javascript - 将文本文件写入Blob时无法保留换行符

我有一个文本区域，其中包含要输出到文本文件以供用户下载的文本。

当用户单击“保存”按钮时，我正在使用此功能来抓取它

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

    var downloadLink = document.createElement("a");
    downloadLink.download = 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);
    }
    else
    {
        // Firefox requires the link to be added to the DOM
        // before it can be clicked.
        downloadLink.href = window.URL.createObjectURL(textFileAsBlob);
        downloadLink.onclick = destroyClickedElement;
        downloadLink.style.display = "none";
        document.body.appendChild(downloadLink);
    }

    downloadLink.click();
}

但是不会保留换行符。它们存在于document.getElementById(“inputText”)。value;中；但不在从Blob创建的文本文件中。

最佳答案

我遇到了同样的问题。这似乎为我工作:

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