Assigning Values to Elements that Do Not Exist

Is there any downside to assigning values to non-existent elements using JavaScript or jQuery?

In my functions that handle dynamically created DOM elements, I sometimes set values and attributes for class elements that may not always exist.

Answer №1

By creating elements that are independent of the DOM, you have the freedom to perform any operations on them without triggering a browser redraw. This method is preferred because you can make all your modifications to the disconnected DOM element before attaching it to the document, allowing for just one redraw.

Furthermore, there is no limit to the number of classes you can assign to an element, whether they have associated styles or not.
