$. Ajax ({
Type: "POST ",
Url: "class. php ",
Data: "bid =" + bid,
Success: function (data ){
$ ("# Xlm2" ).html ("classification:" + data );
}
});

while($r=$cms->fetch($mesql)){ 
   $classname.= $r[classname];
}
echo $classname;

In this way, the output is normal:

Category: Column 1, column 2, column 3 ......

Now I want to output one more topic Image:

Category: Column 1, column 2, column 3 ......

How should I change it?

$. Ajax ({
Type: "POST ",
Url: "class. php ",
Data: "bid =" + bid,
DataType: "json ",
Success: function (data ){
$ ("# Xlm1" ).html ("");
$ ("# Xlm2" ).html ("classification:" + data );
}
});

while($r=$cms->fetch($mesql)){ 
   $classname.= $r[classname];
   $img= $r[img];
}
echo json_encode(......);

------ Solution ----------------------
While ($ r = $ cms-> fetch ($ mesql )){
$ Classname. = $ r [classname];
$ Img = $ r [img];
}
Echo json_encode (array ('data' => $ classname, 'IMG '=> $ img );
------ Solution ----------------------
How to write? Based on your needs

It seems that you are not talking about js, so you can assemble html in php and then return it. Don't use any json (same as your first example)

In fact, if JavaScript is used to assemble HTML, it is better to use php to assemble HTML.
