I need a Sum of Balance from the Following Data in HTML not in JS Controller Function. So, I used the ng-init within the ng-repeat. But I can't able to get the result.

My JSON Data is

{
   "records":[
      {
         "ldat":"2014-08-13",
         "eid":"HSL018",
         "dr":"55420",
         "cr":"0",
         "bal":"55420"
      },
      {
         "ldat":"2014-10-11",
         "eid":"HBL056",
         "dr":"0",
         "cr":"35000",
         "bal":"20420"
      },
      {
         "ldat":"2014-10-26",
         "eid":"HBL001",
         "dr":"0",
         "cr":"420",
         "bal":"20000"
      },
      {
         "ldat":"2015-11-01",
         "eid":"HDL001",
         "dr":"0",
         "cr":"20000",
         "bal":"0"
      }
   ]
}

My HTML is

<h3>Net Balance {{ legTot }}</h3>
<table class="table table-striped table-bordered">
  <thead>
    <tr>
      <td class="text-center">#</td>
      <td class="text-center">Last Trans</td>
      <td class="text-center">Dr</td>
      <td class="text-center">Cr</td>
      <td class="text-center">Balance</td>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="x in data | orderBy:'eid' | orderBy:orderByField:reverseSort">
      <td>{{ $index + 1 | number }}</td>
      <td class="text-center">{{ x.ldat }}</td>
      <td class="text-right">{{ x.dr | currency:"&#8377;" }}</td>
      <td class="text-right">{{ x.cr | currency:"&#8377;" }}</td>
      <td class="text-right" ng-init="legTot = legTot + x.bal | number">{{ x.bal | currency:"&#8377;" }}</td>
    </tr>
  </tbody>
</table>

Here I used the ng-init="legTot = legTot + x.bal | number" to sum the balance legTot is a Scope Variable.

I Can't able to get the total. Kindly assist me how to achieve this without foreach loop in AngularJS Controller Function.

• javascript
• angularjs
• angularjs-ng-repeat
• angularjs-ng-init
• ng-init

• I believe ng-init should be on the same element as ng-repeat – sg Commented Feb 10, 2016 at 1:39
• There are only a few appropriate uses of ngInit, such as for aliasing special properties of ngRepeat; and for injecting data via server side scripting. Besides these few cases, you should use controllers rather than ngInit to initialize values on a scope. – georgeawg Commented Feb 10, 2016 at 2:12
• you aren't accounting for child scopes created by ng-repeat. This needs to be done in controller – charlietfl Commented Feb 10, 2016 at 2:37

ng-init creates new child scope. To inherit scope variables from parent to child, you should put those variable to an object. In your scope in controller, create object with name 'vm' and put your 'legTot' variable inside it.

$scope.vm = {legTot: 0}

And change html

<h3>Net Balance {{ vm.legTot }}</h3>
<table class="table table-striped table-bordered">
  <thead>
    <tr>
      <td class="text-center">#</td>
      <td class="text-center">Last Trans</td>
      <td class="text-center">Dr</td>
      <td class="text-center">Cr</td>
      <td class="text-center">Balance</td>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="x in data | orderBy:'eid' | orderBy:orderByField:reverseSort">
      <td>{{ $index + 1 | number }}</td>
      <td class="text-center">{{ x.ldat }}</td>
      <td class="text-right">{{ x.dr | currency:"&#8377;" }}</td>
      <td class="text-right">{{ x.cr | currency:"&#8377;" }}</td>
      <td class="text-right" ng-init="vm.legTot = vm.legTot + Number(x.bal)">{{ x.bal | currency:"&#8377;" }}</td>
    </tr>
  </tbody>
</table>

Solution without forEach loop jsfiddle.

var myApp = angular.module("myApp", []);

myApp.controller("myCtrl", function($scope) {
  $scope.legTot = 0;
  $scope.addBal = function(bal){
    $scope.legTot+=bal;
  }
  $scope.data = [{
    "ldat": "2014-08-13",
    "eid": "HSL018",
    "dr": "55420",
    "cr": "0",
    "bal": "55420"
  }, {
    "ldat": "2014-10-11",
    "eid": "HBL056",
    "dr": "0",
    "cr": "35000",
    "bal": "20420"
  }, {
    "ldat": "2014-10-26",
    "eid": "HBL001",
    "dr": "0",
    "cr": "420",
    "bal": "20000"
  }, {
    "ldat": "2015-11-01",
    "eid": "HDL001",
    "dr": "0",
    "cr": "20000",
    "bal": "0"
  }];
});

<body ng-app="myApp" ng-controller="myCtrl">

      </tr>
