(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)
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。
