javascript - Iterating through mutiple checkbox values and matching them against a single text input box's value with jQuery -

-

i trying check if value string of text input field contains matches correspond values of multiple checkbox inputs. if checkbox's value found match within text input's value string, checkbox should checked, while unmatching checkbox should remain unchecked. code below, of checkboxes show checked, while 1 of checkbox's value match text input's value string.

jquery

$("input[type='checkbox'][name='hello']").each(function(){     var value = $(this).attr('value');     var id = $(this).attr('id');       if ($("input[type='text'][name='goodbye']:contains("+value+")")) {         $("input[id="+id+"]").prop('checked', true);     } });

html

<input type="checkbox" name="hello" id="1" value="1"><label for="1">one</label> <input type="checkbox" name="hello" id="2" value="2"><label for="2">two</label> <input type="checkbox" name="hello" id="3" value="3"><label for="3">three</label>  <input type="text" name="goodbye" id="goodbye" value="1">

if want text compare following should work

$("input[type='checkbox'][name='hello']").each(function () {     var value = $(this).val();      if ($('#goodbye').val().indexof(value) >= 0) {         $(this).prop('checked', true);     } });

i'm not sure why going overly complicated goodbye input, since had id , id unique (or you'll have other issues). 

$('#goodbye').val()

will give value in input box. using indexof return -1 if value not found, number 0 or greater if is, can use figure out if value exists.

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