here's fiddle of want do: https://jsfiddle.net/s7s07chm/7/ but want react instead of jquery. basically, put classname of element in state, , on componentdidmount update classname initiate transition. but isn't working. component rendering transitioned state. in other words, instead of sliding down, appears @ bottom beginning am doing wrong? if so, there way accomplish this? here's actual code getinitialstate: function() { return { childclass: 'child' }; }, componentdidmount: function() { this.setstate({ childclass: 'child low' }); }, the reason won't work because dom won't updated until component mounted. class you're assigning getinitialstate never appear in dom, 1 set componentdidmount will. ray mentioned, should take @ reactcsstransitiongroup.

this question has answer here: why accessing element in object using array key work? 3 answers why javascript evaluate following true, given object foo has valid property bar ? foo[[[["bar"]]]] === foo["bar"] based on operator precedence, think foo[[[["bar"]]]] trying access property array [[["bar"]]] key, why still "flatten down" same foo["bar"] ? colleagues of mine saying javascript parsers have bracket simplifying ignores brackets. don't think true since saving [[["foo"]]] variable test gives same result: > test = [[["bar"]]] [array[1]] > foo["bar"] = 5 5 > foo[test] 5 what aspect of language or parser causing behavior? thanks! javascript bracket notation accepts expression, converts value of expression string. if pass in array, attemp...

i have platform specific modifications checked-in files. how force git keep local version , ignore remote 1 when merge remote branch? basically, git-ignore, files tracked repository. the use-case i'm pushing 1 branch, , pulling branch on different platforms testing. doing testing first time on each platform required running ./configure script modified files platform-specific customizations. since changes automatically generated, don't want commit them history. add files .gitignore, however, of files part of original repository, git ignore ignored. this possibly duplicate of git pull keeping local changes first answer there in particular seems best solution if platform-specific changes aren't committed.
