我正在尝试编写一个简单的tic-tac toe游戏,但我遇到了两件事的问题:
我的3x3电路板没有分成不同的行 - 当我尝试制作更多游戏磁贴时,它只是将它放在同一行
我可以通过复制底部的代码来创建新的X和O图像,但我不知道如何在播放后将它们锁定到位。
这是我目前的HTML:
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
#div1 {
width: 80px;
height: 80px;
padding: 10px;
border: 1px solid #aaaaaa;
float:left;
}
</style>
<script type="text/javascript">
function allowDrop(ev) {
ev.preventDefault();
}
function drag(ev) {
ev.dataTransfer.setData("Text",ev.target.id);
}
function drop(ev) {
var data=ev.dataTransfer.getData("Text");
ev.target.appendChild(document.getElementById(data));
ev.preventDefault();
}
</script>
<title>JavaScript Drag & Drop Tic-Tac-Toe</title>
</head>
<body>
<p>Drag the X and O images into the tic-tac-toe board:</p>
<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<img id="drag1" src="X.png" draggable="true"
ondragstart="drag(event)" width="75" height="75" />
<img id="drag2" src="O.png" draggable="true"
ondragstart="drag(event)" width="75" height="75" />
</body>
</html>
答案 0 :(得分:1)
你不能给每个div赋予相同的id,id必须对每个div都是唯一的。你必须在id的地方上课。我们可以为许多div提供相同的类名。你可以尝试这段代码。
