AngularJS Question

How to DRY up list in angular

This is my first time posting a question on stackoverflow so sorry if its not in the correct format.

I keep running into the same problem in angular and i'm sure there is a very simple way to solve it but for some reason i can't figure it out. I will post an example and give an explanation below.

<div class="jmc-navbar-content" ng-if="!vm.isHidden" ng-swipe-up="vm.toggleNav()">
<!-- contains the navigation/page links -->
<ul class="jmc-navbar-menu">
<li class="active"><a class="noPreventDefault" ng-click="vm.toggleNav()" ng-href="#home">Home</a></li>
<li><a class="noPreventDefault" ng-click="vm.toggleNav()" ng-href="#portfolio">Portfolio</a></li>
<li><a class="noPreventDefault" ng-click="vm.toggleNav()" ng-href="#about">About</a></li>
<li><a class="noPreventDefault" ng-click="vm.toggleNav()" ng-href="#contact">Contact</a></li>
<li><a class="noPreventDefault" ng-click="vm.toggleNav()" ng-href="#/">View source on GitHub</a></li>

Although this works i don't like having to repeat myself for all the
tags which need to have the same classes and attributes. I can think of multiple ways in which to do this with javascript but they all seem a little 'hack-y'. Is there any simple way to do this in Angular or Javascript?

Thanks for taking the time to reply, any and all constructive criticism is appreciated.


In your html use ng-repeat

And as your first li has the class as 'active', you need to use $index

<div ng-repeat = 'aVal in aVals'>
     <li ng:class="{true:'active', false:''}[$index == 0]"><a class="noPreventDefault" ng-click="vm.toggleNav()" ng-href="aVal.hrefVal">{{}}</a></li>

And in angularController

var app = angular.module("myApp", []);

.controller('myCtrl', ['$scope',
    function ($scope) {
         $scope.aVals= [
            { hrefVal: '#home', name='Home'},
            { hrefVal: '#portfolio', name='Protfolio'},
             // so on
