小弟遇到一难题 求大神帮忙
$rs=mysql_query("select * from title");
$row=mysql_fetch_array($rs);
$num=mysql_num_rows($rs);
//echo $num;
for($i=1;$i {
$rs=mysql_query("select * from title where parent_id=$i");
$row=mysql_fetch_array($rs);
//print_r($row)
?>

$sql="select * from index_kind where parent_id=$i";
$rs=mysql_query($sql);
while($row=mysql_fetch_array($rs))
{
?>
')" onMouseOut="omout(this)" id="">
}
?>
(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 $row["good_img"];
}
?>
(这里是AJAX)
function omo(obj,str)
{
//alert(str);
obj.style.borderBottom="1px solid #e4393c";
//alert(obj.id);
var xmlhttp;
if(window.XMLHttpRequest)
{
xmlhttp=new XMLHttpRequest();
}
else
{
xmlhttp=new ActiveXObject("Microsoft.XMLHttp");
}
xmlhttp.open("get","chuli.php?id="+obj.id,true);
xmlhttp.onreadystatechange=function(){
//alert(xmlhttp.readyState)
if(xmlhttp.readyState==4)
{
alert(xmlhttp.responseText)
document.getElementById(str).innerHTML="
}
}
xmlhttp.send(null);
}
这是我测试用的数据库
然后当我移到这个划红线的地方是弹出的是图片的地址
我想让图片显示在下方的黑框里 但是弄不出来啊 !!! 求大神帮帮忙解决下问题!!!
回复讨论(解决方案)
既然你 document.getElementById(str).innerHTML="";
那么 xmlhttp.responseText 中就应该是一个合法的图片路径
而你 alert(xmlhttp.responseText) 看到的却是多个,把这多个图片名当做一个图片的路径,无论如何也是不会显示的
这个我知道 因为$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
