Clicking 加载更多 in the 多栏目文章 widget showed no skeleton at all — the
list simply stayed still until the response arrived, then the new cards
appeared. The homepage stream, archives and comments already had a working
skeleton; the widget's AJAX load goes through a different client and never
found its loader.
Root cause was DOM placement, not visibility: ContentRenderer emitted
.post_ajax_loader as a *sibling* of .widget-ajaxpager, while the widget REST
client resolves it with container.querySelector('.post_ajax_loader'). The
node existed but could never match, so .is-loading was never added and the
skeleton stayed display:none. Inactive tab panes had the same shape, and the
direct-load branch of ajaxpager() emitted no loader at all.
Changes, all following the reference theme's post_ajax() contract in
zibll/js/main.js (beforeSend anchors the loader to the end of the list;
success only hides it, never removes it):
- ContentRenderer: nest the loader inside .widget-ajaxpager for both the
direct-load and inactive-tab branches, and drop the sibling append.
- widgets/frontend.js: anchorLoader() moves the loader to the end of the
list before .ajax-pag on every request; appended cards are inserted before
it; a replace preserves the node instead of wiping it with innerHTML; a
fallback loader is created when the DOM has none; loadItems() now returns
its promise; drop the unreachable is-loading auto-load branch.
- Message centre, user-home panels and the search page switch from spinner /
opacity feedback to the same .posts-item-shaped skeleton, so all AJAX
surfaces share one loading contract.
- Remove the second, never-wired skeleton system (.aksrt-skeleton-* in
core-ui.css) and the dead spinner stylesheets/rules (skeleton.css,
ajax-spinner.css, .load-more__*, --skeleton-base/--skeleton-shine) plus the
unregistered assets/js/waterfall.js.
- Extend the widget, message-centre, user-home and asset-ledger contract
tests to pin the loader inside the container, the class-only visibility
switch, and the absence of the deleted dead code.
Verified: 470 node tests, 136 PHP widget assertions, admin-contract and
widget-system audits all green; rebuilt public assets after the CSS/JS
removals.
