javascript - Javascript 数组中最后一项后的换行符

Question

我有这段代码，它允许我使用二维数组下载 CSV 文件，但我需要在第一个数组中的最后一项之后有一个换行符。 (就在一些其他信息之后。

<script type="text/javascript">

    // 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');
</script>

所以要明确的是，我现在得到的结果是:

name1;city1;some other infoname2;city2;more info

我需要它是:

name1;city1;some other info
name2;city2;more info

提前非常感谢。

无论您使用什么方式显示文件，都可能需要 Windows 行结尾而不是 UNIX 行结尾。尝试 \r\n 而不仅仅是 \n。
