I am working on a project where at some point I want to add the functionality of saving the current webpage as HTML, also in pdf, I am saving page in pdf format by this javascript function window.print() now I want to save it as HTML, but can't find a way to do this, I hope there would be some function to save as HTML. If you know, let me know, it would be a great help. Note that you can save the current webpage as Html by a keyboard shortcut Ctrl S, and print the page using the keyboard shortcut Ctrl P.

CodePudding user response：

Use document.querySelector("html").innerHTML to get all the HTML of an page.

Then you have a variable containing the entire document as a string - we can download it with the following function:

function download(filename, text) {
 var element = document.createElement('a');
 element.setAttribute('href', 'data:text/plain;charset=utf-8,'   
 encodeURIComponent(text));
 element.setAttribute('download', filename);

  element.style.display = 'none';
  document.body.appendChild(element);

  element.click();

  document.body.removeChild(element);
}
