?//第一步把之前的數(shù)據(jù)寫(xiě)成一個(gè)數(shù)組的形式,定義變量為 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"]];
?//第一次篩選，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"){? //篩選3:大一? 1 ：性別女
???????? document.write("大一的女生的名字：" + infos[i][0] + "<br/>")
????????? }
? }
}
