(there other questions neither helped me out) hi, know if right way filter results service i'm displaying 1 result (like detail). i know use ng-repeat , filter in view , cleanest, want have more control on because re-use of data in controller other operations. right i'm doing this: $scope.savedevents = event.getpayedevents(); //gets list service //goes through entire list , checks match angular.foreach($scope.savedevents, function(event) { if (event.idevent == $stateparams.eventid) { $scope.showevent = event; } }); //now if there match can use $scope.showevent.eventname etc not sure if easier using $filter return 1 event has correct idevent. or if has better solution, please let me know. thanks i don't see problems have, inject $filter service , 1 liner: $scope.showevent = $filter('filter')($scope.savedevents, { idevent: $stateparams.eventid }); edit: here easy way resolve result single value returned array: var sh...

i'm writing code interfaces existing library written in c. in rust code i'd able use values cpp macros. if have c include.h looks this: #define init_flag 0x00000001 i'd able use in rust this: #[link(name="mylib")] extern { pub static init_flag: c_int = init_flag; } i've looked @ other ffi code , see lot of people duplicating these values in rust instead of getting them ffi. seems little brittle, , i'd able handle more complicated things defined via cpp macros. running cpp on rust files work if i'm sure cpp macros used simple things. it impossible, , don't think possible in future. c macros bring many problems them. if want run cpp on rust sources, can manually. if don't want , if there lot of constants , don't want copy values c code rust can make c wrapper provide global variables these values: #define init_flag 0x00000001 ... const int init_flag = init_flag; you compile file, create static library , link...

let's want change image source onclick , calculations. whats happening right source changes when the function exits. (dom busy?) how can make image source updates right away , function proceeds while loop? html: <img src="http://goo.gl/l55g2p" id="imagesrc"> js: $( "#imagesrc" ).click(function() { new_imgsrc="http://goo.gl/wbhyee"; $("#imagesrc").attr('src',new_imgsrc); test = 0 { test = test + 1; console.log(test); } while (test != 50000); }); here 's jsfiddle. not sure understand correctly use timeout: settimeout(function() { //while loop here }, 1000); where 1000 means 1 second. shrink value doesn't wait long. as click() has no callback oncomplete not sure of better way achieve this.
