以下是不使用JSON的方法：

// Function to save high score
function saveHighScore() {
  let date = new Date();
  let highScoreDiv = document.getElementById("highScoreDiv"); // Assuming you have a div with the id "highScoreDiv"
  let highScoreNumbers = `Your high score is ${pikmin.numberOf} on ${date}!`;

  let highScoreDivNew = document.createElement("div");
  highScoreDivNew.textContent = highScoreNumbers; // Use textContent to set the text of the new div

  highScoreDiv.appendChild(highScoreDivNew);
  localStorage.setItem("highScoreContent", highScoreNumbers); // Store the high score directly as a string
}

// Function to load and display high score from localStorage
function loadHighScore() {
  let highScoreDiv = document.getElementById("highScoreDiv");
  let highScoreNumbers = localStorage.getItem("highScoreContent"); // Retrieve the high score as a string
  if (highScoreNumbers) {
    let highScoreDivNew = document.createElement("div");
    highScoreDivNew.textContent = highScoreNumbers; // Use textContent to set the text of the new div
    highScoreDiv.appendChild(highScoreDivNew);
  }
}

appendChild（）方法将指定的元素作为元素的子元素追加。我为造成的混乱道歉。
要将高分附加到body中的特定div中，需要以该div为目标，然后使用appendChild（）方法将新的高分元素附加为该div的子元素。
假设你的HTML中有一个id为“highScoreDiv”的div，你想在其中显示高分，你可以这样修改saveHighScore（）函数：

// Function to save high score
function saveHighScore() {
  let date = new Date();
  let highScoreDiv = document.getElementById("highScoreDiv"); // Assuming you have a div with the id "highScoreDiv"
  let highScoreNumbers = `Your high score is ${pikmin.numberOf} on ${date}!`;

  let highScoreDivNew = document.createElement("div");
  highScoreDivNew.textContent = highScoreNumbers; // Use textContent to set the text of the new div

  highScoreDiv.appendChild(highScoreDivNew);
  // localStorage.setItem("highScoreContent", highScoreNumbers); // Don't save as a string
  // Instead, let's store the high scores in an array:
  let highScores = JSON.parse(localStorage.getItem("highScores") || "[]"); // Retrieve existing scores or an empty array
  highScores.push(highScoreNumbers); // Add the new score to the array
  localStorage.setItem("highScores", JSON.stringify(highScores)); // Store the updated array as a string
}

确保你的HTML中有一个id为“highScoreDiv”的div，你想在这里显示高分。如果div不存在，你需要像这样在HTML中添加它：

<div id="highScoreDiv"></div>
