js代码将html导出为Excel的方法：
直接上源码:
<script type="text/javascript" language="javascript"> var idTmr;
function getExplorer() {
var explorer = window.navigator.userAgent ;
//ie
if (explorer.indexOf("MSIE") >= 0) {
return 'ie';
}
//firefox
else if (explorer.indexOf("Firefox") >= 0) {
return 'Firefox';
}
//Chrome
else if(explorer.indexOf("Chrome") >= 0){
return 'Chrome';
}
//Opera
else if(explorer.indexOf("Opera") >= 0){
return 'Opera';
}
//Safari
else if(explorer.indexOf("Safari") >= 0){
return 'Safari';
}
}
function method1(tableid) {//整个表格拷贝到EXCEL中
if(getExplorer()=='ie')
{
var curTbl = document.getElementById(tableid);
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 fname = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
} catch (e) {
print("Nested catch caught " + e);
} finally {
oWB.SaveAs(fname); oWB.Close(savechanges = false);
//xls.visible = false;
oXL.Quit();
oXL = null;
//结束excel进程，退出完成
//window.setInterval("Cleanup();",1);
idTmr = window.setInterval("Cleanup();", 1); }
}
else
{
tableToExcel(tableid)
}
}
function Cleanup() {
window.clearInterval(idTmr);
CollectGarbage();
}
