    引用:

    引用:
    while($mem = mysql_fetch_assoc($result)) //循环开始
    {
    echo $men['username'];
    echo $men['bbsname'];
    }

    这样会重复吗?看看
    ?>


    这样显示空白了 不能输出


    在循环里 var_dump($m……

    ------解决方案--------------------
    box.innerHTML+=box.innerHTML;这句的问题
    这样假设 box.innerHTML 为 '111';
    那么 box.innerHTML+=box.innerHTML; 后,box.innerHTML 为 '111111';
