老虎机游戏

没有将数字放在对的位置 需要在改进

<script>
  function runSlots() {
    var slotOne;
    var slotTwo;
    var slotThree;
    
    var images = ["//i.imgur.com/9H17QFk.png", "//i.imgur.com/9RmpXTy.png", "//i.imgur.com/VJnmtt5.png"];

    //产生1-3的数字
    slotOne = Math.floor(Math.random() * (3 - 1 + 1)) + 1;
    slotTwo = Math.floor(Math.random() * (3 - 1 + 1)) + 1;
    slotThree = Math.floor(Math.random() * (3 - 1 + 1)) + 1;


   //让我们用 jQuery 选择器 $(".slot") 获得所有老虎机；
   //一旦获取到所有老虎机，我们可以通过中括号操作符获取到每一个老虎机；
   //jQuery将会获取到第一个老虎机，并更新它的HTML为正确的数字。
    $($(".slot")[0]).html(slotOne);　
    $($(".slot")[1]).html(slotTwo);
    $($(".slot")[2]).html(slotThree);
    //设置所有的老虎机根据随机数来显示对应的图片，最后点击RUN。
    $($('.slot')[0]).html('<img src = "' + images[slotOne-1] + '">');
    $($('.slot')[1]).html('<img src = "' + images[slotTwo-1] + '">');
    $($('.slot')[2]).html('<img src = "' + images[slotThree-1] + '">');

    if (slotOne === slotTwo && slotTwo === slotThree) {
      $(".logger").html(" It's A Win")
      return null;
    }
    
    if (slotOne !== undefined && slotTwo !== undefined && slotThree !== undefined){
      $(".logger").html(slotOne + " " + slotTwo + " " + slotThree);
    }
