//第一步把之前的数据写成一个数组的形式,定义变量为 infos

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"]];

//第一次筛选，找出都是大一的信息

switch(infos)

{

for (var i = 0; i<infos.length; i++) {

if(infos[i][3] == "大一" && infos[i][1] == "女"){ //筛选3:大一 1 ：性别女

document.write("大一的女生的名字：" + infos[i][0] + "<br/>")

}
