如果有人需要这个敲除js，它的工作好基本上提出的解决方案:

html:

<a data-bind="attr: {download: filename, href: csvContent}">Download</a>

视图模型:

// for the download link
this.filename = ko.computed(function () {
    return ko.unwrap(this.id) + '.csv';
}, this);
this.csvContent = ko.computed(function () {
    if (!this.csvLink) {
        var data = ko.unwrap(this.data),
            ret = 'data:text/csv;charset=utf-8,';

        ret += data.map(function (row) {
            return row.join(',');
        }).join('\n');

        return encodeURI(ret);
    }
}, this);

这是基于已接受答案的修改答案，其中数据将来自JSON。

            JSON Data Ouptut:
             0 :{emails: "SAMPLE Co., peter@samplecompany.com"}, 1:{emails: "Another CO. , ronald@another.com"}


            JS:
            $.getJSON('yourlink_goes_here', { if_you_have_parameters}, function(data) {
            var csvContent = "data:text/csv;charset=utf-8,";
            var dataString = '';
             $.each(data, function(k, v) {
                dataString += v.emails + "\n";
             });

            csvContent += dataString;

            var encodedUri = encodeURI(csvContent);
            var link = document.createElement("a");
            link.setAttribute("href", encodedUri);
            link.setAttribute("download", "your_filename.csv");
            document.body.appendChild(link); // Required for FF

            link.click();
        });

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');

运行代码片段将下载csv格式的模拟数据

归功于dandavis https://stackoverflow.com/a/16377813/1350598

您可以使用下面的代码段使用Javascript将数组导出到CSV文件。

这也可以处理特殊字符部分

var arrayContent = [["Séjour 1, é,í,ú,ü,ű"],["Séjour 2, é,í,ú,ü,ű"]];
var csvContent = arrayContent.join("\n");
var link = window.document.createElement("a");
link.setAttribute("href", "data:text/csv;charset=utf-8,%EF%BB%BF" + encodeURI(csvContent));
link.setAttribute("download", "upload_data.csv");
link.click();
