Anonymous Function prints as string

Question

In Javascript, I wanted to calculate total of two variables received from textbox, let us say txtBoxA and txtBoxB. The value gets calculated in an anonymous function and is stored in a variable total. Please take a look at the following code to see how it is calculated:

var total = function () {
            var total = parseFloat(txtbox[1].value) + parseFloat(txtbox[2].value);
            if (total == NaN) return 0;
            else return total;
        };
        alert(total);

but unfortunately, the anonymous function itself is printed as it is as shown in the image below.

alert(total);

You are just printing the function variable. If you want to execute it, you have to add (), so that it calls.

 alert(total());

And that is not an anonymous function. Just a function declaration and assigning to a variable.
