The impact of array splicing on data manipulation

Question

The impact of array splicing on data manipulation

I have a $scope array variable that I'm using to generate tabs on the front end, but I'm struggling with implementing a remove tab function. The code for removing tabs is as follows:

function removeTab(index) {
    $scope.tabs.splice(index, 1);
};

For creating the tabs, here is the code snippet:

<tabset class="tab-container">
    <tab id = "tabContent" ng-repeat="tab in tabs" active="tab.active" ng-select="select"> <!-- the tab highlight directive -->
        <tab-heading>
            <span>{{tab.title}}</span>
            <i class="glyphicon glyphicon-remove" ng-click="removeTab($index)"></i> <!-- the tab close button -->
        </tab-heading>

        <textarea ui-codemirror= "{ onLoad : codemirrorLoaded }"></textarea>

    </tab>
</tabset>

When I attempt to close a single tab using the removeTab button after opening multiple tabs, all tabs unexpectedly close along with the console clearing itself. It's a puzzling issue that I am currently investigating.

Thank you for your assistance!

I made a slight adjustment to your code to enhance the visuals. Here's what I changed:

//Original function
var removeTab = function(index){
   $scope.tabs.splice(index,1);
}
__________
//Updated version
$scope.removeTab = function(index){
   $scope.tabs.splice(index,1);
}

var app = angular.module('tabco',[]);

app.controller('TabCtrl', ['$scope', function($scope){
  $scope.tabs = [{value:1},{value:2},{value:3},{value:4}];
  $scope.removeTab = function(index){
    $scope.tabs.splice(index,1);
  }
}]);

.tabcont{
border:1px solid #ccc;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
   <div ng-app="tabco" class="tab-container"  ng-controller="TabCtrl">
    <div class="tabcont" ng-repeat="tab in tabs" > <!-- the tab highlight directive -->
      <div>
        <span>{{tab.value}}</span>
        <i class="glyphicon glyphicon-remove" ng-click="removeTab($index)">X</i> <!-- the tab close button -->
      </div>

    <textarea></textarea>
