調(diào)用sortNum不應(yīng)該是sortNum()嗎？
<script?type="text/javascript">
??function?sortNum(a,b)?{
??return?a?-?b;
?//升序，如降序，把“a?-?b”該成“b?-?a”
}
?var?myarr?=?new?Array("80","16","50","6","100","1");
??document.write(myarr?+?"<br>");
??document.write(myarr.sort(sortNum));
</script>

不帶括號(hào)的調(diào)用 function ： 函數(shù)體對(duì)象為參數(shù)
帶括號(hào)的調(diào)用 function（）：立即執(zhí)行函數(shù)后返回的值為參數(shù)
