AngularJS, calculation addition (+) is not working

I tried to calculate $scope values through angular controller. For instance: the below code works in order to multiply values inside brackets. However, addition(+) is working like 400+200 = 400200. How to get output 600?

   $scope.output = ($scope.quantity.Quantity * $scope.pro_price) + $scope.wait_price;
Solution

  • You need to parse the variable, since your scope variable might be of type string,

    $scope.output = ($scope.quantity.Quantity * $scope.pro_price) + parseInt($scope.wait_price);
