javascript - Populate Materialize autocomplete with json data -


i'm building little website project , i've been searching hours how populate autocomplete input using materialize plugin. i'm not familiar json or ajax i'm in pain doing it. original example doc comes static data :

$('input.autocomplete').autocomplete({ data: {   "apple": null,   "microsoft": null,   "google": 'http://placehold.it/250x250' }, limit: 20, // max amount of results can shown @ once. default: infinity. onautocomplete: function(val) {   // callback function when value autcompleted. }, minlength: 1, // minimum length of input autocomplete start. default: 1. });

my wish dynamic data database. i'm using php code so:

<?php         $query = $arg;         echo $query;          $json_output = array();         $reponse = $bdd->query("select cpnom competence cpnom ". $query);          while ($donnees = $reponse->fetch()) {                      $json_output[] = $donnees[0]. ": null";                         }          return json_encode($json_output); ?>

i'm assuming code working because displays ["java":null, "js":null, "c":null] match database datas. idea how put json data in data argument instead of static names?

data: {   "apple": null,   "microsoft": null,   "google": 'http://placehold.it/250x250' }

thank time!

  var data_2 = json.parse(sessionstorage.getitem('key_1'));        $(function() {          $('input.autocomplete').autocomplete({          data: data_2,        limit: 20, // max amount of results can shown @ once. default: infinity.      onautocomplete: function(val) {          // callback function when value autcompleted.      },      minlength: 2 // minimum length of input autocomplete start. default: 1.          });      });

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
