  已采纳

  var infos=new Array(['小A','女',21,'大一'], ['小B','男',23,'大三'], ['小C','男',24,'大四'])  这样写  没有你那种写法吧

  写法：[1]

            var infos=new Array(1,2,3)

           [2]         

           var infos=[1,2,3]

          [3]         

           var infos=new Array()

           infos[0]=1;

           infos[1]=2;

           infos[1]=3;

      

  1 0

  我們

  非常感谢！谢谢

  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"]];    //双引号，双引号，双引号，谁说不能这样写的

   //第一次筛选，找出都是大一的信息

   document.write("大一的有");

   for(i=0;i<infos.length;i++){ 

         if(infos[i][3]=="大一"){ 

   document.write(infos[i][0]+"、");

         } }

         

   //第二次筛选，找出都是女生的信息

   document.write("<br/><br/>"+"女生有");      

   for(i=0;i<infos.length;i++){  

   if(infos[i][1]=="女"){  

   document.write(infos[i][0]+"、");

         } 

  }
