如何导出多个HTML表格，以优秀？
我有一个有3个表格的网页，我想把它们全部导出到同一个excel文件中。 我希望每个表格都在自己的表格中，但是把它们都放在同一张表格上也可以。 一些谷歌search后，我所看到的是一个表格出口到一个Excel表。
var tablesToExcel = (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>' , templateend = '</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head>' , body = '<body>' , tablevar = '<table>{table' , tablevarend = '}</table>' , bodyend = '</body></html>' , worksheet = '<x:ExcelWorksheet><x:Name>' , worksheetend = '</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>' , worksheetvar = '{worksheet' , worksheetvarend = '}' , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) } , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) } , wstemplate = '' , tabletemplate = ''; return function (table, name, filename) { var tables = table; for (var i = 0; i < tables.length; ++i) { wstemplate += worksheet + worksheetvar + i + worksheetvarend + worksheetend; tabletemplate += tablevar + i + tablevarend; } var allTemplate = template + wstemplate + templateend; var allWorksheet = body + tabletemplate + bodyend; var allOfIt = allTemplate + allWorksheet; var ctx = {}; for (var j = 0; j < tables.length; ++j) { ctx['worksheet' + j] = name[j]; } for (var k = 0; k < tables.length; ++k) { var exceltable; if (!tables[k].nodeType) exceltable = document.getElementById(tables[k]); ctx['table' + k] = exceltable.innerHTML; } //document.getElementById("dlink").href = uri + base64(format(template, ctx)); //document.getElementById("dlink").download = filename; //document.getElementById("dlink").click(); window.location.href = uri + base64(format(allOfIt, ctx)); } })(); 和HTML
<html> <head> <title>JS to Excel</title> </head> <body> <table id="1"> <tr><td>Hi</td></tr> <tr><td>Hey</td></tr> <tr><td>Hello</td></tr> </table> <table id="2"> <tr><td>Night</td></tr> <tr><td>Evening</td></tr> <tr><td>Nite</td></tr> </table> <a id="dlink" style="display:none;"></a> <input type="button" onclick="tablesToExcel(['1', '2'], ['first', 'second'], 'myfile.xls')" value="Export to Excel"> <script src="~/Views/JS/JSExcel.js" type="text/javascript"></script> </body> </html>
注：这不适用于IE浏览器（'数据太小'错误），并在Firefox上这两个表放在同一张表。
也感谢这个线程 – HTML表格到Excel的Javascript
//function1
$scope.exportXlsSheets = function (datasets) { var xlsString = '<?xml version="1.0"?>\ <ss:Workbook xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">'; for(var key in dict){ var arr_of_entities= dict[key].arr; xlsString += $scope.getSheet(arr_of_entities); } xlsString += '</ss:Workbook>'; var a = document.createElement('a'); a.href = 'data:application/vnd.ms-excel;base64,' + $scope.base64(xlsString); a.target = '_blank'; a.download = 'test1.xls'; document.body.appendChild(a); a.click(); } $scope.base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
//function2
$scope.getSheet = function (sheetName, entities) { var res = '<ss:Worksheet ss:Name="'+sheetName+"></ss:Worksheet>\ <ss:Table>'; var row = '<ss:Row>'; for ( i = 0; i < entities.length; i++) { var entity = entities[i]; row += '<ss:Cell>\ <ss:Data ss:Type="String">'+entity.value +'</ss:Data>\ </ss:Cell>'; } row += '</ss:Row>'; res += row; return res; }
这是一个更好的解决scheme，支持以最新的Excel格式导出表格，例如xlsx。 如果在Chrome上导出的行数超过3407，则接受的解决scheme将失败。

HTML
<button onclick="saveFile()">Save XLSX file</button>
JavaScript的
window.saveFile = function saveFile () { var data1 = [{a:1,b:10},{a:2,b:20}]; var data2 = [{a:100,b:10},{a:200,b:20}]; var opts = [{sheetid:'One',header:true},{sheetid:'Two',header:false}]; var res = alasql('SELECT INTO XLSX("restest344b.xlsx",?) FROM ?', [opts,[data1,data2]]); }
