How to detect when iframe starts loading another page?
问题 I'm trying to hide an element in same-origin iframe. However, this son of a bi*ch blinks for a few ms before getting hidden. So what I did was added display: none and remove it after iframe is loaded - great. But now, when user clicks inner page link of iframe, which also contains element to be hidden, it still blinks (because display:none is now removed). I need to detect when to add it again, i. e. just before another page starts to load. Testing here: https://www.w3schools.com/tags/tryit
