I am a beginner of AngularJS. I study the demo of ng-grid and have a question.

<body ng-controller="MyCtrl">
<div class="gridStyle" ng-grid="gridOptions"></div>
<div class="selectedItems">{{mySelections}}</div><br><br>
</body>
</html>
app.js
var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function($scope) {
$scope.mySelections = [];
$scope.myData = [{name: "Moroni", id: 1},
{name: "Tiancum", id: 2},
{name: "Jacob", id: 3},
{name: "Nephi", id: 4},
{name: "Akon", id: 5},
{name: "Enos", id: 6}];
$scope.gridOptions = {
data: 'myData',
selectedItems: $scope.mySelections,
multiSelect: true
};
//$scope.mySelections_id = $scope.mySelections.length;
});
When I select the first row, the div of selectedItems will show [{"name":"Moroni","id":1}]. the result is OK. If I just want to get the value of cell [id] from selected row, how do I modify my code?
here is Plunker

Use the afterSelectionChange callback to extract the ids from the selection to an other array.
$scope.gridOptions = {
data: 'myData',
selectedItems: $scope.mySelections,
multiSelect: true,
afterSelectionChange: function () {
$scope.selectedIDs = [];
angular.forEach($scope.mySelections, function ( item ) {
$scope.selectedIDs.push( item.id )
});
}
};
now you can reference {{selectedIDs}} from the template and has all the selected ids in it. Or just the first: {{selectedIDs[0]}}
See the working example here: http://plnkr.co/edit/xVwVWX

You can access the rowItem of the selected row with the arguments to the afterSelectionChange event. The entity property will have the id and name properties.
$scope.gridOptions = {
data: 'myData',
selectedItems: $scope.mySelections,
multiSelect: true,
afterSelectionChange: function (theRow, evt) {
alert(theRow.entity.id);
}
};
