<table class="table">

            <th> <input type='checkbox' name='selectall' ng-model="value1" ng-click="selectAll()"></th>
            <th>  Name </th>
        </thead>
        <tr ng-repeat="x in items">
            <td><input type='checkbox' ng-model="value2" ng-true-value="YES" ng-false-value="NO" ng-click="select($event,x.id)"

            <td>{{x.name}}</td>
            </tr>
        </tr>
    </table>

How to I get all the item.id when I click "selectall()" checkbox ?

Also, Can you suggest me appropriate ng-model syntax for ng-repeat checkbox ?

Thanks,Raja K

解决方案

var myapp = angular.module('app', []);
myapp.controller('Ctrl', function ($scope) {
  var vm = this;
    vm.data = {
      items: [
         {id:1,name:"ali",selected: "NO"},
         {id:2,name:"reza",selected: "NO"},
         {id:3,name:"amir",selected: "NO"}
      ]
     };

  vm.value1 = false;

  vm.selectAll = function($event){
     var checkbox = $event.target;
     var selected = "NO";
         if(checkbox.checked)
           {
           selected = "YES";
           }
    else {
      selected = "NO";
      }
    angular.forEach(vm.data.items, function(item) {
             item.selected = selected;
             });




    }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="Ctrl as vm">
<table class="table">
<thead>
            <th> <input type='checkbox' name='selectall' ng-model="value1" ng-click="vm.selectAll($event)"></th>
            <th>  All </th>
        </thead>
        <tr ng-repeat="x in vm.data.items">
            <td><input type='checkbox' ng-model="vm.data.items[$index].selected" ng-true-value="YES" ng-false-value="NO" ng-click="vm.select($event,x.id)"
                            /></td>
            <td>{{x.name}}</td>

        </tr>
    </table>
