简易五子棋判断及棋盘制作

© BaiG 2022. All rights reserved.

整体思路：

首先先使用 JavaScript 生成 15*15 棋盘
按下后生成棋子
每次生成棋子后判断：棋子是否连续5颗

代码+制作过程：

var ended = false;
// 用来判断是否可以继续放下棋子
var zi = 0;
// 棋盘上有的棋子数量
var color = 'black';
// 当前下棋方颜色 ['black' / 'white;]
var colorNum = 1;
// 颜色号码 [1 / 2]
var qipan = $('#qipan');
// 获取要生成棋盘的 div

<div class="center" id="qipan">
</div>
<div class="infor">
    <h1 id="xiaqifang">当前下棋方：黑子</h1>
    <h1 id="dinkezi">第0颗子</h1>
</div>

// make 15*button.col_btn 15 * div.raw
for (var i = 0; i < 15; i++) { // 15 横行
    var raw = $('<div class="raw"></div>');
    for (var j = 0; j < 15; j++) { // 15 纵行
        var col_btn = $('<button class="col_btn"></button>');
        col_btn.attr('id', i + '-' + j);
        col_btn.attr('onclick', 'chess(this)');
        raw.append(col_btn);
        /* 在每个纵行上生成按钮
           class 是 col_btn
           id 是 y坐标-x坐标
           同时生成 onclick 事件
           按下时触发函数：chess 并将元素作为参数传入
           ( chess(element) )
        */
    }
    qipan.append(raw);
}

var chess_arr = [

输赢判断：

(arr[i][j] == 1) && (arr[i][j] == arr[i][j + 1])

arr[i][j] == 1 判断是否是黑子
arr[i][j] == arr[i][j + 1] 判断下一格和自己是不是一样的

// 纵向

        } else if ((arr[i][j] == 2) && (arr[i][j] == arr[i + 1][j])) {
            count_white++;
        }
        if (count_black == 4) {

这样算赢。。。

(arr[i][j] == 1) && (arr[i][j] == arr[i][j + 1]) 变成：

(arr[i][j] == 1) && (arr[i][j] == arr[i][j + 1]) && (arr[i][j] == arr[i][j + 2]) && (arr[i][j] == arr[i][j + 3]) && (arr[i][j] == arr[i][j + 4])

这样的话就不会发生刚刚的情况了

其他几个也是一样的改改

function win(arr) {
    var count_black = 0;
    var count_white = 0;
    // 横向
    for (var i = 0; i < 15; i++) {

            if ((arr[i][j] == 1) && (arr[i][j] == arr[i][j + 1]) && (arr[i][j] == arr[i][j + 2]) && (arr[i][j] == arr[i][j + 3]) && (arr[i][j] == arr[i][j + 4])) {
                count_black++;
            } else if ((arr[i][j] == 2) && (arr[i][j] == arr[i][j + 1]) && (arr[i][j] == arr[i][j + 2]) && (arr[i][j] == arr[i][j + 3]) && (arr[i][j] == arr[i][j + 4])) {
                count_white++;

            if (count_black == 4) {

                return true;
            } else if (count_white == 4) {
                end('白子赢了');
                return true;
            }
        }
    }
    count_black = 0;
    count_white = 0;
    // 纵向
    for (var i = 0; i < 15; i++) {

                count_white++;
            }
            if (count_black == 4) {
                end('黑子赢了');
                return true;
            } else if (count_white == 4) {
                end('白子赢了');
                return true;
            }
        }
    }
    count_black = 0;
    count_white = 0;
    // 斜向
    for (var i = 0; i < 15; i++) {

                count_black++;
            } else if ((arr[i][j] == 2) && (arr[i][j] == arr[i + 1][j + 1]) && (arr[i][j] == arr[i + 2][j + 2]) && (arr[i][j] == arr[i + 3][j + 3]) && (arr[i][j] == arr[i + 4][j + 4])) {
                count_white++;
            }
            if (count_black == 4) {
                end('黑子赢了');
                return true;
            } else if (count_white == 4) {
                end('白子赢了');
                return true;
            }
        }
    }

            if ((arr[i][j] == 1) && (arr[i][j] == arr[i - 1][j + 1])) {

            } else if ((arr[i][j] == 2) && (arr[i][j] == arr[i - 1][j + 1])) {

            }
            if (count_black == 4) {
                end('黑子赢了');
                return true;
            } else if (count_white == 4) {
                end('白子赢了');
                return true;
            }
        }
    }
    count_black = 0;
    count_white = 0;
}

这就变正常了
