你这for循环写的可不对啊，看下for的语法吧~

最好还是先赋值，然后再循环判断吧，这样关系不是太乱了吗。很难看清楚错那的，你像这样
var infos=[["小A","女",21,"大一"],["小B","男",23,"大三"],["小C","男",24,"大四"],["小D","女",21,"大一"],["小E","女",22,"大四"],["小F","男",21,"大一"],["小G","女",22,"大二"],["小H","女",20,"大三"],["小I","女",20,"大一"],["小J","男",20,"大三"]];
for(i=0;i<=4;i++){
if(infos[i][3]=="大一"&&infos[i][1]=="女"){
document.write(infos[i][0]);
}
}
试试呢
