How to write a text document in new tab / window?

Question

Below code is used to display the image in new tab if the extension is jpg.

Similarly, I want to write a text document (from base64 string to text) in new tab if the extension is txt.

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") {

            }
    }

@Sadikhasan, That question not mentioned about the conversion of base64 string to text — Earth, Jan 07 '15 at 06:08
@JohnStephen what is not working? there is no code in your else if condition. — Jai, Jan 07 '15 at 06:09
You don't give enough context in your question, a full working example which includes how the file is read by the browser and processed would be helpful. — chiliNUT, Jan 07 '15 at 06:14

Base64 images are more trivial because you just have to stick the base64 into the image source, other things like text need to be decoded. See 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));
            }
    }

Thank You very much. Exactly the answer I need. – Earth Jan 07 '15 at 06:16 — Earth, Jan 07 '15 at 06:16
