Could someone help me save the contents of a HTML5 textArea to file, preferably using JavaScript?

First of all, the file format for "ecc.plist" was not recognizable anywhere. Second of all, in order for the code to work on the desktop in Safari, Chrome, and Firefox, you have to use an existing anchor tag and not create one (document.createElement('a')). The destroyClickedElement approach only works in Chrome, because it is so forgiving and lenient. And, in order for the download to work in Firefox, you have to have document.body.appendChild(downloadLink.download);</p> <p>I also had wanted to save my local storage text to a file for download and the code works on desktop for Safari, Chrome and Firefox on Mac. However, I think it is impossible in iOS to save the Blob() anywhere with Chrome or Firefox. It does work, interestingly enough in Safari. For example, I can save the text file to my Wunderlist app. Here is the link my repo on Github: The Cat Whisperer on Github gh-pages</p> <p>Here is the JavaScript code:</p> <pre><code>const fileDownloadButton = document.getElementById('save'); function localStorageToFile() { const csv = JSON.stringify(localStorage['autosave']); const csvAsBlob = new Blob([csv], {type: 'text/plain'}); const fileNameToSaveAs = 'local-storage.txt'; const downloadLink = document.getElementById('save'); downloadLink.download = fileNameToSaveAs; if (window.URL !== null) { // Chrome allows the link to be clicked without actually adding it to the DOM downloadLink.href = window.URL.createObjectURL(csvAsBlob); downloadLink.target = `_blank`; } else { downloadLink.href = window.URL.createObjectURL(csvAsBlob); downloadLink.target = `_blank`; downloadLink.style.display = 'none'; // add .download so works in Firefox desktop. document.body.appendChild(downloadLink.download); } downloadLink.click(); } // file download button event listener fileDownloadButton.addEventListener('click', localStorageToFile); </code></pre> </p> <div class="appendcontent"> </div> </div> <div class="jieda-reply"> <span class="jieda-zan button_agree" type="zan" data-id='1469495'> <i class="iconfont icon-zan"></i> <em>0</em> </span> <span type="reply" class="showpinglun" data-id="1469495"> <i class="iconfont icon-svgmoban53"></i> 讨论(0) </span> <div class="jieda-admin"> </div> <div class="noreplaytext bb"> <center><div> <a href="https://www.e-learn.cn/qa/q-562750.html"> 查看其它4个回答 </a> </div></center> </div> </div> <div class="comments-mod " style="display: none;
