I'm changing an IFRAME's src in order to reload it, its working fine and firing the onload event when its HTML loads.
But it adds an entry to the history, which I don't want. Is there any way to reload an IFRAME and yet not affect the history?

Using self. location. reload() will reload the iframe. This works from JavaScript inside the current iFrame.
To check if iframe is loaded or it has a content with JavaScript, we can set the iframe's onload property to a function that runs when the iframe is loaded. document. querySelector("iframe"). onload = () => { console.
IFrames are not obsolete, but the reasons for using them are rare. Using IFrames to serve your own content creates a "wall" around accessing the content in that area. For crawlers like Google, It's not immediately clear that cotent in an iframe will be ranked as highly as if the content were simply part of the page.
Using replace() is only an option with your own domain iframes. It fails to work on remote sites (eg: a twitter button) and requires some browser-specific knowledge to reliably access the child window.
Instead, just remove the iframe element and construct a new one in the same spot. History items are only created when you modify the src attribute after it is in the DOM, so make sure to set it before the append.
Edit: JDandChips rightly mentions that you can remove from DOM, modifiy, and re-append. Constructing fresh is not required.
