备注：由于小程序的特殊原因，上面的赋值过程有点冗长，其他开发环境可以直接把数组元素直接赋值给另一个数组元素然后return出来就可以了：例如
2.
functionbubbleSort(arr){
3.
varlenarr.length;
4.
for(vari0;ilen;i++){
5.
for(varj0;jlen-1-i;j++){
6.
if(arr[j]arr[j+1]){//相邻元素两两对比
7.
vartemparr[j+1];//元素交换
8.
arr[j+1]arr[j];
9.
arr[j]temp;
10.
}
11.
}
12.
}
13.
returnarr;
14.
}
