    hello

    I need some help here..

    i have this json file:

    {
"col": [
     {
          "rec": {
               "id":"0001",
               "name":"name1",
               "loc": [
                    {"name":"cal", "nb":350},     <--- i want this number
                    {"name": "fat", "nb":100}]
          }
     },
     {
          "rec": {
               "id":"0002",
               "name": "name2",
               "loc": [
                    {"name":"cal", "nb":650},     <--- i want this number
                    {"name": "fat", "nb":100}]
          }
     }
]}


    I want to plus all the cal - nb numbers from my json file.
    like this: 350 + 650 = 1000

    i have this function. but i can not get this to work correctly. my totalcount just stay at 0 all the time.

    app.controller('appCtrl', function($scope) {
   
    $scope.totalCount = function() {

        var count = 0;
        angular.forEach($scope.data, function(value, key) {
             count = count + value.col.rec.loc[0].nb;
        });
        return count;
    }

});


    can someone help me make this work?  thanks :-)

    Hi kkooaa,

    The following sample code works fine on my side, please refer to it.

    <input data-ng-click="totalCount()" type="button" value="click me" />
    $scope.totalCount = function () {
    var count = 0;
    for (var i = 0; i < $scope.data.col.length; i++) {
        count = count + $scope.data.col[i].rec.loc[0].nb;
    }
    alert(count);
    //return count;

}

    Best Regards,

    Fei Han
