忽略掉全都是一樣的信息這個“bug”，嫌麻煩所以復制的，題目是：輸出所有是大一的女生，請問這代碼哪寫錯了，為啥一個都輸出不了呢，請指正

?var infos[["小a","女",21,"大一"],["小b","女",21,"大一"],["小c","女",21,"大一"],["小d","女",21,"大一"],["小e","女",21,"大一"],["小f","女",21,"大一"],["小g","女",21,"大一"],["小h","女",21,"大一"],["小i","女",21,"大一"],["小j","女",21,"大一"]];

?for(var i=0;i<infos.length;i++){
???? var jr=infos[i][3];
???? var wx=infos[i][1];
???? if(wx=="女" && jr=="大一"){
???????? document.write(infos[i]+"<br/>");
???? }
?}
