JavaScript addition issue

Question

So, i'm adding 2 characters 4 levels together (hp, attack, strength and defense) and then comparing them. However I am having a problem. when the numbers are added together they're added together as a string so it outputs as follows. 9060951/99709940 instead of 246 (90+60+95+1)/308 (99+70+99+40). Here is what I am doing.

function calculate(player1, player2) {
 var total1 = player1.getTotal();
 var total2 = player2.getTotal();
 var differencePercentage;
 if(total1 > total2) {
 differencePercentage = total2 + "/" + total1 + " = " + (total2/total1);
 } else {
 differencePercentage = total1 + "/" + total2 + " = " + (total1/total2);
 }
 var percentage = differencePercentage;
 return percentage;
}
function Player(hp, attack, strength, defense) {
 this.hp = parseInt(hp);
 this.attack = parseInt(attack);
 this.strength = parseInt(strength);
 this.defense = parseInt(defense);
 this.getTotal = function() {
 var total = 0;
 total = hp + attack + strength + defense;
 return total;
 }
}

Why is this happening?

Answer 1

You are parsing the Ints into this.hp, this.attack etc. in your Player function but not into the getTotal function

Try this

this.getTotal = function() {
 var total = 0;
 total = this.hp + this.attack + this.strength + this.defense;
 return total;
}
