javascript obtain value of select option without submitting form -

-

i'm trying value of input select option without submitting form (need keep available while displaying live results). need use value global variable inserted in array later on. because can't use submit, need find way update value if user changes option (ie using onchange).

here's have (doesn't work):

html

<select id="color" >     <option value="">select:</option>     <option value="blue">blue</option>     <option value="red">red</option>     <option value="yellow">yellow</option> </select>


javascript

document.getelementbyid('color').onchange = function() {     var colorinput = this.value;     console.log(colorinput); };


updated

okay, no using inline javascript, it. updated script above reflect of answers i'm getting - not addressing central problem. tracking input option value within script no problem; need value global variable. reason can't it.

here's jsfiddle analogous how need use it: http://jsfiddle.net/agvrn/2/

it should able track select option (already can) , must able use value in separate function - in case inserting paragraph field "show".

don't use inline javascript.

try (avoiding global variables):

(function() {     var select_val;     document.getelementbyid('color').addeventlistener('change', function() {         select_val = this.value;         document.getelementbyid("show").innerhtml = select_val;     }, false);  })();

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