将HTML导出到Excel
我尝试使用JavaScript将HTML表格导出到Excel。 然后我打开Excel文件之前popup这个：
“您尝试打开的文件[file_name.xls]采用与文件扩展名”
这是我的代码：
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]--><meta http-equiv="content-type" content="text/plain; charset=UTF-8"/></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 } var a = document.createElement('a'); a.href = uri + base64(format(template, ctx)); a.download = filename + '.xls'; a.click(); } })()
