javascript - Problems passing '?' in URL to ajax call -

-

i trying create ajax call weatherunderground. code is:

$(".city").autocomplete({     source: function( request, response ) {     $.ajax({         // http://autocomplete.wunderground.com/aq?query=san%20f         url: "http://autocomplete.wunderground.com/aq?query=",         datatype: "jsonp",         data: {             featureclass: "p",             style: "full",             maxrows: 12,             name_startswith: request.term         },         success: function( data ) {             response( $.map( data.results, function( item ) {             return {                 label: item.name + item.countryname,                 value: item.name             };         }));      }  }); }, minlength: 2, select: function( event, ui ) {    log( ui.item ?       "selected: " + ui.item.label :        "nothing selected, input " + this.value);  },  open: function() {     $( ).removeclass( "ui-corner-all" ).addclass( "ui-corner-top" );  },  close: function() {    $( ).removeclass( "ui-corner-top" ).addclass( "ui-corner-all" );    }  });

no matter how treat question mark following aq 'uncaught syntaxerror: unexpected token :' error. if encode ? '?' &? in resulting url. if remove ampersand request functions correctly. if use either encodeurl() on entire string or encodeurlcomponent of ? results %3f doesn't work either.

i ready tear hair out, know do?

the error stems mismatched parameter name rather ? in url.

the parameter @ issue 1 specifies jsonp callback:

http://.../aq?query=san%20f&callback=jquery111___140___&ts=12345 //                          ^^^^^^^^

and, jquery's default name of callback isn't api expecting:

cb           jsonp callback method name

to change parameter, can include jsonp: 'cb' in request options.

$.ajax({     url: "http://autocomplete.wunderground.com/aq?query=san%20f",     datatype: "jsonp",     jsonp: 'cb',      // ... });

example: http://jsfiddle.net/x2jea/

and, syntax error response. without cb parameter, service responding json, lacking "padding" make jsonp.

{"results": ...} //        ^ syntax error 
jquery111___140___({"results": ... }); // padding

note jsonp javascript , requested <script> element. it's taking advantage of 2 languages' similarities in syntax. but, needs padding valid.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
