Question

What is the process for saving an HTML document with SaveFile.js?

I'm currently implementing a save feature for my website. Utilizing the 'SaveFile.js' module from this link: 'https://github.com/eligrey/FileSaver.js/' Once the user clicks on the save button, the goal is to have the entire document download as an HTML file with all its elements intact like input boxes, images, and so on. However, instead of the full HTML document, only some text from an HTML page seems to be downloaded:

What could be causing this issue?

<button type="button" name="btnSave" onclick="saveHTMLFile()">Save</button>

<script>
  function saveHTMLFile(){
  let fileToSave=document;
  let blob = new Blob([fileToSave],{type:"text/html;charset=utf-8"});
  saveAs(blob,'SavedOutline.html')
}
  </script>

Answer №1

To convert the document into a string, you will need to serialize it. Consider using

document.documentElement.outerHTML

instead of just document.

document.documentElement retrieves the root element of the document
el.outerHTML provides the HTML content of the element in string format

In your code:


<button type="button" name="btnSave" onclick="saveHTMLFile()">Save</button>

<script>
  function saveHTMLFile(){
  let fileToSave=document.documentElement.outerHTML;
  let blob = new Blob([fileToSave],{type:"text/html;charset=utf-8"});
  saveAs(blob,'SavedOutline.html')
}
  </script>

Perhaps this snippet of code could potentially be helpful in your situation.

var text = new Text(["Goodbye, universe!"], "goodbye universe.txt", {type: "text/plain;charset=utf-8"});
TextSaver.saveAs(text);

It should be noted that the use of new Blob() is primarily intended for Storing text data.
