javascript - Why when I using track by $index will always remove the last element? -


i using ng-repeat track $index option, can not delete correct element array or object (ng-repeat remove last element).

this add button (add button created new table) : 

 $scope.current = 0;     $scope.addhockpis = function () {         $scope.repeattable.push('test' + $scope.current);         $scope.current += 1;     };

this table code:

<table id="addhockpistable{{$index}}" ng-repeat="table in repeattable track $index">     <td>         <table>             <tbody>                 <tr style="display: table-row">                     <th style="height: 46px;">                         <button type="button" role="button" ng-click="removeaddhockpis($index, table)">                             <span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>                         </button>                     </th>                 </tr>             </tbody>         </table>     </td> </table>

and remove button js code : 

$scope.removeaddhockpis = function (index, table) {     $scope.repeattable.splice(index, 1); };

when delete second table array, deleting last table (so "test3")

it deleted "test1" value , new array: enter image description here deleted table test3 (like photo enter image description here)

angular not deleting last element, it's deleting element wanted , updating $index bindings. array contains 3 elements; when remove second, third element becomes second , index value becomes 1 instead of 2, since have 2 elements in array.

check this fiddle. notice when click on remove input, correct person removed , indexes updated.
