this question has answer here: how check if array includes object in javascript? 38 answers is there anyway shorten in javascript: if (x == 1 || x == 2 || x == 3 || x == 4) if (x == (1 || 2 || 3 || 4)) ? you can use use array.indexof [1,2,3,4].indexof(x) !== -1 you can use objects kind of hash map: //note: keys coerced strings // don't use method if looking object or if need // distinguish number 1 string "1" my_values = {1:true, 2:true, 3:true, 'foo':true} my_values.hasownproperty('foo') by way, in cases should usi "===" strict equality operator instead of == operator. comparison using "==" may lots of complicated type coercion , can surprising results sometimes.

i have application needs accept float or currency values in edit control. question must format , validate edit controls input accepts numbers, comma or dot (comma or dot depends on system locale). , formatting ##.## (45.21). want 1 method can control edit controls wehre float formatting , validating used. right have code in onchange event uses trystrtofloat method, "'' not floating point number" errors. maybe guys have done more me , have great examples how right. if want continue using same validation approach, enhance algorithm consider edge cases (and how want manage that). for example, can consider accepting empty string valid input , don't throw exception, or not. must consider how want perform user interaction in case of malformed input. example if user enters invalid number, want stop user input values @ same millisecond... or can take more natural approach (for example, validating until user thinks correct). you can manage validatio...

how sort search results in following order (query phrase, alphabetical). give example, if have documents in index, each 1 field (foodname). food names of documents are fat chicken chicken breast chicken lasagna if query search word "chicken", results in following order chicken breast chicken lasagna fat chicken please note boosting factor these documents same in indexing stage. appreciated thanks -venu i'll give high level overview of i'd do. consider using food ingredients / recipes types dictionary & assigning higher boosting words in index matches items in food dictionary. , perhaps go further, assign weights keywords in food dictionary. here's example of food ingredients dictionary .

sorry long title, question rather simple: i have 2 classes, player , role (they activerecord table) class player { ...various fields... [belongsto("roleid")] public role role {get;set;} } class role { ...various fields... [property] public string name {get;set;} } a player, can have 1 role, (for me), doesn't matter if role has 0-1-2-many players, omit hasmany attribute (my example easy, database bigger this). role behaving user-defined enum, possible this? correct way? edit 1: if have similar situation need role belogs 1 player (onetoone), again omit part "role" class (so role doesn't know association) if specify belongsto attribute , not hasmany attribute, want done, role doesn't matter if has 0-1-2-many players.

i want build application uitables , detailview. got warning called: 'selected verwaltung nav controller (verwaltung)' has 'nib name' property set 'verwaltungstableview.nib', view controller not intended have view set in manner. but think have objects in right manner. here , here can see errors , interfacebuilder. what causes warning? navigation controllers meant organise other view controllers. aren't supposed lay them out yourself. you're supposed create other view controllers, assign 1 of them navigation controller's root view controller, write code let user navigate other view controllers there. if you're trying table view controller nib show up, should assigning table view controller navigation controller's rootviewcontroller property.

my class relationship: classmaster 1----* classsessions goal: return classmasters have classsessions startdatetime greater current date, along these classsessions (filtered date). in t-sql i'd this: select * classsession join classmaster on classmaster.classid = classsession.classid classsession.startdatetime > getdate() i need realize same results in entity framework 4 query. thought work, not: var classes = ctx.classsessions .include("classmasters") .where(s => s.startdatetime > datetime.now) .select(s => s.classmaster) .tolist(); this give's me classmasters have classsession startdatetime > current date, classsessions property comes filled all classsessions, including older current date. want classsessions startdatetime > current date. what doing wrong? thank much! var masters = ctx.classmasters .where(cm => cm.classsessions.any...

amazon.com announced 1 can host static web sites in s3 bucket. went setup page @ http://docs.amazonwebservices.com/amazons3/latest/dev/index.html?websitehosting.html , created bucket static web site, , worked fine. have url of form http://[my bucket name].s3-website-us-east-1.amazonaws.com/. however, point subdomain own (e.g. static.mydomain.com) static web site @ amazon s3. has figured out how that? i appreciate can give me. it turns out make work, cannot map arbitrary subdomain arbitrary bucket. the qualified subdomain name must same s3 bucket name . suppose name of site static.mydomain.com . need create s3 bucket same name, named static.mydomain.com . once configure bucket s3 static web site, have url assigned looks http://static.mydomain.com.s3-website-us-east-1.amazonaws.com . go domain host , map subdomain url step 2. in enom.com, meant mapping host " static " address " static.mydomain.com.s3-website-us-east-1.amazonaws.com " cname rec...

i want build guitar tuner app iphone. goal find fundamental frequency of sound generated guitar string. have used bits of code auriotouch sample provided apple calculate frequency spectrum , find frequency highest amplitude . works fine pure sounds (the ones have 1 frequency) sounds guitar string produces wrong results. have read because of overtones generate guitar string might have higher amplitudes fundamental one. how can find fundamental frequency works guitar strings? there open-source library in c/c++/obj-c sound analyzing (or signal processing)? you can use signal's autocorrelation, inverse transform of magnitude squared of dft. if you're sampling @ 44100 samples/s, 82.4 hz fundamental 535 samples, whereas 1479.98 hz 30 samples. peak positive lag in range (e.g. 28 560). make sure window @ least 2 periods of longest fundamental, 1070 samples here. next power of 2 that's 2048-sample buffer. better frequency resolution , less biased estimate, use longer bu...
