最近在学JavaScript，就用学的知识写了两个充满童年回忆的小游戏--迷宫和打地鼠，现在让我们一起来看看怎么实现吧~
1.简单迷宫
这是一个不能再简单的迷宫了，游戏规则：从迷宫中走到终点就赢了；碰墙就输；从地图外走到终点算作弊。S为起点，E为终点。

js代码
var isStart = false;
var isInMap = false;
window.onload = function () {
var wall = document.getElementsByClassName("wall");
/*start */
document.getElementById("start").addEventListener("mouseover", function () {
document.getElementById("result").textContent = "";
isStart = true;
isInMap = true;
for (var i = 0; i < wall.length; i++) { wall[i].style.backgroundColor = "#EEEEEE"; }
})
/*out of the map */
document.getElementById("wholeMaze").addEventListener("mouseleave", function () {
isInMap = false;
});
/*wall */
for (var i = 0; i < wall.length; i++)
wall[i].addEventListener("mouseover", function (event) {
if (isStart) {
event.target.style.backgroundColor = "#FF0000";
document.getElementById("result").textContent = "You hit the wall, lost the game!";
isStart = false;
}
});
for (var i = 0; i < wall.length; i++)
wall[i].addEventListener("mouseleave", function (event) {
event.target.style.backgroundColor = "#EEEEEE";
});
/*end */
document.getElementById("end").addEventListener("mouseover", function () {
if (isStart) {
if (isInMap) { document.getElementById("result").textContent = "Congratulation! You win the game!"; }
else {
document.getElementById("result").textContent = "Oh, my friend, please don't cheat!";
isStart = false;
}
}
isStart = false;
});
}
js部分的关键在于给元素添加Listener，相当于附加个触发器，一旦事件发生如“mouseleave”(鼠标离开对应元素区域)就调用对应的函数。另外注意面向对象编程。
2.打地鼠
这个游戏比较复杂，也比较有意思，加上了计时和计分功能，还可以控制游戏的开始和结束并显示游戏状态。游戏结束时弹出结果。
游戏规则：打中地鼠加一分，打错扣一分，不打分不变，玩家可以挑战30秒内能打中多少只地鼠。(拼手速的时刻到了~)
