每次触发滚动骰子单击并从随机数学函数生成新的数字时，尝试从数据集中添加骰子滚动值。

当前，值被添加到数组中，但是只添加了一个值，并且数组不会随着每个新的滚动值而增加。

将每个新值推送到数组的最佳方法是什么？包括最多增加25项。

目标是首先对每个骰子滚动值进行控制台日志记录，然后在html中将其显示为包含25个滚动结果的列表。

代码如下：

function rollDice() {
    const dice = [...document.querySelectorAll(".die-list")];
    dice.forEach(die => {
      toggleClasses(die);
      die.dataset.roll = getRandomNumber(1, 6);
      let res1 = document.getElementById("die-1").dataset.roll;
      let res2 = document.getElementById("die-2").dataset.roll;
      let res1Num = parseInt(res1);
    
      let resConten1 = document.getElementById("result1");
      let resConten2 = document.getElementById("result2");
      resConten1.innerHTML = res1;
      resConten2.innerHTML = res2;
      
      // Results Array 
      let res1Arr = [];
      console.log(res1Arr);
  
       if (res1Num < 25 ) {      
        res1Arr.push(res1Num);
        console.log(res1Arr);
        } 
  
    });
  
  }
  
  function toggleClasses(die) {
    die.classList.toggle("odd-roll");
    die.classList.toggle("even-roll");
  }
  
  function getRandomNumber(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
  }
  
  
  document.getElementById("roll-button").addEventListener("click", rollDice);

您应该将let res1Arr = []放在函数之外，因为它现在在每个函数调用中返回到空数组。另外，为了避免在每个函数调用上数组中出现双重结果，您应该将array.push放在forEach循环之外，因为它对每个调用迭代两次。
