POHow to access variables within another function

copied!<p>I'm writing code for a blackjack game and have run into some problems. I have written two functions: one for the initial deal and one for each consecutive hit. this is the deal function:</p> <pre><code>var deck = [1,2,3,4,5,6,7,8,9,10,"Jack","Queen","King","Ace"]; function deal() { var card1_val = Math.floor(Math.random() * deck.length); var card2_val = Math.floor(Math.random() * deck.length); var card1 = deck[card1_val]; var card2 = deck[card2_val]; var hand = card1 + ", " + card2; {//card1 Conditionals if (card1 == "Jack") { card1_val = 10; } else if (card1 == "Queen") { card1_val = 10; } else if (card1 == "King") { card1_val = 10; } else if (card1 == "Ace") { card1_val = 11; } } {//card2 Conditionals if (card2 == "Jack") { card2_val = 10; } else if (card2 == "Queen") { card2_val = 10; } else if (card2 == "King") { card2_val = 10; } else if (card2 == "Ace") { card2_val = 11; } } var res = card1_val + card2_val; document.getElementById("result").innerHTML = hand; //document.getElementById("test").innerHTML = card1_val + ", " + card2_val; if (res > 21) { alert("Blackjack!"); } } </code></pre> <p>This is the hit function:</p> <pre><code>function hit() { var card_val = Math.floor(Math.random() * deck.length); var nhand = deck[card_val]; bucket = hand + nhand } </code></pre> <p>If you look at hit() I am using the var hand from deal(). I can't make it global because I need the value to be a fresh random each time. How do I access this same variable without rewriting lines of code? Any help would be appreciated.</p>
