js 对文字排序和对数字排序

1、对文字排序

<html>
<body>

<script type="text/javascript">

var arr = new Array(6)
arr[0] = "George"
arr[1] = "John"
arr[2] = "Thomas"
arr[3] = "James"
arr[4] = "Adrew"
arr[5] = "Martin"

document.write(arr + "<br />")
document.write(arr.sort())

</script>

</body>
</html>

结果：

George,John,Thomas,James,Adrew,Martin
Adrew,George,James,John,Martin,Thomas

2、对数字进行排序

<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>
