There are many ways you can do this. Here there is one of them
Create a controller and set a var called currentLink like this
//...
.controller('headerCtrl', function($scope){
$scope.currentLink = 1;
$scope.set = function(link){
$scope.currentLink = link;
}
});
//...
now in your html modify your code like this:
<div class="header" ng-controller="headerCtrl">
<!--...-->
<div class="collapse navbar-collapse" id="js-navbar-collapse">
<ul class="nav navbar-nav">
<li ng-class="{'active': currentLink == 1}">1</li>
<li ng-class="{'active': currentLink == 2}"><a ng-href="#!/page2" ng-click="headerCtrl.set(2);">2</a></li>
<li ng-class="{'active': currentLink == 3}" ><a ng-href="#!/page3" ng-click="headerCtrl.set(3);">3</a></li>
<li ng-class="{'active': currentLink == 4}"><a ng-href="#!/page4" ng-click="headerCtrl.set(4);">4</a></li>
<!-- and so on-->
</ul>
<!--...-->
</div>
This way with ng-class you switch from active or not every link and with ng-click you set that link as active when clicked;
