Subject: luci-base: cbi.js: utilize node.closest() if available
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6b8fc99fd5897d9a0d959d567a02113ef5b2a328;p=oweals%2Fluci.git

luci-base: cbi.js: utilize node.closest() if available

Use node.closest() in findParent() when available since it should be faster
than manaually traversing the ancestor chain.
