这个解决方案应该适用于Internet Explorer 10+， Edge，新旧版本的Chrome, FireFox, Safari， ++

已接受的答案不能在IE和Safari中使用。

// Example data given in question text var data = [ ['name1', 'city1', 'some other info'], ['name2', 'city2', 'more info'] ]; // Building the CSV from the Data two-dimensional array // Each column is separated by ";" and new line "\n" for next row var csvContent = ''; data.forEach(function(infoArray, index) { dataString = infoArray.join(';'); csvContent += index < data.length ? dataString + '\n' : dataString; }); // The download function takes a CSV string, the filename and mimeType as parameters // Scroll/look down at the bottom of this snippet to see how download is called var download = function(content, fileName, mimeType) { var a = document.createElement('a'); mimeType = mimeType || 'application/octet-stream'; if (navigator.msSaveBlob) { // IE10 navigator.msSaveBlob(new Blob([content], { type: mimeType }), fileName); } else if (URL && 'download' in a) { //html5 A[download] a.href = URL.createObjectURL(new Blob([content], { type: mimeType })); a.setAttribute('download', fileName); document.body.appendChild(a); a.click(); document.body.removeChild(a); } else { location.href = 'data:application/octet-stream,' + encodeURIComponent(content); // only this mime type is supported } } download(csvContent, 'dowload.csv', 'text/csv;encoding:utf-8');

基于上面的答案，我创建了这个函数，并在IE 11、Chrome 36和Firefox 29上进行了测试

function exportToCsv(filename, rows) {
    var processRow = function (row) {
        var finalVal = '';
        for (var j = 0; j < row.length; j++) {
            var innerValue = row[j] === null ? '' : row[j].toString();
            if (row[j] instanceof Date) {
                innerValue = row[j].toLocaleString();
            };
            var result = innerValue.replace(/"/g, '""');
            if (result.search(/("|,|\n)/g) >= 0)
                result = '"' + result + '"';
            if (j > 0)
                finalVal += ',';
            finalVal += result;
        }
        return finalVal + '\n';
    };

    var csvFile = '';
    for (var i = 0; i < rows.length; i++) {
        csvFile += processRow(rows[i]);
    }

    var blob = new Blob([csvFile], { type: 'text/csv;charset=utf-8;' });
    if (navigator.msSaveBlob) { // IE 10+
        navigator.msSaveBlob(blob, filename);
    } else {
        var link = document.createElement("a");
        if (link.download !== undefined) { // feature detection
            // Browsers that support HTML5 download attribute
            var url = URL.createObjectURL(blob);
            link.setAttribute("href", url);
            link.setAttribute("download", filename);
            link.style.visibility = 'hidden';
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        }
    }
}

上面的答案是可行的，但请记住，如果你以.xls格式打开，列~~可能会用'\t'而不是'，'分隔，答案https://stackoverflow.com/a/14966131/6169225对我来说很好，只要我在数组上使用.join('\t')而不是.join('，')。

下载CSV文件

  let csvContent = "data:text/csv;charset=utf-8,";
  rows.forEach(function (rowArray) {
    for (var i = 0, len = rowArray.length; i < len; i++) {
      if (typeof (rowArray[i]) == 'string')
        rowArray[i] = rowArray[i].replace(/<(?:.|\n)*?>/gm, '');
      rowArray[i] = rowArray[i].replace(/,/g, '');
    }

    let row = rowArray.join(",");
    csvContent += row + "\r\n"; // add carriage return
  });
  var encodedUri = encodeURI(csvContent);
  var link = document.createElement("a");
  link.setAttribute("href", encodedUri);
  link.setAttribute("download", "fileName.csv");
  document.body.appendChild(link);
  link.click();

下面是一个原生的js解决方案。

function export2csv() { let data = ""; const tableData = []; const rows = [ ['111', '222', '333'], ['aaa', 'bbb', 'ccc'], ['AAA', 'BBB', 'CCC'] ]; for (const row of rows) { const rowData = []; for (const column of row) { rowData.push(column); } tableData.push(rowData.join(",")); } data += tableData.join("\n"); const a = document.createElement("a"); a.href = URL.createObjectURL(new Blob([data], { type: "text/csv" })); a.setAttribute("download", "data.csv"); document.body.appendChild(a); a.click(); document.body.removeChild(a); } <button onclick="export2csv()">Export array to csv file</button>

//It work in Chrome and IE ... I reviewed and readed a lot of answer. then i used it and tested in both ... 

var link = document.createElement("a");

if (link.download !== undefined) { // feature detection
    // Browsers that support HTML5 download attribute
    var blob = new Blob([CSV], { type: 'text/csv;charset=utf-8;' });
    var url = URL.createObjectURL(blob);            
    link.setAttribute("href", url);
    link.setAttribute("download", fileName);
    link.style = "visibility:hidden";
}

if (navigator.msSaveBlob) { // IE 10+
   link.addEventListener("click", function (event) {
     var blob = new Blob([CSV], {
       "type": "text/csv;charset=utf-8;"
     });
   navigator.msSaveBlob(blob, fileName);
  }, false);
}

document.body.appendChild(link);
link.click();
document.body.removeChild(link);
