NG-變化增量和NG-repeat循環

decreament值我有這樣的代碼：NG-變化增量和NG-repeat循環

      <div class="container"> 
 
       <div class="col-md-3 well"> 
 
        Are you developer <input type="checkbox" ng-model="isTrue" ng-change="count=count+1" /> 
 
        Count: {{count}} 
 
        <pre>{{isTrue}}</pre> 
 
       </div> 
 
      </div> 
 
     </div> 
 
     <script> 
 
     var app = angular.module("changeExample", []); 
 
     app.controller('ExampleController', ['$scope', function ($scope) { 
 
      $scope.isTrue = true; 
 
     }]); 
 
    </script> 
 
    </body> 
 
    </html>

在這段代碼時選中的複選框的數量會增加。這裏如何檢查複選框是否勾選，然後只增加，否則如果不勾選，它會減少。請任何人幫忙。

嘗試'NG-變化= 「IsTrue運算（計數=計數+ 1）：（數=計-1）' –

那麼什麼是你的這個要求呢？」我有多個ng-repeat循環中的複選框「 – Nitheesh

嘗試改變NG-變化。

我在ng-repeat循環中有多個複選框 – SARAN

您可以使用模型值作爲ng-repeat屬性並將該屬性傳遞給同一個函數。不是一個好的編碼程序。 – Nitheesh
