Tried with splice function, but not able to delete all items from the first table.

Answer 1

This will clear your array and push all entries in $scope.merged

$scope.pushlist = function(data){ for(var item of data){ $scope.merged.push({"name":item.name}); } data.length=0 }; 

Answer 2

Use angular.copy to make an copy of the object

var app = angular.module("myApp", []); app.controller("SecondCtrl", function($scope) { $scope.merged = []; $scope.data = [{ "name": "ABC", "selected": false }, { "name": "HJK", "selected": false }, { "name": "PQR", "selected": false }, { "name": "LMN", "selected": false }]; $scope.selectall = function(checkAll) { if (checkAll) { $scope.merged = angular.copy($scope.data); $scope.data.length = 0; } else { $scope.data = angular.copy($scope.merged); $scope.merged.length = 0; } }; });

<script src="http://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.js"></script> <div ng-app="myApp" ng-controller="SecondCtrl"> <div> <h1>Old Table</h1> <table> <thead> <th> <input type="checkbox" ng-click="selectall(checkAll)" ng-model="checkAll">Select All</th> <th>Name</th> </thead> <tbody> <tr ng-repeat="item in data"> <td> <input type="checkbox" ng-model="item.selected"> </td> <td>{{item.name}}</td> </tr> </tbody> </table> </div> <hr> <div> <h2>New Table</h2> <table ng-show="merged"> <thead> <th>Name</th> </thead> <tbody> <tr ng-repeat="item in merged"> <td>{{item.name}}</td> </tr> </tbody> </table> </div> </div>
