Timo Tijhof e3cdfaa9fe mw.ViewPageTarget: Performance improvements for section edit links ... Follows-up I4b9c47fd65a700a: * Remove unused closingBracketSymbol. * Moving veSectionEditUri and sectionEditUri inline as it is only used once. This will allow it to be easily dereferenced (instead of likely staying in memory due to being claimed by remaining closures "expand" and "expandSoon" which will continue to claim and enjoy access to this scope. Also changed it to use the attr() callback so that we don't access `$editLink.attr( 'href' )` twice. * Add various comments explaining this non-obvious approach. Though it makes sense (eventually) and more elaborate details are in the original commitmsg, that is no excuse for a 100 line function without a single comment, especially with all these things going on. * Use "shrink" instead of "contract" (seems more common in context of web UI elements and less ambgiuous in English). * Remove redundant toString in `new mw.Uri( veEditUri )`. Aside from redundant, it also had more overhead (serialising uri object to string and re-parsing). It revoked its ability to make an efficient clone by taking the mw.Uri object as input as opposed to having to parse it again. mw.Uri#clone does the same internally. * Avoid variable names like $this, that or self. Using a more descriptive name instead. * Re-use $closingBracket instead of using last() 3 times which makes 3 clones of the jQuery object with the same last element in it. * Refactor odd swapping of closingBracket-hide and middleBracket-clone-show. It now keeps the original opening/edit/closing in tact and adds devider/hidden/edit-source/outerClosing at the end. Change-Id: I5f093f2927b769fed0c6d1a40f99e73f9b653b9a		2013-06-27 13:11:38 -07:00
