javascript - jQuery , changing value with live odds - this 1st time posting here, sorry if i'm not gonna clear wiht question first shoot :). ok, allow me explain i'm stuck. got portal odds can changed second, means, if u pick 1 odd now, can changed second, means u have alter bet on odd. this site best illustration of wanna get. http://www1.betuniq.eu/it/live (pick match u can see odds betting) when pick odd, odd hovered css class, when same odd alter it's value, hover disappears. wanna next. when odd alter value wanna color of hover ?! in short, thats problem. hope wrote understandable. kind regards it can done jquery. it's this. not elegant way, maybe else can suggest littlebit more clear solution. till time, can check this: jquery <script type="text/javascript"> $(function() { $('.odd').click(function() { if (!$(this).hasclass('clicked')) { $(this).addclass('click...

List of Tuples as a function Parameter in Haskell - how define function parameter list of tuples? illustration of input [("hey", false), ("you", true)] my function takes list of tuples as: [(string, bool)] here looks like: afunc :: [(string, bool)] -> bool afunc ???? = so fill in ???? able access tuple? help great. thanks. edit: afunc :: [(string, bool)] -> bool afunc atuple = mapm_ lookup atuple? so how access tuple in function? doesn't work. it looks you're trying implement own version of lookup . can write simple version using list comprehension: lookup' :: string -> [(string,bool)] -> bool lookup' k lkp = head $ [v | (k',v) <- lkp, k'==k] or using filter : lookup'' :: string -> [(string,bool)] -> bool lookup'' k lkp = snd $ head $ filter ((==k) . fst) lkp notice these versions unsafe - is, they'll fail ugly , uninformative error if list doesn't con...
