Question

我正在创建一个简单的二十一点游戏，但是我在最后一步遇到了一个问题，我创建了一个if语句来决定用户支付胜利是否吸引，它似乎只执行声明中的第一个条件当按下支架按钮时，无论用户是赢还是输，它都会显示"you win"。

    <h1><i>BLACKJACK</i></h1>
    <h4>

      <br>Player 1 cards: <input type="text" id="playerscards">

  </head>

  <input type="button" value="start" onclick="document.getElementById('playerscards').value = random()">

  <input type="button" value="deal" onclick="dealcard()">

  <input type="button" value="stand" onclick="keepcards()">

  <input type="button" value="new game" onclick="window.location.reload()">

  <p>To start the game press start and draw a card<br> Press deal to add a new card <br> press stand if you do not wish to draw a new card<br> Prsee new game if you want to refresh the page to play a mew game</p>

<script src="java.js"></script>

javascript

var randomnumber = Math.floor(Math.random() * 10 + 1);

function random() {
  return randomnumber;
}

var total = randomnumber;

function dealcard() {
  total += Math.floor(Math.random() * 10 + 1);
  document.getElementById('playerscards').value = total;

  if (total > 21) {
    alert("You have gone bust click new game to play again!");
  }
}

function keepcards() {
  if (total > randomnumber) {
    alert("You win!");
  } else if (total < randomnumber) {
    alert("You lose!");
  } else if (total == randomnumber) {
    alert("It is a draw!");
  }
}

now = new Date();
localtime = now.toString();

hours = now.getHours();
mins = now.getMinutes();
secs = now.getSeconds();
document.write("<h1>");
document.write(hours + ":" + mins + ":" + secs);
document.write("</h1>");

if语句仅应用第一个条件
