angularjs - creating a global variable that is assigned within an ng-repeat -

-

i trying ng-click assign variable (success) inside ng-repeat , use value outside of ng-repeat(failure) follows:

    <div class="stocksnav col s1">       <div class="mystocklist" ng-repeat="stocksinportfolio in ctrl.myportfolio.stocksinportfolio">         <ul>           <li style="position: relative"><a href ng-click="ctrl.tab = stocksinportfolio.stock._id">{{stocksinportfolio.stock.name | limitto:10}}</a></li>         </ul>       <div class="mystockview" ng-show="ctrl.tab === stocksinportfolio.stock._id">         <div class="{ active:ctrl.tab === stocksinportfolio.stock._id }">       </div>     </div>   </div> </div> <div ng-include="'/app/dashboard/partials/myindividualstock.html'"></div>

the partial wants call ctrl.tab use it's click event assigned values, such if ng-click on other instance of ng-repeat function ctrl.tab variable reassign, ctrl.tab assignment not persist outside of ng-repeat div. thought?

the ng-repeat directive (as many other directives) creates new scope, , access parent's scope variable, needs object. in other words, instead of ctrl.tab, initialize object $scope.something = {} in controller, use ctrl.something.tab in template (replace something name proper application).

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
