Menu
I am new to angular js, I have an array I am looping it through ng-repeat directive, and I have written code for copy, remove, and edit values in the array.
If I want to remove or copy I can do it, done? But if I click on edit one popup box will appear there I want to edit the values those updated values should update in the array.
How can I get it done?

The easiest way is to use angular.copy to create a clone of the object when edit is clicked and then when save is clicked copy the data to the item in the array.
First initilize $scope.editedItem
$scope.editedItem = {};
For editrow we store the currently edited index in $index and then clone the data into $scope.editedItem.
$scope.editrow = function($index){
$scope.istrue = true;
$scope.$index = $index;
angular.copy($scope.items[$index], $scope.editedItem);
}
Then in save we clone the data back into the object in the array:
$scope.save = function(){
$scope.istrue = false;
angular.copy($scope.editedItem, $scope.items[$scope.$index])
}
The view needs to be updated to instead use editedItem:
<div class="editpopup editpopup-{{istrue}} ">
<p>edit id:<input type="text" ng-model="editedItem.id"></p>
<p>edit pname:<input type="text" ng-model="editedItem.pname"></p>
<button ng-click="save()">save</button>
<button ng-click="closepopup()">cancel</button>
</div>
