数组排序
<html>
<body>
<script type="text/javascript">
function sortNumber(a, b)
{
return a - b
}
var arr = new Array(6)
arr[0] = "10"
arr[1] = "5"
arr[2] = "40"
arr[3] = "25"
arr[4] = "1000"
arr[5] = "1"
document.write(arr + "<br />")
document.write(arr.sort(sortNumber))
</script>
</body>
</html>
结果:
10,5,40,25,1000,1
1,5,10,25,40,1000
其中 function sortNumber(a, b)
{
return a - b
}
这段代码是什么意思 用处是什么?
