导出excel的functionjavascript，要保留在手机栏上
function fnExcelReport_pfn() { var tab_text = '<html xmlns:x="urn:schemas-microsoft-com:office:excel">'; tab_text = tab_text + '<head><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet>'; tab_text = tab_text + '<x:Name>Test Sheet</x:Name>'; tab_text = tab_text + '<x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet>'; tab_text = tab_text + '</x:ExcelWorksheets></x:ExcelWorkbook></xml></head><body>'; tab_text = tab_text + "<table border='1px'>"; tab_text = tab_text + $('#myTable').html(); tab_text = tab_text + '</table></body></html>'; var data_type = 'data:application/vnd.ms-excel'; var ua = window.navigator.userAgent; var msie = ua.indexOf("MSIE "); if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) { if (window.navigator.msSaveBlob) { var blob = new Blob([tab_text], { type: "application/csv;charset=utf-8;" }); navigator.msSaveBlob(blob, 'myexcel.xls'); } } else { $('#persoane_fizice_nefinalizate').attr('href', data_type + ', ' + encodeURIComponent(tab_text)); $('#pf').attr('download', 'commands' + timestamp() + '.xls'); } } 我有用Excel导出表格的下一个代码，并且列有电话号码。 对于expample，我有电话号码：0123456789在expor之前我有123456789。我能做些什么来保持0？
