数组排序sort()这个完全没看懂，求大神指点。
1.使用sort()将数组进行排序，代码如下：
<script type="text/javascript">
var myarr1 = new Array("Hello","John","love","JavaScript");
var myarr2 = new Array("80","16","50","6","100","1");
document.write(myarr1.sort()+"<br>");
document.write(myarr2.sort());
</script>
运行结果：
Hello,JavaScript,John,love
1,100,16,50,6,80
