修改这段代码，使一个兔子在跳跃时，不在对该兔子调用randomBunny函数

以下是修改后的代码：

var jumptimer;

function bunnyjump(jumpingbunnyId) {
  var id = "bunny" + jumpingbunnyId;
  var count = 1;
  var offset = 10;
  var direction = "up";
  
  // 停止随机选择兔子跳跃的定时器
  clearInterval(randomevent);
  
  jumptimer = setInterval(function() {
    var bunny = document.getElementById(id);
    
    if (count == 21) {
      direction = "down";
    } else if (count == 0) {
      direction = "up";
    }
    
    if (direction == "up") {
      count++;
    } else if (direction == "down") {
      count--;
    }
    
    bunny.style.bottom = count * offset + "px";
  }, 70);
  
  bunny.jumpevent = setInterval(function() {
    var bunny = document.getElementById(id);
    
    if (count == 21) {
      direction = "down";
    } else if (count == 0) {
      direction = "up";
    }
    
    if (direction == "up") {
      count++;
    } else if (direction == "down") {
      count--;
    }
    
    bunny.style.bottom = count * offset + "px";
  }, 70);
}

function kill(bunny) {
  var id_str = bunny.id;
  var id = parseInt(id_str[id_str.length - 1]);
  var blinksrc = "img/" + bunny.id + "-blink.png";
  
  bunny.style.backgroundImage = "url(" + blinksrc + ")";
  
  setTimeout(function() {
    clearInterval(bunny.jumpevent);
    bunny.jumpevent = null;
    bunny.style.display = "none";
    
    // 重新启动随机选择兔子跳跃的定时器
    randomevent = setInterval(function() {
      randomBunny();
    }, 1000);
  }, 200);
}

var bunnies = 5;
var randomevent = null;

function randomBunny() {
  var random = Math.ceil(Math.random() * bunnies);
  bunnyjump(random);
}

// 初始时启动随机选择兔子跳跃的定时器
randomevent = setInterval(function() {
  randomBunny();
}, 1000);

修改后的代码在 `bunnyjump` 函数中，添加了一行 `clearInterval(randomevent);`，该行代码会停止随机选择兔子跳跃的定时器。在 `kill` 函数中，添加了一行 `randomevent = setInterval(function() { randomBunny(); }, 1000);`，该行代码会重新启动随机选择兔子跳跃的定时器。这样，当一个兔子在跳跃时，不会再次被随机选择并跳跃。
