path通过使用以下方法从servlet 传递到Java脚本来进行尝试：request.setAttribute(arg0, arg1)
<script type='text/javascript'>
function saveTextAsFile()
{
var textToWrite = "SOME TEXT YOU WANT TO WRITE"
var textFileAsBlob = new Blob([textToWrite], {type:'.txt'});
var fileNameToSaveAs = "my.txt";
var downloadLink = document.createElement("a");
downloadLink.download = fileNameToSaveAs;
if (window.webkitURL != null)
{
downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);
}
else
{
downloadLink.href = window.URL.createObjectURL(textFileAsBlob);
downloadLink.style.display = "none";
document.body.appendChild(downloadLink);
}
}
</script>
