When using ng-repeat with Angular ui-bootstrap and tabs, the new tab will not be selected if there are no existing tabs present

To showcase the problem I'm facing, please refer to this link: http://codepen.io/pietrofxq/pen/ZLLJdr?editors=1010

Click on "remove tabs" and then on "add tab"

The challenge at hand involves using a loop with ng-repeat to display tabs. At times, there may be no items in the array, but when one tab is added back, it should automatically be selected since it's the only tab present in the tabs array. Currently, the behavior requires clicking on the tab for Angular to recognize that it's selected. How can I ensure that the tab is selected upon addition to the array without needing a click?

Answer №1

Discovered a clever workaround to get it functioning.

Managing multiple tabs requires keeping track of each one:

$scope.tabs = {
  tabOne: 0,
  tabTwo: 0
}

<uib-tabset active="tabs.tabOne"></uib-tabset>
<uib-tabset active="tabs.tabTwo"></uib-tabset>

If the array is empty and another tab is added, the value needs to be reset within a $timeout call:

$scope.$watch("items", function() {
 $timeout(function() {
    for (var prop in $scope.tabs)
      $scope.tabs[prop] = 0 
  })
}
