Part 2 : Simple list example Add/Edit and Delete with Angular

In this tutorial, we will learn add, edit and delete functionality into angularjs application.We will add functionality of add record, edit record and delete record on grid listing.Angular provide very simple logic on behind add/edit and delete functionality, If you have knowledge of JSON object/Array then you can do it with in minute, you learn within five minute to add/edit and delete functionality on angular.

Step 1: We will add add,edit and delete icon on table list.I am using bootstrap3 lib so here i am using class of bootstrap.

<div class="btn-group">
                <button type="button" class="btn btn-default btn"><i class="glyphicon glyphicon-pencil"></i></button>  
                <button type="button" class="btn btn-default btn"><i class="glyphicon glyphicon-trash"></i></button> 
</div>

Step 2: Now We will create add,edit and delete function in controller.

$scope.edit = function(id) {
		   //search user and update it
		    $scope.objectIndex = id;
			$scope.userObject = angular.copy($scope.userList[id]);
			console.log($scope.objectIndex);
		}
		
		$scope.save = function() {
			console.log($scope.objectIndex);
			if($scope.userList[$scope.objectIndex] == null) {
				//this is new record
				$scope.userList.push($scope.userObject);
			} else {
				//for existing record
				//and update it.
					$scope.userList[$scope.objectIndex] = $scope.userObject;               
			}
			 
			//clear the add record form
			$scope.userObject = {};
			$scope.objectIndex = '';
		}
		
		$scope.delete = function(id) {
			//search record with given id and delete it
			for(i in $scope.userList) {
				if($scope.userList[i].id == id) {
					$scope.userList.splice(i,1);
					$scope.newcontact = {};
				}
			}
			 
		}

Step 3: Now we will call these method on click of icon on table list.

<div class="btn-group">
                <button type="button" class="btn btn-default btn" ng-click="edit($index);"><i class="glyphicon glyphicon-pencil"></i></button>  
                <button type="button" class="btn btn-default btn" ng-click="delete();"><i class="glyphicon glyphicon-trash"></i></button> 
</div>
