javascript - Array created from .get() won't populate html select -

-

this question has answer here:

here's rundown. have external .txt file has number of locations (one per line) need have loaded script populate dropdown. i'm using .get() pull in data, , putting array. looks correct, dropdown isn't populated. doing tests, found if manually populate array when declare data declare there loads fine. also, if try doing array such turning string nothing happens, , if try checking length reports 0. i've tried making new array , pushing content of first it, no dice. i've tried using makearray, didn't work.

here's code far:

var siteidarray = []; var path = "*snipped*/siteid.text"; var option = "";  $.get(path, function(data) {   siteidarray = data.split("\n");   console.log(siteidarray); });  (i = 0; < siteidarray.length; i++) {   option += '<option value="'+ siteidarray[i] + '">' + siteidarray[i] + '</option>'; } $('#siteid').append(option);

here's test of siteidaarray contains (full array has total of 62 items):

["an", "az", "ba", "ca"]

and siteid.txt looks this:

an az ba ca

$.get async call, have work response object inside callback or pass function:

$.get(path, function(data) {   siteidarray = data.split("\n");   console.log(siteidarray);    (i = 0; < siteidarray.length; i++)   {       option += '<option value="'+ siteidarray[i] + '">' + siteidarray[i] + '</option>';   }   $('#siteid').append(option); });

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 $row): ?> <div id="<?=$...
