Javascript error on mobile Firefox (iOS) #20240
Comments

Are you able to open the browser console to see more details? |

I haven't found a way to do that on the mobile browser yet and it doesn't happen on desktop. I'm assuming it's an issue with that particular browser version since it only happens in Firefox. It also doesn't seem to interfere with functionality but I can't be sure so I decided to open an issue ... if for no other reason than bringing awareness of it. |

That's a Firefox bug. You can reproduce it with the following code. Gitea could try to bypass it with some hacky check.
<!DOCTYPE html>
<html>
<head>
<script>
window.addEventListener('error', function(e) {alert('error');});
</script>
</head>
<body>
<div class="page-content">
</div>
<script>
const pageContent = document.querySelector('.page-content');
const el = document.createElement('div');
el.textContent = 'dummy'; // required
pageContent.append(el); // BUG, triggers the error event
// setTimeout(()=>{pageContent.append(el);}, 0); // BUG, triggers the error event
// setTimeout(()=>{pageContent.append(el);}, 500); // no bug .....
</script>
</body>
</html> |

* go-gitea#20240 At the moment, Firefox (iOS) (10x) has an engine bug. See go-gitea#20240 If a script inserts a newly created (and content changed) element into DOM, there will be a nonsense error event reporting: Script error: line 0, col 0. This PR ignores such nonsense error event. Fix go-gitea#20240

The fix has been deployed to try.gitea.io. I did a quick test, it seems fine now. |

Yep; all good here. |
