passing the data in $scope variable

Question

I am getting the data from my web service and storing the same data into my scope variable like

then(function (Tlist) {
                    $scope.Tlist=Tlist.data;
                })

and displaying the same data into table, now in my table i am selecting the row by checkbox like

                    <td>
                        <input type="checkbox" ng-checked="checkall" ng-model="Ldata.checked" data-ng-click="calculateTotal(Ldata)" />
                    </td>

and in my "calculateTotal(Ldata)" function i want to store the value of (Ldata.amount) into another $scope variable

this is how my condition inside the function looks

        if (Ldata.checked) {
            $scope.total += Number(Ldata.amount);
            console.log(Ldata.amount);
            console.log(Number($scope.total));
        }

but on

console.log(Number($scope.total));

line my result is coming as NaN but on this line and on console.log(Ldata.amount); this line my result is coming as 1400 so i am not able to understand why i am unable to pass data from one variable to another

it's not really clear what you are asking here. what does the first code snippet have to do with the rest of the question? What is in $scope.total when you start here? What does console.log($scope.total); output? It seems like $scope.total isn't a legal number... — Claies

The title of the question is misleading, since this doesn't really appear to have anything at all to do with "passing the data in $scope variable"..... — Claies

please edit your question and be more specific so that we can go through solution. — Anil Shrestha

You receive NaN probably because the $scope.total is undefined. If you really want to use += operator you need to know two things:

a += b is a shortcut of a = a + b
any math operation on number value and undefined will return NaN value

Just set the initial value to $scope.total - for example at the beginning of your controller definition set $scope.total = 0;.

Instead of Number use parseInt

 console.log(parseInt($scope.total));
