学深搜的时候想起来了这个游戏，于是就想用深搜还原一下，练练手。不要看这个游戏这么简单，要考虑的东西还不少呢，写游戏真的很麻烦。

1. 首先是HTML：
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">

<body>
<div class="maze">
<div class="head">【地下迷宫】<a href="#" id="rule">规则</a></div>
<div class="table">
<div id="tip" style="visibility: visible;">走的时候不妨体验一下其它路线，不要为了找出口而走</div>
<div class="block1" style="margin-left: 30px;"></div><div class="block1"></div><div class="block1"></div><div class="block1"></div><div class="block1"></div><div class="block1"></div><div class="block1"></div><div class="block1"></div>

</div>
<div class="bottom">
<a href="#" id="start">开始</a>
<a href="#" id="reset">结束</a>
</div>
</div>
<script type="text/javascript" src="maze.js"></script>
</body>
</html>2. 然后是CSS：
.maze{
display: inline-block;
width:300px;
height: 260px;
position: absolute;;
left: 50%;
top:10px;
margin-left: -150px;
border: 1px solid black;
}
#tip{
position: absolute;
z-index: 2;
background-color: red;
width: 100%;
top:30%;
color: #fefefe;
padding-top:3px;
padding-bottom: 3px;
text-align: center;
font-size: 16px;
}
.head{
display: inline-block;
width: 150px;
position: absolute;
left: 50%;
margin-left: -75px;
margin-top: 5px;
}
.head>a{
margin-left: 10px;
}
.table{
position: absolute;
top:50px;
}
.block1{
display: inline-block;
position: relative;
width: 30px;
height: 20px;
line-height: 20px;
text-align: center;
}
.bottom{
position: absolute;
left: 50%;
bottom: 10px;
margin-left: -55px;
}
.bottom>a{
margin-left: 10px;
padding-right: 20px;
}3. 最后是精华部分，JS代码：

}
//按键绑定函数操作-4我生成迷宫的方案是先用深搜搜出一可以走到终点条路线，然后再随机生成起点和终点，再搜从起点到终点的路线。如果有更好的方案，欢迎留言啊。
