冒泡函数

<script type="text/javascript">
function bubling (arr){//形参arr
var temp = 0;
var i = 0;
var j = 0;
for(i = 0; i < arr.length; i++) {
for(j = 0; j < arr.length - i; j++) {
if(arr[j] > arr[j + 1]){
temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
}
var arr = [5,3,2,4,1];//实参

bubling(arr);//调用函数并传递实参
