javascript - 如何在新标签页/窗口中编写文本文档？

Question

如果扩展名为 jpg，下面的代码用于在新选项卡中显示图像。

同样，如果扩展名是txt，我想在新选项卡中写一个文本文档(从base64字符串到文本)。

success: function (data) {
            var extension = fileName.split('.').pop();
            if (extension == "jpg") {
                var image = new Image();
                image.src = "data:image/jpg;base64," + data.d;
                var w = window.open("");
                w.document.write(image.outerHTML);
            }
            else if(extension == "txt") {

            }
    }

Base64 图像更简单，因为您只需将 base64 粘贴到图像源中，文本等其他内容需要解码。参见 https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding

success: function (data) {
            var extension = fileName.split('.').pop();
            if (extension == "jpg") {
                var image = new Image();
                image.src = "data:image/jpg;base64," + data.d;
                var w = window.open("");
                w.document.write(image.outerHTML);
            }
            else if(extension == "txt") {
                var w = window.open("");
                w.document.write(window.atob(data.d));
            }
    }
