Question

我创建了下面的代码，它接受一个JSON对象并将其转换为通过ConvertToCSV函数分隔的逗号。我的问题是如何将变量csvData作为csv文件下载？

此代码已经在按钮单击

上执行的功能中

  var jsonObject = JSON.stringify(data);
  var toCSV = ConvertToCSV(jsonObject);
  var csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(toCSV);

使用blob在本地存储然后下载它。例如

http://jsfiddle.net/koldev/cw7w5/

var saveData = (function () {
    var a = document.createElement("a");
    document.body.appendChild(a);
    a.style = "display: none";
    return function (data, fileName) {
        var json = JSON.stringify(data),
            blob = new Blob([json], {type: "octet/stream"}),
            url = window.URL.createObjectURL(blob);
        a.href = url;
        a.download = fileName;
        a.click();
        window.URL.revokeObjectURL(url);
    };
}());

var data = { x: 42, s: "hello, world", d: new Date() },
    fileName = "my-download.json";

saveData(data, fileName);
