1、首先，界面上要有一个html表格，该表格的内容作为导出用如<table border="1" id="dataT锾攒揉敫able"> <tr> <th>Month</th> <th>Savings</th> </tr> <tr> <td>January</td> <td>$100</td> </tr></table>
3、在js中添加这个函数var tableToExcel = (function() 辘腋粪梯{ var uri = 'data:application/即枢潋雳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)); }})();
6、点击运行，成功导出了表格，把它下载下来
