(这是ajax的处理)

require_once 'conn.php';
$child_id=$_GET["id"];
$rs=mysql_query("select * from index_kind where child_id='$child_id'");
$row=mysql_fetch_array($rs);
$nums=mysql_num_rows($rs);
for($i=1;$i {
echo $row["good_img"];
}
?>


(这里是AJAX)
function omo(obj,str)
{
//alert(str);
obj.style.borderBottom="1px solid #e4393c";
//alert(obj.id);
 var xmlhttp;
     if(window.XMLHttpRequest)
     {
      xmlhttp=new XMLHttpRequest();
     }
     else
     {
         xmlhttp=new ActiveXObject("Microsoft.XMLHttp");
     }
  xmlhttp.open("get","chuli.php?id="+obj.id,true);
  xmlhttp.onreadystatechange=function(){
            //alert(xmlhttp.readyState)
              if(xmlhttp.readyState==4)
              {
                 alert(xmlhttp.responseText)
 
 document.getElementById(str).innerHTML="小弟遇到一难题 求大神帮忙";
 
              }
         }
     xmlhttp.send(null);
}

这是我测试用的数据库



然后当我移到这个划红线的地方是弹出的是图片的地址




我想让图片显示在下方的黑框里  但是弄不出来啊  !!! 求大神帮帮忙解决下问题!!!

回复讨论(解决方案)

既然你 document.getElementById(str).innerHTML="小弟遇到一难题 求大神帮忙";
那么 xmlhttp.responseText 中就应该是一个合法的图片路径
而你 alert(xmlhttp.responseText) 看到的却是多个,把这多个图片名当做一个图片的路径,无论如何也是不会显示的

这个我知道   因为$row[good_img]是一个数组嘛   我就是不知道怎么把这个数组里面的路径  一个一个去显示成图片 

服务器端json后,传回来,再用js的eval拆开一个一个循环看看

求代码  怎么拆开一个个循环
