Unable to retain line breaks when writing text file as blob

I have a text area that contains text that I want to output to a text file for users to download.

I'm using this function to grab it when users click the save button

function saveTextAsFile()
    var textToWrite = document.getElementById("inputText").value;
    var textFileAsBlob = new Blob([textToWrite], {type:'text/plain'});
    var fileNameToSaveAs = document.getElementById("inputFileNameToSaveAs").value;

    var downloadLink = document.createElement("a"); = fileNameToSaveAs;
    downloadLink.innerHTML = "Download File";
    if (window.webkitURL != null)
        // Chrome allows the link to be clicked
        // without actually adding it to the DOM.
        downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);
        // Firefox requires the link to be added to the DOM
        // before it can be clicked.
        downloadLink.href = window.URL.createObjectURL(textFileAsBlob);
        downloadLink.onclick = destroyClickedElement; = "none";

But the line breaks aren't retained. They exist in document.getElementById("inputText").value; but not in the text file created from the blob.


  • I ran into the same problem. This seems to be working for me:

    textToWrite = textToWrite.replace(/\n/g, "\r\n");
