html中将table数据直接导入到excel中

方法一、通过<a>标签（可定义文件名称）：

导出到excel方法：

var tableToExcel2 = (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></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, filename) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
document.getElementById("dlink").href = uri + base64(format(template, ctx));
document.getElementById("dlink").download = filename + ".xls";
document.getElementById("dlink").click();
}
})();

方法二、直接使用<button>标签：

脚本：

//将table数据直接导入到excel中
var timer;
function excels(table, fileName) {
if (getExplorer() == 'ie') {
var curTbl = document.getElementById(table);
var oXl = new ActiveXObject("Excel.Application");//创建AX对象excel
var oWB = oXL.Workbooks.Add();//获取workbook对象
var xlsheet = oWB.Worksheets(1);//激活当前sheet
var sel = document.body.createTextRange();
sel.moveToElementText(curTbl);//把表格中的内容移到TextRange中
sel.select;//全选TextRange中内容
sel.execCommand("Copy");//复制TextRange中内容
xlsheet.Paste();//粘贴到活动的EXCEL中
oXL.Visible = true;//设置excel可见属性
try {
var filename = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
} catch (e) {
window.print("Nested catch caught " + e);
} finally {
oWB.SaveAs(filename);
oWB.Close(savechanges = false);
oXL.Quit();
oXL = null;//结束excel进程，退出完成
timer = window.setInterval("Cleanup();", 1);
}
} else {
tableToExcel(table, fileName);
}
}
function Cleanup() {
window.clearInterval(timer);
CollectGarbage();//CollectGarbage,是IE的一个特有属性,用于释放内存的
}
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></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, name) {
if (!table.nodeType) table = document.getElementById(table);
var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML };
window.location.href = uri + base64(format(template, ctx))
}
})();

注意：IE下需要安装OFFICE excel才可以导出。
