首先導入 xlsx.full.min.js
建立表格數據
下面是關鍵代碼
<a download="表格導出excel" id="excelOut" href="#" class="btn_a">導出</a>
//base64轉碼
var base64 = function (s) {
return window.btoa(unescape(encodeURIComponent(s)));
};
//替換table數據和worksheet名字
var format = function (s, c) {
return s.replace(/{(\w+)}/g,
function (m, p) {
return c[p];
});
}
function tableToExcel(tableid, sheetName) {
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"><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]-->' +
' <style type="text/css">' +
'table td {' +
'border: 1px solid #000000;' +
'width: 100px;' +
'height: 30px;' +
' text-align: center;' +
' }' +
'</style>' +
'</head><body ><table class="excelTable">{table}</table></body></html>';
if (!tableid.nodeType) tableid = document.getElementById("materials_table");
var ctx = {worksheet: sheetName || 'Worksheet', table: tableid.innerHTML};
document.getElementById("excelOut").href = uri + base64(format(template, ctx));
}
