, 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 }
let blob = new Blob([format(template, ctx)]);
document.getElementById("dlink").href = URL.createObjectURL(blob);
document.getElementById("dlink").download = filename;
document.getElementById("dlink").click();
}
})()
请问该怎么写才能实现呢
