为什么循环 While 不能正常工作？

Question

I have a loop that creates cards until the dealer's score is exactly 17. But there is a problem, it creates either exactly 17 or more.我有一个创建卡片的循环，直到庄家的分数恰好是 17。但是有一个问题，它创建的恰好是 17 或更多。 I tried to solve it by reloading the page, but I don't think it's the best solution.我试图通过重新加载页面来解决它，但我认为这不是最好的解决方案。 There is a dealer variable that stores points.有一个存储点数的经销商变量。 There are cards card A has a weight of 11, cards with the letters J, K, Q have a weight of 10, and cards on which a number is depicted have the same weight as the number itself.卡片 A 的权重为 11，带有字母 J、K、Q 的卡片的权重为 10，而上面描绘数字的卡片的权重与数字本身相同。 In the cycle, you need to collect cards until the dealer's points (dealer variable) becomes 17. And now I don't know how to stop the cycle when the points already exceed 17. Cards are selected randomly循环中需要收牌，直到庄家点数（dealer变量）变成17点，现在点数已经超过17点不知道怎么停止循环，随机抽牌

 let dealer = 0 let player = 0 let value = [2,3,4,5,6,7,8,9,10,'A','J','K','Q'] let type = ['ПИКИ','ТРЕФИ','ЧЕРВИ','БУБЕН'] let coloda = [] for (let index = 0; index < value.length; index++) { for (let i2 = 0; i2 < type.length; i2++) { coloda.push(value[index] + ' ' + type[i2]) } } coloda.sort(()=> Math.random() - 0.5) console.log(coloda) function start(){ while(dealer < 17){ let random = Math.floor(Math.random()* coloda.length) let addcard = document.createElement('div') addcard.classList.add('card') addcard.textContent = coloda[random] document.querySelector('.dealer').appendChild(addcard) sum(random) } if(dealer> 17){ //reload document.querySelector('.dl').textContent = dealer }else{ console.log('good') document.querySelector('.dl').textContent = dealer } } function sum(random){ let data = coloda[random].split('')[0] if(data == 'A'){ dealer = dealer + 11 } else if(data == 'J' || data == 'K' || data =='Q'){ dealer = dealer + 10 }else{ dealer = dealer + Number(data) } } start()

One thing you could do is check the value of the dealer every X seconds and proceed if it is above 17 like this (X should be a small number to make it act like a while loop)您可以做的一件事是每隔 X 秒检查一次经销商的价值，如果它像这样高于 17，则继续（X 应该是一个小数字，以使其像一个 while 循环）

function check() {
   if (dealer > 17) {
      return true
   } else {
      return false
   }
}

setInterval(function() {
   let valid = check();
   if (valid) {
      // Insert code here
   } else {
      console.log('Dealer is not above 17')
   }
}, X * 1000)
