jQuery Forum

This is the jquery function:

1.   $(function() {
         $( "#namn" ).autocomplete({
            source: "ajax_seekkund.asp?seekstr="+$("#namn").value+"&dum="+Math.random(),
            minLength: 2
         });
     });

You don't show any code, so its pretty tough to be specific.

My post at the bottom of this link has: 1 a link to a tutorial that discusses several databases, 2. some working Autocomplete code for a remote server data source, and 3. some tips.

https://forum.jquery.com/topic/autocomplete-how-to-use-mysql-data

 

1.   $(function() {
         $( "#namn" ).autocomplete({
            source: "ajax_seekkund.asp?seekstr="+$("#namn").value+"&dum="+Math.random(),
            minLength: 2
         });
     });
And the data recieved from the source-file is "Test1","Test2" in json-format. Nothing else

You're using the source: option to send data to your server. This can work, but the data: option is intended to do this, especially for several pieces of data.  So something like

data: { seekstr: $("#namn").value(),
           dum: Math.random()
         }

Is there a reason to put the Autocomplete inside an an anonymous function - that you can't call from elsewhere in the code?  I would remove the function - 1st and last lines of your posted code.

The data example (Test1, Test2) is not JSON. Have you copied the server's response out of the Console in Firebug or Chrome Developer Tools, pasted it into jsonlint.com and validated that your server produces JSON?

These are some starting thoughts. Lets see what happens.

That's a Javascript array [  ]  of strings "   "    ["    ", "    ", "      "]   They work also.

Glad you got it working.

1.  SQL = "SELECT Kund_Namn FROM KUNDER WHERE Kund_Namn LIKE '%" & Request("seekstr") & "%'"
    Set RS=Connection.Execute(SQL)
    svar = "["
    if NOT RS.EOF then
     do until RS.EOF
      svar = svar & """" & RS("Kund_Namn") & """" & ", "
2.    RS.MoveNext
     loop
     str = len(svar)-1
     svar = left(svar,str)
     svar = svar & "]"
3.  else
     svar = 0
    end if
    
   RS.Close
   Connection.Close
   Set Connection=Nothing
   'Response.Write "[" & """Test1""" & ", " & """Test2""" & "]" (This works)
   response.write svar      (This doesnt)

I don't follow your server code. BTW, it is vulnerable to hacks. Assume your data will be hacked.
Here's some PHP that generates JSON. If you modify and use something like this,  you will need to add an option to the Autocomplete code to tell it that it will receive JSON.    dataType: JSON
The tutorial I referred you to describes more.
Here's PHP code to generate JSON for Autocomplete

    $fetch = mysql_query("SELECT DISTINCT neighborhood, borough FROM places.neighborhoods
                          WHERE city='$city' AND stateProvinceAbbrv='$state' AND countryAbbrv='$country'
                          AND neighborhood LIKE '". mysql_real_escape_string($_POST['term']) ."%'
                          LIMIT 0,7");
                                                                 
    /* Retrieve the query results and store in an array. Specify a MySQL associative array with case sensitive field names.*/
        while ($row = mysql_fetch_array($fetch, MYSQL_ASSOC))
        {    /* In each row, pull neighborhoods and borough. */
            $row_array['name'] = $row['neighborhood'];
            $row_array['value'] = $row['neighborhood'];
            $row_array['borough'] = $row['borough'];         
            array_push($return_arr,$row_array);
        }
/* Toss back neighborhood results as a json encoded array. */
echo json_encode($return_arr);
/* Free connection resources. */
mysql_close($conn);

Certainly, there's a way to do it in ASP, but I don't know the language.
