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>选中此选项以从servlet下载文件
