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：http://www.cnblogs.com/goodwin/archive/2010/03/22/1691871.html
JavaScript代码：
(function () { var FLM = function (id,rowCount,colCount, minLandMineCount, maxLandMineCount) { if (!(this instanceof FLM)) return new FLM(id, rowCount, colCount, minLandMineCount, maxLandMineCount); this.doc = document;

} }; window.FLM = FLM; })();
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：
| Demo |
剩余雷数：
0
持续时间:
0 s
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
各位朋友们，果断地把你们的成绩截图晒出来吧！！！
