javascript - angular active link navigation -

-

angular beginner here. i'm trying have link active once i'm on given page. found quite couple of examples none of work, must i'm doing wrong.

this i've been trying (controller) :

angular.module('myapp')   .controller('homectrl', ['$scope', function ($scope) {     $('body').addclass('homepage');      $scope.isactive = function(route) {       return route === $location.path();     }   }]);

html :

<li "ng-class" = "{active:isactive('/') || isactive('/home')}">  home </li> <li "ng-class" = "{active:isactive('/about')}">  </li> <li "ng-class" = "{active:isactive('/contact')}">  contact </li>

application :

var app = angular     .module('myapp', [         'nganimate',         'ngcookies',         'ngresource',         'ngroute',         'ngsanitize',         'ngtouch',         'templates',          'ng-token-auth'     ]).config(['$routeprovider', '$locationprovider', function ($routeprovider, $locationprovider) {         $routeprovider             .when('/home', {                 templateurl: 'home.html',                 controller: 'homectrl'             })             .when('/', {                 templateurl: 'home.html',                 controller: 'homectrl'             })             .when('/contact', {                 templateurl: 'contact.html',                 controller: 'contactctrl'             })             .when('/about', {                  templateurl: 'about.html',                  controller: 'aboutctrl'              })             .otherwise({               redirectto: '/'             });         $locationprovider.html5mode({           enabled: true,           requirebase: false         });     }])

so no matter on page i'm located at, ng-class nothing no errors in console. if home:

<li "ng-class" = "{active:true}">      home     </li>

then active class on link, , output :

<li ng-class="{active:true}" class="active"> home </li>

what doing wrong here? why doesn't interpolate function isactive should?

you cannot have logic check active link inside homectrl 1 of routes. when other routes loaded there no homectrl loaded.

there should controller defined outside ng-view, such rootctrl. isactive function should added it.

since child view scope have access parent scope, can use isactive in child views normally.

update: consider html

<body ng-controller='rootctrl'>    <div ng-view></div> </body>

add isactive function on rootctrl.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
