I am using ng-repeat and rendering the data into table

<tbody>
  <tr ng-repeat="datas in data" >
   <td ng-repeat="d in datas">
    {{d}}
   </td>
   <td>
    <button class="btn btn-primary" ng-click="close(d)">Close</button>
   </td>
  </tr>
  </tbody>

I want button in all the rows which can able to close that particular instance but how to do it ? in json we can do with key. How can I do it here ?

Answer 1

If you need a unique key to close the row by it. Then you can use

<tr ng-repeat="(key, value) in data">

so the key will point to the index of the array 0, 1, 2, ...

Answer 2

You only need to pass the ec2 instance ID which is d[0]

<button class="btn btn-primary" ng-click="close(d[0])">Close</button>

and your close function would be like

$scope.close = function(id) {
   // factory send ajax to close the instance ... then
   let index = $scope.data.findIndex((i)=> i[0]===id)
   $scope.data.splice(index,1); // this would remove the item from your table
}
