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

您可以在原生JavaScript中做到这一点。你必须把你的数据解析成正确的CSV格式(假设你在问题中描述的数据使用数组的数组):

const rows = [
    ["name1", "city1", "some other info"],
    ["name2", "city2", "more info"]
];

let csvContent = "data:text/csv;charset=utf-8,";

rows.forEach(function(rowArray) {
    let row = rowArray.join(",");
    csvContent += row + "\r\n";
});

或者更简单的方法(使用箭头函数):

const rows = [
    ["name1", "city1", "some other info"],
    ["name2", "city2", "more info"]
];

let csvContent = "data:text/csv;charset=utf-8," 
    + rows.map(e => e.join(",")).join("\n");

然后就可以使用JavaScript的窗口了。open和encodeURI函数下载CSV文件，如下所示:

var encodedUri = encodeURI(csvContent);
window.open(encodedUri);

编辑:如果你想给你的文件一个特定的名字，你必须做一些不同的事情，因为这是不支持访问一个数据URI使用窗口。开放的方法。为了实现这一点，你可以创建一个隐藏的<a> DOM节点，并将其下载属性设置如下:

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

link.click(); // This will download the data file named "my_data.csv".

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('，')。

这里有许多将数据转换为CSV的解决方案，但几乎所有的解决方案都有各种各样的注意事项，即在不出错的情况下正确格式化数据类型。

为什么不使用一些经过验证的东西:Papa Parse

Papa.unparse(data[, config])

然后只需结合这与本地下载解决方案之一在这里，如。@ArneHB的那个看起来不错。

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")

//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);
