Releases: Digicreon/muJS
1.4.8
New feature
Fix non-GET clicks using prefetch cache and adding to history.
The "&" character in mu-target and mu-patch-target is replaced by the trigger element's ID selector, enabling relative targeting without server-generated IDs. If the trigger has no ID, one is auto-generated. Useful for reusable components (e.g. mu-target="& > .list").
Debug
Fix non-GET clicks using prefetch cache and adding to history.
Non-GET requests (POST, PUT, PATCH, DELETE) triggered by click on elements with mu-method were incorrectly treated as navigation: served from prefetch cache, stored in cache, and added to browser history. Now prefetch cache is skipped for non-GET methods in _loadExec, and _onClick defaults to history=false for non-GET methods (same as _onSubmit already does for non-GET forms). Also harmonized HTTP method comparisons in _loadExec to use lowercase like the rest of the codebase.
1.4.7
Debugs
- Include submit button name/value in form data (rework of pull request #8 from @nullterminated)
- Fix relative URL resolution with
<base>tag. - Fix mu-repeat not working when target is the trigger element

1.4.6
Fix hash link navigation triggering full page reload
Remove location.reload() fallback in _onPopState when state has no µJS flag. Browsers may fire popstate for #fragment navigation with null state, causing an unwanted reload. Simply ignoring non-µJS popstate entries is safer — this also removes the root cause of the Safari infinite loop.
1.4.5
Fix Safari infinite loop in _onPopState
Replace window.location.href assignment with location.reload() to prevent Safari from firing a spurious popstate event on same-URL assignment. Also skip _saveScroll during popstate — the history entry has already changed to the destination, so saving scroll would overwrite the wrong state.
Fix head element deduplication when tagName is lowercase
Normalize tagName with toUpperCase() in _elKey and _mergeHead before comparison. Prevents duplicate <link> and <style> elements from being added to <head> when the browser returns lowercase tagNames (e.g. XHTML documents served as application/xhtml+xml).
1.4.4
Support relative URLs and absolute same-origin URLs.
URLs like "../page.html", "page.html", and "https://same-domain.com/page" are now resolved and intercepted.
Previously, only paths starting with "/" were processed. Uses native URL constructor with same-origin check.
Refactor: code factorization.
Refactor: reduce minified size (progress bar cssText, deduplicate hasAttribute checks)
1.4.3
Debug
Fix View Transition timing and form Content-Type.
mu:after-render,pushStateandscrollran beforestartViewTransition()applied the DOM update. Post-render logic now waits forupdateCallbackDone.- Form POST sent
multipart/form-dataregardless of enctype. Now sends URL-encoded by default, multipart only forenctype="multipart/form-data".
