累了休息一会儿吧——分享一个JavaScript版扫雷游戏

　　周末闲来无事写了一个JavaScript版扫雷游戏，现在把源代码分享出来，共同学习。

　　扫雷游戏的原理大家可以参考这篇文章：/article/5706381.html

　　JavaScript代码：

this.colCount = colCount || 10;//格子列数
this.landMineCount = 0;//地雷个数
this.markLandMineCount = 0;//标记的地雷个数
this.minLandMineCount = minLandMineCount || 10;//地雷最少个数
this.maxLandMineCount = maxLandMineCount || 20;//地雷最多个数
this.arrs = [];//格子对应的数组
this.beginTime = null;//游戏开始时间
this.endTime = null;//游戏结束时间
this.currentSetpCount = 0;//当前走的步数
this.endCallBack = null;//游戏结束时的回调函数
this.landMineCallBack = null;//标记为地雷时更新剩余地雷个数的回调函数
this.doc.oncontextmenu = function () {//禁用右键菜单
return false;

　　HTML部分：

<div id="FLM_main">
<table id="landmine">
</table>
<div id="operation">
<div class="tip">剩余雷数：<span class="light red" id="landMineCount">0</span></div>
<div class="tip">持续时间: <span class="light f60" id="costTime">0</span> s</div>
<input type="button" id="showLandMine" value="显示地雷" /><br />
<input type="button" id="showAll" value="显示全部" /><br />
<input type="button" id="begin" value="开始游戏" /><br />
<div class="tip txtleft">提示：
<ul>
<li>1、点击“开始游戏”游戏开始计时</li>
<li>2、游戏过程中点击“显示地雷”或“显示全部”游戏将会结束</li>
</ul>
</div>
</div>
</div>

　　调用部分：

window.onload = function () {
var flm = FLM("landmine", 10, 10),
doc = document,
landMineCountElement = doc.getElementById("landMineCount"),
timeShow = doc.getElementById("costTime"),
showLandMineButton = doc.getElementById("showLandMine"),
showAllButton = doc.getElementById("showAll"),
beginButton = doc.getElementById("begin"),
timeHandle = null;
flm.endCallBack = function () {
clearInterval(timeHandle);
};
flm.landMineCallBack = function (count) {
landMineCountElement.innerHTML = count;
};

//为“开始游戏”按钮绑定事件
beginButton.onclick = function () {
flm.play();//初始化

//显示地雷个数
landMineCountElement.innerHTML = flm.landMineCount;

//为“显示地址”按钮绑定事件
showLandMineButton.onclick = function () {
if (confirm("显示地雷游戏将结束？")) {
flm.failed();
flm.showLandMine();
}
};

//为“显示全部”按钮绑定事件
showAllButton.onclick = function () {
if (confirm("显示全部游戏将结束？")) {
flm.failed();
flm.showAll();
}
};

//开始
flm.begin();

//更新花费时间
timeHandle = setInterval(function () {
timeShow.innerHTML = parseInt((new Date() - flm.beginTime) / 1000);
}, 1000);
};
}

　　布局用的是table，所以FLM三个参数的第一个就是table的ID，第二个参数为最少地雷个数，第三个参数为最多地雷个数。

　　运行效果：

// (function () {

Demo

剩余雷数：0

提示：

1、点击“开始游戏”游戏开始计时

2、游戏过程中点击“显示地雷”或“显示全部”游戏将会结束
