how to print a value from function in angularjs

Question

Have a look at the code in images below:

HTML:

JS:

cartAmt = productDetail.discountedPrice++; this is not working

${{cart.cartAmt}} this value is not shown up

Answer 1

In your code cartAmt is a global variable, add it to scope.

// Set cart amount to zero initially
$scope.cartAmt = 0    


$scope.cart= function(){   
    $scope.cartAmt += $scope.event.productDetail.discountedPrice; 
}

And in your HTML, you can access it like this:

<ins>cartAmt</ins>

Also as I mentioned in comments, following line has a logical error.

$scope.cartAmt = $scope.event.productDetail.discountedPrice++; 

You should use:

$scope.cartAmt += +$scope.event.productDetail.discountedPrice;
