i have made calculation app in appjs. basicly bunch of: <input type=number> fields. to make more user friendly thought should replace commas dots, javascript can use actual values calculate. i've tried doing this following pice of code: $("input[type=number]").keyup(function(e){ var key = e.which ? e.which : event.keycode; if(key == 110 || key == 188){ e.preventdefault(); var value = $(this).val(); $(this).val(value.replace(",",".")); } }); in explorer 9, works expected: see fiddle but since app.js uses chromium guess thats happens in chromium. how can work around this? this happens in app: when enter number containing comma char. comma char moved right , when input box loses focus, comma removed (probably since comma char isn't allowed in type=number) when value of <input type=number> isn't valid, blank string returned. check doing ...

my app uses android them holo.noactionbar theme hide action bar , display activity . this works fine on emulator , nexus 4 ,device actionbar hidden. however when run on htc 1 , ignores android theme settings , displays action bar. might displayed on other samsung or sony devices have custom oem skins. have made sure there no references action bar or menu options in activity java file or android manifest file. so googled how hide action bar , tried how hide action bar before activity created, , show again? and wrote code public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); getwindow().requestfeature(window.feature_action_bar); getactionbar().hide(); setcontentview(r.layout.activity_my); and http://developer.android.com/guide/topics/ui/actionbar.html public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); actionbar actionbar = getsupportactionbar(); actionbar.hide(); setcontentview(r.layout.activity_my); ...

i looking way generate hexadecimal string equals out 106 bits, more fifty 3 1's , fifty 3 0's after each hex char converted binary , added together. i'd keep random possible considering parameters of request. how go keeping eye on construction of string equals out way want? for example: (a8c05779f8934b14ce96f8aa93) = (1010 1000 1100 0000 0101 0111 0111 1001 1111 1000 1001 0011 0100 1011 0001 0100 1100 1110 1001 0110 1111 1000 1010 1010 1001 0011) you can place 52 ones randomly in 104 bit number keeping track of how many ones has been placed , calculate probability next digit should one. first digit has 1/2 probability (52/104), second digit has 51/103 or 52/103 probability depending on first digit was, , on. put bits in buffer, , when full (four bits), makes hexadecimal digit can add string: dim rnd new random() dim bin new stringbuilder() dim buf integer = 0, buflen integer = 0, left integer = 52 integer = 104 1 step -1 buf <<= 1 if rnd.next...

i looking @ using graph database data relational database. way database setup, information related single item spread across multiple tables. have read, seems way go have node type corresponds each table, , each entry in table node. setting edges between nodes gets tricky. for example, have table of car parts: | part number | price | quantity in inventory | cars: | make | model | price | and table of car uses part: | model number | part number | quantity | i create node each car part, , node each car model. there :uses relationship car model each part uses. makes easy parts used in particular car, or cars contain specific part. what if wanted find cars , car parts have price? (ignoring in example car parts tend not cost as car) i.e. querying shared properties? query goes through, examining each node, , accepting or rejecting node if price not match seems not scale well. if had millions of parts in database, wouldn't slow? the way around can think of create pri...

what's difference between string.indexof() , string.lastindexof() in javascript? var temp = state.indexof("tmp"); var temp = state.lastindexof("tmp"); from mdn : the indexof() method returns index within calling string object of first occurrence of specified value, lastindexof() method returns index within calling string object of last occurrence of specified value so indexof return first occurrence of value , lastindexof return last occurence of value. example (copied mdn): var anystring = "brave new world"; var = anystring.indexof("w")); // result = 8 var b = anystring.lastindexof("w")); // result 10 both of method return -1 if value not found more : indexof lastindexof
