推荐答案

Rickard Staaf 的答案已过时.要在本地使用javascript下载文件而不提示对话框，请确保在浏览器设置(chrome >>设置>>高级>>下载)中启用该文件，然后关闭在下载前请问保存每个文件的位置" .

Rickard Staaf's answer is outdated. To download a file in javascript locally without prompting a dialog box, be sure to enable it in your browser settings (chrome >> settings >> advanced >> downloads and turn off 'Ask where to save each file before downloading'.

随后，您可以使用 blob 对象像这样编写一个简单的文本文件:

Subsequently, you can write a simple text file like so using blob objects:

function save() {
  var content = ["your-content-here"];
  var bl = new Blob(content, {type: "text/plain"});
  var a = document.createElement("a");
  a.href = URL.createObjectURL(bl);
  a.download = "your-download-name-here.txt";
  a.hidden = true;
  document.body.appendChild(a);
  a.click();
}
