1.简介

非常简单的一个网络消消乐翻牌小游戏的实现，代码量较少，不过遇到的bug和自行开发的步骤十分有纪念意义。

2.核心代码块

生成随机数列，确定图片随机分布

function getImgIndex(is){var index = parseInt(Math.random()*8)+1;if(is[index] < 2){is[index]++;} else {index = getImgIndex(is);}return index;}

通过window.onload函数定义8个背景图片随机分布

window.onload = function(){//规则：五个背景图，每张图出现两次，随机分配到16个div中var ele = document.getElementById("parent");var imgs = [1,2,3,4,5,6,7,8]; 				var is = [0,0,0,0,0,0,0,0,0];for(var i = 0; i < 16; i++){var index = getImgIndex(is);console.info(index);ele.innerHTML += "<div id='k"+i+"' class='kid' "+"οnclick='oclick(this.id,"+index+");'></div>";	//通过字符串拼接方式，将H5代码发送给网页执行			}}

点击图片事件
oclick函数中利用f存储上个图片的index,；利用id2存储上个图片的id
再进行以下操作比较

function oclick(id,index){   if(find[index]<2){if(f==0){find[index]++;look(id,index);f=index;id2=id;}else{if(f==index&&id!=id2){   find[index]++;look(id,index);f=0;id2=0;marked++;}else{   find[f]=0;look(id,index);look(id2,f);clearStyle(id);clearStyle(id2);f=0;id2=0;}}}if(marked==8){alert("恭喜完成");}}

图片操作函数

function look(id,index){var ele = document.getElementById(id);ele.style="background-image: url("+index+".gif);";}function clearStyle(id){setTimeout(function(){var ele = document.getElementById(id);ele.style="";}, 200);}

重置页面函数

function re(){window.location.reload();}

页面的设计

	<body><div id="parent" class="par"></div><input type="button" name="b1" id="b1" value="再van♂一次" onclick="re();"/></body>

3.已知bug 说明（已解决）

1.点击图片本身两次导致匹配成功
解决方式：加入id判断是否为自身比较

f==index&&id!=id2

2.已匹配的图片再次点击会消除
解决方式：加入find[]数组统计图片点击次数，超过两次不再比较

if(find[index]<2)
