问题描述
我有一个文本区域,其中包含要输出到用户下载的文本文件的文本。
I have a text area that contains text that I want to output to a text file for users to download.
我使用此功能来抓取它用户点击保存按钮
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'});
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();
}
但不保留换行符。它们存在于document.getElementById(inputText).value;但不在从blob创建的文本文件中。
But the line breaks aren't retained. They exist in document.getElementById("inputText").value; but not in the text file created from the blob.
推荐答案
我遇到了同样的问题。这似乎对我有用:
I ran into the same problem. This seems to be working for me:
textToWrite = textToWrite.replace(/\n/g, "\r\n");
