我正在写一个井字游戏程序。到目前为止,我具有3x3网格,并且能够将X和O图像拖放到网格中。

要宣布获胜者,我是否要使用if else语句?

我只是想知道如何宣布获胜者。我猜想这需要JavaScript。

这是我在jsfiddle中的代码,以及下面的编译代码:

http://jsfiddle.net/VXQ7P/


<!DOCTYPE HTML>
<html>
<head>

<style type="text/css">

  #div1, #div2, #div3, #div4, #div5, #div6, #div7, #div8, #div9 {
      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);
        helper:clone;
    }

    function drop(ev) {
        var data=ev.dataTransfer.getData("Text");
        ev.target.appendChild(document.getElementById(data).cloneNode(true));
        ev.preventDefault();
    }
</script>

<title>JavaScript  Drag &amp; Drop Tic-Tac-Toe</title>
</head>

<body>
    <p>Drag the X and O images into the tic-tac-toe board:</p>

    <table>
        <tr>
            <td><div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
            <td><div id="div2" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
            <td><div id="div3" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
        </tr>
        <tr>
            <td><div id="div4" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
            <td><div id="div5" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
            <td><div id="div6" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
        </tr>
        <tr>
            <td><div id="div7" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
            <td><div id="div8" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
            <td><div id="div9" ondrop="drop(event)" ondragover="allowDrop(event)"></div></td>
        </tr>
    </table>

    <img id="drag1" src="X.png" ondragstart="drag(event)" width="75" height="75"/>
    <img id="drag2" src="O.png" draggable="true" ondragstart="drag(event)" width="75" height="75"/>
</body>
</html>

最佳答案

在我的选择下,你到那儿去了。您应该为每个字段使用“ onclick()”,然后将div的innerhtml更改为X或O。您可能还想在Google上搜索“ tic tac toe javascript”。很多人以前都这样做过。例如查看以下内容:http://jsfiddle.net/rtoal/ThPEH/
获胜者的定义方式非常容易理解,并且在那里得到了很好的解释。 ;)
从网站获得:

/*
 * To determine a win condition, each square is "tagged" from left
 * to right, top to bottom, with successive powers of 2.  Each cell
 * thus represents an individual bit in a 9-bit string, and a
 * player's squares at any given time can be represented as a
 * unique 9-bit value. A winner can thus be easily determined by
 * checking whether the player's current 9 bits have covered any
 * of the eight "three-in-a-row" combinations.
 *
 *     273                 84
 *        \               /
 *          1 |   2 |   4  = 7
 *       -----+-----+-----
 *          8 |  16 |  32  = 56
 *       -----+-----+-----
 *         64 | 128 | 256  = 448
 *       =================
 *         73   146   292
 *
 */
wins = [7, 56, 448, 73, 146, 292, 273, 84],


编辑:
您可以将每个TicTacToe单元的状态和值存储在数组中。这样,您可以轻松地访问他们以确定是否有赢家。
