javascript internet explorer byte order mark -


i working on way save html table csv file. ideally, should cross-browser, , have gotten work on internet explorer. however, have gotten obvious parts working. remains unable working csv file javascript because byte order mark prepended data wish download.

i have confirmed case downloading csv file in ie , else , used hex editor view raw file, can confirm file internet explorer downloaded prepends unicode character "fffe".

please see code below this. savetable takes "<a>" node located inside table.

if can me disgnose issue , offer solution i'd grateful. please forgive faux pas on part, don't think i've ever used site of nature before. if need me provide further information please let me know , shall best on here.

function findtable(node) { // finds nodes parent table.   return (node.nodename !== "table") ? findtable(node.parentnode) : node; }  function savetable(node) {   var csv = [];   var table = findtable(node);   var rows = table.getelementsbytagname("tr");   var header = [];   var csv = [];   (var = 0; < rows.length; i++) {     if (i == 0) {       // csv stuff.       var dates = rows[i].getelementsbytagname("th");       (var j = 0; j < dates.length; j++)          (j == 0) ? header.push("") : header.push(dates[j].innerhtml);       csv.push(header.join(","));     }     else {       var rowarray = [];       var jobname = rows[i].getelementsbytagname("th")[0].innerhtml;       var times = rows[i].getelementsbytagname("td");       rowarray.push(jobname);       (var k = 0; k < times.length; k++)          rowarray.push(times[k].innerhtml);       csv.push(rowarray.join(","));     }   }    node.setattribute("href", "data:text/csv;charset=utf-8," + csv.join("%0a"));   var filename = "spreadsheet_data-" + (new date).gettime() + ".csv";    if (node.download == "")      node.setattribute("download", filename);   else {     alert("handle ie here!");     var bom = "\ufffe";     var doc = document.open("application/octet-stream", "_blank");     var data = csv.join("\r\n");     doc.charset = "utf-8";     doc.write(data.replace(bom, ""));     doc.focus();     doc.execcommand('saveas', false, filename);     doc.close();   } }

table example, it's not way have chosen myself, it's how table generated piece of software.

<table id='results' border='1'> <tr><th><a href='#' onclick='savetable(this);' id='download_link'>download data</a></th><th>2013/05/09</th><th>2013/05/10</th><th>2013/05/10</th><th>2013/05/10</th><th>2013/05/10</th></tr> <tr> <th>\pdf\exovign.pdf</th><td>8.853</td><td>9.050</td><td>8.807</td><td>8.827</td><td>8.835</td></tr> </table>

if have no absolute requirement client-side, might save lot of hassle send file server instead.
