怎么程序就是出不来呢
for(i=0;i<10;i++){
if(infos[i][3]=="大一" && infos[i][1]=="女")
{
document.write(infos[i][0]+"<br>");
}

var infos=new Array();
for(var i=0;i<10;i++){
infos[i]=new Array();
for(var j=0;j<4;j++){
infos[i][j]=[["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"]];
这样。。。
