php - Drupal 7 ajax not working properly (success function called but the drupal page is being printed instead of the page callbacks results) -


hello using ajax in drupal 7 data bounds of map serialize string , submit post server added filter view make display respond changes in zoom , array bounds.

the success callback called data returned not result of page callback function , xhtml response in firebug entire web page. appreciate knowing preventing page callback function value being returned.

below javascript code:

    (function ($) {     drupal.behaviors.mapresults = {     attach: function() {   // dynamically show  marker nodes      // first find right map     $.each(drupal.settings.getlocations, function (key, settings) {     // 1 want     alert("0");     if (1 == 1) {       // event handler on map zoom check if view results needs updated            on zoom        // hooking event , checking zoom may work better.       google.maps.event.addlistener(getlocations_map[key], 'bounds_changed', function()       {          // count number of markers <= 10'         // global_settings.mgr         //mgr = new markermanager(getlocations_map[key]);           //zoomcount = mgr.getmarkercount(getlocations_map[key].getzoom());          zoomcount = 10;          if(zoomcount < 100){              // bounds              marker_bounds = getlocations_map[key].getbounds();             // calculate horizontal distance bounds max  , min latitude ,          longitude for box         // submit data jquery bounds etc.         var marker_bounds_string = json.stringify(marker_bounds);          // ajax link submit data post         $.ajax({             type: 'post',             url: 'ajax/mapresults',             datatype: "json",                                data : {marker_bounds : marker_bounds_string},                          success: function (data)          {document.getelementbyid('map_results').innerhtml = "success";},             error: function (xmlhttp)        {document.getelementbyid('map_results').innerhtml = xmlhttp.status;}             });           }          else{           }       });     }   }); } }; }(jquery));

here drupal module code:

    <?php function mapresults_menu() {   $items['ajax/mapresults'] = array(     'title' => t('mapresults ajax'),     'type' => menu_callback,     'page callback' => 'mapresults_ajax',     'access arguments' => array('access content'),   );   return $items; } function mapresults_ajax() { // call display map options drupal_exit(); $view = views_get_view('search');  // set display $display_id = 'default';  // add filters ajax // float $bounds_array = json_decode($_post['marker_bounds'])  //get cordinates bounds_array $lat_min = $bounds_array[0][0]; $lat_max = $bounds_array[1][0]; $lon_min  = $bounds_array[0][1]; $lon_max = $bounds_array[1][1];  // add filters view $view->exposed_input['ubicacion_latitiude'] = $lat_min; $view->exposed_input['ubicacion_latitiude_1'] = $lat_max; $view->exposed_input['ubicacion_longitude'] = $lon_min; $view->exposed_input['ubicacion_longitude_1'] = $lon_max;  $view->pre_execute(); $view->execute();  // display ajax results in container $data = $view->preview($display_id); $results_count = count($view->result);  if($results_count <= 10){     // return json           drupal_json_output($data);// drupal_exit(); } else{     drupal_json_output("ih"); drupal_exit();     } } ?>

mapresults_ajax not returning anything. in case, use print instead of return send results javascript without returning whole html page.

change drupal_json_output print drupal_json_output

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
