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);

//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);

简单地尝试一下，这里的一些答案不处理unicode数据和有逗号的数据，例如date。

function downloadUnicodeCSV(filename, datasource) {
    var content = '', newLine = '\r\n';
    for (var _i = 0, datasource_1 = datasource; _i < datasource_1.length; _i++) {
        var line = datasource_1[_i];
        var i = 0;
        for (var _a = 0, line_1 = line; _a < line_1.length; _a++) {
            var item = line_1[_a];
            var it = item.replace(/"/g, '""');
            if (it.search(/("|,|\n)/g) >= 0) {
                it = '"' + it + '"';
            }
            content += (i > 0 ? ',' : '') + it;
            ++i;
        }
        content += newLine;
    }
    var link = document.createElement('a');
    link.setAttribute('href', 'data:text/csv;charset=utf-8,%EF%BB%BF' + encodeURIComponent(content));
    link.setAttribute('download', filename);
    link.style.visibility = 'hidden';
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
};

从react-admin:

function downloadCsv(csv, filename) {
    const fakeLink = document.createElement('a');
    fakeLink.style.display = 'none';
    document.body.appendChild(fakeLink);
    const blob = new Blob([csv], { type: 'text/csv' });
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        // Manage IE11+ & Edge
        window.navigator.msSaveOrOpenBlob(blob, `${filename}.csv`);
    } else {
        fakeLink.setAttribute('href', URL.createObjectURL(blob));
        fakeLink.setAttribute('download', `${filename}.csv`);
        fakeLink.click();
    }
};

downloadCsv('Hello World', 'any-file-name.csv');

在Chrome 35更新中，下载属性行为发生改变。

https://code.google.com/p/chromium/issues/detail?id=373182

要在chrome中工作，使用这个

var pom = document.createElement('a');
var csvContent=csv; //here we load our csv data 
var blob = new Blob([csvContent],{type: 'text/csv;charset=utf-8;'});
var url = URL.createObjectURL(blob);
pom.href = url;
pom.setAttribute('download', 'foo.csv');
pom.click();

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();
        });
