多个按钮，每个按钮都有唯一的计数器

<button id="button1">按钮1</button>
<span id="counter1">0</span>

<button id="button2">按钮2</button>
<span id="counter2">0</span>

<!-- 添加更多按钮和计数器 -->

// 获取按钮和计数器元素
var button1 = document.getElementById("button1");
var counter1 = document.getElementById("counter1");

var button2 = document.getElementById("button2");
var counter2 = document.getElementById("counter2");

// 初始化计数器变量
var count1 = 0;
var count2 = 0;

// 按钮点击事件处理函数
button1.addEventListener("click", function() {
  count1++; // 增加计数器值
  counter1.textContent = count1; // 更新计数器显示
});

button2.addEventListener("click", function() {
  count2++; // 增加计数器值
  counter2.textContent = count2; // 更新计数器显示
});

// 添加更多按钮的事件处理逻辑
