為什么我得到的結(jié)果是一個A兩個逗號。。。。。
<script type="text/javascript">
var name=['A','B','C','D','E','F','G','H','I','J'];
var sex=["女","男","男","女","女","男","女","女","女","男"];var age=[21,23,24,21,22,21,22,20,20,20];
var aclass=["大一","大三","大四","大一","大四","大一","大四","大一","大二","大三","大一","大三"];
var person=[name,sex,age,aclass];
?//第一步把之前的數(shù)據(jù)寫成一個數(shù)組的形式,定義變量為 infos
?for(var i=0;i<10;i++){
? ? ?var infos=person[3][i];
? ? ?if(infos=="大一"){
? ? ? ? ?var infoa=person[1][i];
? ? ? ? ?if(infoa=="女"){
? ? ? ? ? ? ?document.write(person[0][i]+"<br />");
? ? ? ? ?}
? ? ?}
? ? ?}

你把數(shù)組名name換個名字就好了，，比如用var names=[............]

我在這里看到了你想要的答案。說的是：
window.name?是?DOM?對象?window的一個屬性name?主要用于為超鏈接和表單設(shè)置目標(biāo)（target）window。
具體原理，我也不清楚，猜測是name原本的預(yù)設(shè)的功能并沒有失效導(dǎo)致的混亂吧。要是你查到了，煩請告訴我答案。

結(jié)果了然，只是原理問題，正在詢問度娘 - -
