    赋值内容错误

    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
