性，点击下载该文件

<a id="dlink"  style="display:none;"></a>
<input type="button" onclick="tableToExcel('tables', 'name', 'myfile.xls')" value="Export to Excel">

<script type="text/javascript">
        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, filename) {
                if (!table.nodeType) table = document.getElementById(table)
                var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
    
                document.getElementById("dlink").href = uri + base64(format(template, ctx));
                document.getElementById("dlink").download = filename;
                document.getElementById("dlink").click();
            }
        })()
    </script>

②建立ActiveXObject对象复制到表格中

<input id="Button1" type="button" value="导出EXCEL" onclick="javascript:excels('tables')" />

<script type="text/javascript">
        var timer;
        function getExplorer(){//获取浏览器
            var explorer=window.navigator.userAgent;
            if(explorer.indexOf("MSIE") >= 0|| (explorer.indexOf("Windows NT 6.1;") >= 0 && explorer.indexOf("Trident/7.0;") >= 0)){
                return 'ie';
            }else if (explorer.indexOf("Firefox") >= 0) {
                return 'Firefox';
            }else if(explorer.indexOf("Chrome") >= 0){
                return 'Chrome';
            }else if(explorer.indexOf("Opera") >= 0){
                return 'Opera';
            }else if(explorer.indexOf("Safari") >= 0){
                return 'Safari';
            }
        }
        function excels(table){
            if(getExplorer()=='ie'){
                var curTbl = document.getElementById(table);
                var oXl=new ActiveXObject("Excel.Application");//建立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 filename = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
                }catch(e){
                    window.print("Nested catch caught " + e);
                }finally{
                    oWB.SaveAs(filename);
                    oWB.Close(savechanges = false);
                    oXL.Quit();
                    oXL = null;//结束excel进程，退出完成
                    timer = window.setInterval("Cleanup();", 1);
                }
            }else{
                tableToExcel("tables");
            }
        }
        function Cleanup(){
            window.clearInterval(timer);
            CollectGarbage();//CollectGarbage,是IE的一个特有属性,用于释放内存的
        }
        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) {
                if (!table.nodeType) table = document.getElementById(table);
                var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML};
                window.location.href = uri + base64(format(template, ctx))
            }
        })();
    </script>

第二部分：分析测试
测试环境（谷歌，火狐，IE，EDGE，QQ浏览器）

①.真正起到做用的是a标签的属性，input按钮只是起到了一个过渡到download属性的做用；

其中有编码解码，须要注意中文乱码状况；

测试只有谷歌和火狐起做用，且只有谷歌下载的文件名是“下载.xls”，火狐的文件名像是编码后的~

　双核浏览器固然也只有chrome内核下有效果~~

　我比较喜欢的一点，html中合并的单元格导出到excel中继续保留合并效果~~

谷歌截图：

火狐截图:

②.主要是利用AX对象建立excel

　　在IE下不行，会提示错误“不能使用啥对象什么什么”

　　难道是须要安装Office软件？没试过。。

这几个浏览器中，谷歌的体验稍微好一点，还能够本身带个命名什么的~~，其余体验都不是很友好~~

还有其余的问题是我继续须要想的，表格内容分页状况导出？筛选条件后导出所有？等等等~

附上源码注释地址：https://github.com/Chuyue0/javascript-demo/blob/master/tableExporeExcel.html

