JS直接将页面的内容作为excel下载-JZTXT

做个笔记，后续自己可以看看，将页面的一个Table直接输出为excel文件，亲测有用。

 //下载excel
        function downloadExcel() {
            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">
                    <meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">
                    <head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet>
                    <x:Name>sheet1</x:Name>
                    <x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>
                    </x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]-->
                    </head><body><table>`+ $('#idData').html() + `</table></body></html>`;
            window.location.href = uri + window.btoa(unescape(encodeURIComponent(template)));
        };
