2   CHANGELOG
3   2026-09-28 - Quote-price lock (Dave found this): the minus button's disabled state was only ever set when
4                ViewBasket.aspx rendered. Raising the quantity with the + button is pure client-side JS with no
5                round trip, so a line that started AT its quoted floor kept a native disabled minus button
6                forever (a disabled button fires no click at all) until "Modify Basket" was clicked - even after
7                being raised well above the floor. Added applyQtyFloor(), called after every +/- click: if the
8                button that was clicked carries a data-qtyfloor attribute (only ViewBasket's multi-line quoted
9                rows have one - everywhere else this is a no-op), it disables/enables the matching minus button
10                and shows/hides its data-qtynote note purely client-side, and refuses to go below the floor at
11                all (clamps to it) rather than letting the customer decrement past it and have the server silently
12                reset it on save. Untouched: every other use of .qtyplus/.qtyminus on the site (product cards etc.)
13                has no data-qtyfloor attribute, so applyQtyFloor does nothing for them.

55// fieldName is the "field" attribute shared by a QTY box's +/- buttons (eg "QTY-008023--L1"). Looks at the
56// MINUS button for that field: if it has a data-qtyfloor attribute (only set by ViewBasket.aspx on a
57// quote-price-locked multi-line row), clamps the textbox to that floor, and disables the minus button /
58// hides its note above the floor, enables/shows them again once back down at the floor. No-op for every
59// other +/- pair on the site, which never carries data-qtyfloor.