开发过程当中有不少预料不到的事，继续加油吧！

~~~~~~~~~~~~剩到最后的解决办法是利用插件~~~~~~~~~~~~

好比github上的

1020 Star：https://github.com/kayalshri/tableExport.jquery.plugin

270 Star：https://github.com/clarketm/TableExport

159 Star：https://github.com/huanz/tableExport

说明一下，星星多的插件是有base64编码，因此还额外须要js脚本！

我的比较喜欢最少星星的库，感受明了清晰，能够按需加载~

js实现table导出Excel，保留table样式

浏览器环境：谷歌浏览器

1.在导出Excel的时候，保存table的样式，有2种方法，①是在table的行内写style样式，②是在模板里面添加样式

2.第一种方式：行内添加样式

<td style="font-size: 18px">公司一</td>

效果：

完整代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        table td {
            font-size: 12px;
            width: 200px;
            height: 30px;
            text-align: center;
            background-color: #4f891e;
            color: #ffffff;
        }
    </style>
</head>
<body>
<a download="table导出Excel" id="excelOut" href="#">table导出Excel</a>
<table cellspacing="0" cellpadding="0" border="1" id="tableToExcel">
    <thead>
    <tr>
        <td style="font-size: 18px">公司一</td>
        <td>公司二一</td>
        <td>公司三</td>
    </tr>
    </thead>
    <tbody>
    <tr>
        <td>A公司</td>
        <td>B公司</td>
        <td>C公司</td>
    </tr>
    <tr>
        <td>A公司</td>
        <td>B公司</td>
        <td>C公司</td>
    </tr>
    <tr>
        <td>A公司</td>
        <td>B公司</td>
        <td>C公司</td>
    </tr>
    <tr>
        <td colspan="3">共计</td>
    </tr>
    </tbody>
</table>
<script>
    window.onload = function () {
        tableToExcel('tableToExcel', '下载模板')
    };
    //base64转码
    var base64 = function (s) {
        return window.btoa(unescape(encodeURIComponent(s)));
    };
    //替换table数据和worksheet名字
    var format = function (s, c) {
        return s.replace(/{(\w+)}/g,
            function (m, p) {
                return c[p];
            });
    }
    function tableToExcel(tableid, sheetName) {
        var uri = 'data:application/vnd.ms-excel;base64,';
        var 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]-->' +
            ' <style type="text/css">' +
            'table td {' +
            'border: 1px solid #000000;' +
            'width: 200px;' +
            'height: 30px;' +
            ' text-align: center;' +
            '' +
            'color: #ffffff;' +
            ' }' +
            '</style>' +
            '</head><body ><table class="excelTable">{table}</table></body></html>';
        if (!tableid.nodeType) tableid = document.getElementById(tableid);
        var ctx = {worksheet: sheetName || 'Worksheet', table: tableid.innerHTML};
        document.getElementById("excelOut").href = uri + base64(format(template, ctx));
    }

</script>
</body>
</html>

3.第二种方式：在模板里面里面添加样式

在这里面添加的样式excel就能找到和识别了

var 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]-->' +
            ' <style type="text/css">' +
            'table td {' +
            'border: 1px solid #000000;' +
            'width: 200px;' +
            'height: 30px;' +
            ' text-align: center;' +
            '' +
            'color: #ffffff;' +
            ' }' +
            '</style>' +
            '</head><body ><table class="excelTable">{table}</table></body></html>';

完整代码:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        table td {

    window.onload = function () {
        tableToExcel('tableToExcel', '下载模板')
    };

    var base64 = function (s) {
        return window.btoa(unescape(encodeURIComponent(s)));
    };
    //替换table数据和worksheet名字
    var format = function (s, c) {
        return s.replace(/{(\w+)}/g,
            function (m, p) {
                return c[p];
            });
    }
    function tableToExcel(tableid, sheetName) {
        var uri = 'data:application/vnd.ms-excel;base64,';
        var 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]-->' +
            ' <style type="text/css">' +
            'table td {' +
            'border: 1px solid #000000;' +

        if (!tableid.nodeType) tableid = document.getElementById(tableid);
        var ctx = {worksheet: sheetName || 'Worksheet', table: tableid.innerHTML};
        document.getElementById("excelOut").href = uri + base64(format(template, ctx));
    }

</script>
</body>
</html>

注意：若是同时添加了行内样式和模板样式，行内的样式会覆盖模板的样式

大佬！咱们怎么变成是html格式的呢！导出的并非excel格式
！你是否是下载的时候没有设置文件的后缀?

a标签的download="table导出Exce.xls"
如<a download="table导出Exce.xls" id="excelOut" href="#">table导出Excel</a>

问题一若是没有安装 office 导出来

安装 office 就默认指定了后缀

问题二文件格式和扩展名不匹配。文件可能已损坏或不安全除非您信任其来源

没解决不影响功能

office 打开报文件格式和扩展名不匹配。文件可能已损坏或不安全除非您信任来源不然请勿打开，是否仍要打开它
