下面是一个Angular友好的版本:

  constructor(private location: Location, private renderer: Renderer2) {}

  download(content, fileName, mimeType) {

    const a = this.renderer.createElement('a');

    mimeType = mimeType || 'application/octet-stream';

    if (navigator.msSaveBlob) {

      navigator.msSaveBlob(new Blob([content], {
        type: mimeType
      }), fileName);
    }
    else if (URL && 'download' in a) {

      const id = GetUniqueID();

      this.renderer.setAttribute(a, 'id', id);
      this.renderer.setAttribute(a, 'href', URL.createObjectURL(new Blob([content], {
        type: mimeType
      })));

      this.renderer.setAttribute(a, 'download', fileName);

      this.renderer.appendChild(document.body, a);

      const anchor = this.renderer.selectRootElement(`#${id}`);

      anchor.click();

      this.renderer.removeChild(document.body, a);
    }
    else {
      this.location.go(`data:application/octet-stream,${encodeURIComponent(content)}`);
    }
  };

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(); 

这里是jsfiddle工作的链接

下载CSV文件

  let csvContent = "data:text/csv;charset=utf-8,";
  rows.forEach(function (rowArray) {
    for (var i = 0, len = rowArray.length; i < len; i++) {
      if (typeof (rowArray[i]) == 'string')
        rowArray[i] = rowArray[i].replace(/<(?:.|\n)*?>/gm, '');
      rowArray[i] = rowArray[i].replace(/,/g, '');
    }

    let row = rowArray.join(",");
    csvContent += row + "\r\n"; // add carriage return
  });
  var encodedUri = encodeURI(csvContent);
  var link = document.createElement("a");
  link.setAttribute("href", encodedUri);
  link.setAttribute("download", "fileName.csv");
  document.body.appendChild(link);
  link.click();

这里有两个问题:

如何将数组转换为csv字符串 如何将该字符串保存到文件

第一个问题的所有答案(除了millimetric给出的答案)似乎都有些夸张。Milimetric提供的方法不包括其他要求，比如用引号括住字符串或转换对象数组。

以下是我的看法:

对于一个简单的csv，一个map()和一个join()就足够了:

    var test_array = [["name1", 2, 3], ["name2", 4, 5], ["name3", 6, 7], ["name4", 8, 9], ["name5", 10, 11]];
    var csv = test_array.map(function(d){
        return d.join();
    }).join('\n');

    /* Results in 
    name1,2,3
    name2,4,5
    name3,6,7
    name4,8,9
    name5,10,11

此方法还允许您在内部连接中指定除逗号之外的列分隔符。例如一个制表符:d.join('\t')

另一方面，如果你想正确地将字符串括在引号""中，那么你可以使用一些JSON魔法:

var csv = test_array.map(function(d){
       return JSON.stringify(d);
    })
    .join('\n') 
    .replace(/(^\[)|(\]$)/mg, ''); // remove opening [ and closing ]
                                   // brackets from each line 

/* would produce
"name1",2,3
"name2",4,5
"name3",6,7
"name4",8,9
"name5",10,11

如果你有一个这样的对象数组:

var data = [
  {"title": "Book title 1", "author": "Name1 Surname1"},
  {"title": "Book title 2", "author": "Name2 Surname2"},
  {"title": "Book title 3", "author": "Name3 Surname3"},
  {"title": "Book title 4", "author": "Name4 Surname4"}
];

// use
var csv = data.map(function(d){
        return JSON.stringify(Object.values(d));
    })
    .join('\n') 
    .replace(/(^\[)|(\]$)/mg, '');

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');

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');
