html 端
<！-- 固定的格式導出使用 -->
<div class="modal-header" style="display: none">
<div class="row">
<div class="col-md-6">
<h4 class="modal-title" id="myModalLabel"></h4>
</div>
<div class="col-md-4">
<h4 class="modal-title" id="tipMessageLabel"></h4>
</div>
<div class="col-md-2">
<a id="dlink" style="display: none;"></a>
</div>
</div>
</div>
<!--要導出的表格-->
<table class="layui-table" id="table"></table>
<!-- 導出按鈕-->
<input type="button" class="layui-btn" style="background-color:#438eb9" onclick="exportDataToExcel()"
href="javascript:;" value="導出"/>
js 端，當數據量很大的時候使用blob代替base64的url，測試過12M的Excel數據是可以支持導出的
function exportDataToExcel() {
var fileName;
fileName = '問卷調查統計' + ".xls";
var sheetName = 'sheet';
tableToExcel("table", sheetName, fileName, "dlink");
}
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]--></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, sheetName, fileName, linkId) {
if (!table.nodeType)
table = document.getElementById(table);
var ctx = {worksheet: sheetName || 'Worksheet', table: table.innerHTML}
var dlinkInfo = document.getElementById(linkId);
//dlinkInfo.href = uri + base64(format(template, ctx));
var blob = new Blob([format(template, ctx)], {type: "application/vnd.ms-excel"});//大數據量使用base64的url會被阻斷改爲blob
dlinkInfo.href = URL.createObjectURL(blob);
dlinkInfo.download = fileName;
dlinkInfo.click();
}
})();
