外面摆满了球，球上有字，拖动小球进入对应的框，如果答对则弹出对话框，写出相对应的代码

这个游戏的名称是“拖拽游戏”，下面是一个简单的实现，使用了HTML、CSS和JavaScript：

HTML代码：

<div class="container">
  <div class="box" id="box1"></div>
  <div class="box" id="box2"></div>
  <div class="box" id="box3"></div>
  <div class="ball" id="ball1" draggable="true">Apple</div>
  <div class="ball" id="ball2" draggable="true">Banana</div>
  <div class="ball" id="ball3" draggable="true">Orange</div>
</div>

CSS代码：

.container {
  width: 600px;
  height: 400px;
  border: 2px solid #000;
  position: relative;
}
.box {
  width: 100px;
  height: 100px;
  border: 2px solid #000;
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
}
#box1 {
  left: 10%;
}
#box2 {
  left: 40%;
}
#box3 {
  left: 70%;
}
.ball {
  width: 80px;
  height: 80px;
  border-radius: 50%;
  background-color: #999;
  color: #fff;
  text-align: center;
  line-height: 80px;
  position: absolute;
  cursor: move;
}

JavaScript代码：

var ball1 = document.getElementById("ball1");
var ball2 = document.getElementById("ball2");
var ball3 = document.getElementById("ball3");
var box1 = document.getElementById("box1");
var box2 = document.getElementById("box2");
var box3 = document.getElementById("box3");

ball1.addEventListener("dragstart", drag);
ball2.addEventListener("dragstart", drag);
ball3.addEventListener("dragstart", drag);

box1.addEventListener("dragover", allowDrop);
box2.addEventListener("dragover", allowDrop);
box3.addEventListener("dragover", allowDrop);

box1.addEventListener("drop", drop);
box2.addEventListener("drop", drop);
box3.addEventListener("drop", drop);

function drag(e) {
  e.dataTransfer.setData("text", e.target.id);
}

function allowDrop(e) {
  e.preventDefault();
}

function drop(e) {
  e.preventDefault();
  var data = e.dataTransfer.getData("text");
  var ball = document.getElementById(data);
  var box = e.target;
  if (box.id == "box1" && ball.innerHTML == "Apple") {
    alert("Correct!");
  } else if (box.id == "box2" && ball.innerHTML == "Banana") {
    alert("Correct!");
  } else if (box.id == "box3" && ball.innerHTML == "Orange") {
    alert("Correct!");
  } else {
    alert("Incorrect!");
  }
  box.appendChild(ball);
}

您可以将以上代码复制粘贴到HTML、CSS和JavaScript文件中，并在浏览器中打开HTML文件来运行游戏。
