来自@Default的解决方案在Chrome上完美地工作(非常感谢!)，但我有一个IE问题。

以下是一个解决方案(适用于IE10):

var csvContent=data; //here we load our csv data 
var blob = new Blob([csvContent],{
    type: "text/csv;charset=utf-8;"
});

navigator.msSaveBlob(blob, "filename.csv")

这个库有很大帮助:https://www.npmjs.com/package/json-to-csv-in-browser

它自动将json数组转换为csv文件，甚至为您提供下载功能，以防您想提示web用户下载csv文件。 它用很少的代码就像一个魅力。

import { JsonArray, download } from 'json-to-csv-in-browser'

const arr = [
    {name : ` vader`, age : 53},
    {name : "what", age : 38},
    {name : "ever", age : 22}
]
const jsonArray = new JsonArray(arr);
const str = jsonArray.convertToCSVstring();
download("my.csv", str);

干杯!

编辑:再测试一下，如果你的值上有逗号，它就不能很好地工作了

用csv数据创建一个blob。ie var blob = new blob ([data]， type:"text/csv");

如果浏览器支持保存blob，即如果window.navigator. msaveoropenblob)===true，则使用:window.navigator保存csv数据。“filename.csv”msSaveBlob (blob)

如果浏览器不支持保存和打开blob，则将csv数据保存为:

var downloadLink = document.createElement('<a></a>');
downloadLink.attr('href', window.URL.createObjectURL(blob));
downloadLink.attr('download', filename);
downloadLink.attr('target', '_blank');
document.body.append(downloadLink);

完整代码片段:

var filename = 'data_'+(new Date()).getTime()+'.csv';
var charset = "utf-8";
var blob = new Blob([data], {
     type: "text/csv;charset="+ charset + ";"
});
if (window.navigator.msSaveOrOpenBlob) {
     window.navigator.msSaveBlob(blob, filename);
} else {
    var downloadLink = document.element('<a></a>');
    downloadLink.attr('href', window.URL.createObjectURL(blob));
    downloadLink.attr('download', filename);
    downloadLink.attr('target', '_blank');  
    document.body.append(downloadLink); 
    downloadLink[0].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

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();
