Updating entire DOM in javascript

Implementing undo-redo functionality in my project has proven to be quite complex, as every change affects numerous elements. I believe that saving and restoring the entire page may be the most effective solution. However, I have encountered issues with missing .data() parameters of DOM elements. The functions I am using are:

// save
var documentCopy = document.documentElement.cloneNode(true);

// restore
document.replaceChild(
documentCopy,
document.documentElement
);

How can I save and restore the entire DOM while retaining jQuery.data() of elements?

Answer №1

If you're looking for a solution, consider using jQuery's clone method instead. Make sure to use it with two true parameters, although be cautious as it may result in slower performance. Have you explored other options aside from this? Perhaps replacing a smaller section of the document could yield better results?

It's important to note that document.documentElement doesn't seem to play well with this approach, and using it with the document's body can result in loss of data from the original elements (surprising right?). Check out this test example to see how it works.
