jQuery制作拼图小游戏,jquery拼图小游戏

源代码思路分析:

【一】如何生成图片网格,我想到两种方法:

   (1)把这张大图切成16张小图,然后用img标签的src

   (2)只有一张大图,然后每个元素的背景图用css的background-position进行切割定位,这样就需要16个数组[0,0],[-150,0],[-300,0]..........(我采用这种)

【二】图片背景定位数组与布局定位数组

  在选择了使用CSS定位切图,就需要生成数据。

     需要的css背景 定位数组为:[0,0],[-150,0],[-300,0]yzc216亚洲城,,[-450,0],

                [0,-150],[-150,-150],[-300,-150],[-450,-150],

                [0,-300],[-150,-300],[-300,-300],[-450,-300],

                [0,-450],[-150,-450],[-300,-450],[-450,-450]

     它们当中都用到了[0,-150,-300,-450]其中的值(就是我定义图片高,宽150的倍数值),所以就利用这个值通过for(){}自动生成数组

复制代码 代码如下:

      //this.nCol在这里是4 --- 因为我的拼图是4*4
         // this.nArea是150,是每张图片的宽,高(600px/4)--大图是600*600
            var l = [],
                p = [];
            for(var n=0;n<this.nCol;n ){
                l.push(n*(this.nArea 1));     //生成[0,151,302,453] 网格的布局定位数组,因为我的效果需要边框(图中的绿色边框),所以与css背景定位数组就不一样了
                p.push(-n*this.nArea);         // 生成了[0,-150,-300,-450]就是上面说的,CSS背景定位值
            }
            for(var i=0;i<this.nLen;i ){   // this.nLen 是为 16  
                var t = parseInt(i/this.nCol),
                        k = i - this.nCol*t,
                        aP = [],
                        aL = [];
                    aP.push(p[k],p[t],i); //这里我给css背景定位数组额外加了i,是为第3步判断用的,不需要拿来设置css属性的,我把它设置为标签的属性里[bg-i]
                    aL.push(l[k],l[t]);
                    this.aBgp[i] = aP;
                    this.aLayout[i] = aL;               
            }

【三】判断是否完成

        第二个元素(div)应用了css背景定位  this.aBgp[1] (值为[-150,0,1]) ,而随机分配的布局定位假如是this.aLayout[3] (这里的3是随机生成的)(值为[453,0]),那么left:453px,top:0;

       挪动这个元素,改变的是它的letf,top值,而不是本身结构的顺序,获取这个元素的left,top的值(假如是挪到left:151px,top:0),然后拿来与this.aLayout[1]的值[151,0](里面的1索引,就是本身标签属性的[bg-i]=1也是this.aBgp[1] 的索引)判断,相等就说明这个元素挪动后的位置是正确。

        this.aRowBgp = option.aRowBgp || [0,-150];//布局竖向数组
        this.nCol = this.aColLayout.length;
        this.nRow = this.aRowLayout.length;
