AngularJS set initial active class

All we need is an easy explanation of the problem, so here it is.

I’m using Bootstrap tabs with an Angular ng-repeat.

The problem I’m running into is that the first li and the first each need an active class. Bootstrap takes care of that after a tab is clicked but, as you can see, not on load.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

All you have to do is put an ng-class directive on the tab and tab pane that you would like active initially. You can change the expression from $index == 0 in the ng-class directive to whatever you would like. This could use a function or variable in your scope.

Here is a JS Fiddle showing how to do this:

And here is the final code… notice the ng-class directives:

<div ng-app>
    <div ng-init="names = [{name:'one'}, {name:'two'}, {name:'three'}, {name:'four'}, {name:'five'}]">
    <ul class="nav nav-tabs">
    <li ng-repeat="name in names" ng-class="{active: $index == 0}">
      <a href="#tab{{$index + 1}}" rel="nofollow noreferrer noopener" data-toggle="tab">Week {{acute.Week}}</a>
  <div class="tab-content">
    <div class="tab-pane fade in" id="tab{{$index + 1}}" ng-repeat="name in names" ng-class="{active: $index == 0}">
      <p>{{$index + 1}}</p>

Note: Use and implement method 1 because this method fully tested our system.
