向Array中添加冒泡排序

冒泡排序思想

冒泡排序实现

Function.prototype.method = function(name, func){
this.prototype[name] = func;
return this;
};
Array.method('bubbleSort', function(){
var len = this.lenght,
i, j, tmp;
for(i=0; i<len; i++){
for(j=len-1; j>i; j--){
if(this[j] > this[j-1]){
tmp = this[j-1];
this[j-1] = this[j];
this[j] = tmp;
}
}
}
return this;
});
