I am trying to get value of selected item from dropdown menu via val()

  • 0

I am trying to get value of selected item from dropdown menu via val() method. It works greatly when I use it in plain html withou jquerymobile divs. but when i put in into my content div it isnt working. Here is the code (only content div implemented):

header.php

<!DOCTYPE html> 
<html> 
   <head> 
   <meta charset="utf-8">
   <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">

   <title>RSS Reader</title> 

   <link rel="stylesheet" href="main/jquery.mobile-1.1.0.min.css" />
   <script src="main/jquery-1.6.4.min.js"></script>
   <script src="main/jquery.mobile-1.1.0.min.js"></script>

</head> 
<body>

settings.php:

<?php
include('../main/header.php');
$siteNumber = empty($_GET['siteNumber']) ? 'Živé' : $_GET['siteNumber'];
?>
<div data-role="page">
    <div data-role="header">
        Nastavenia
    </div>
    <div data-role="content">
        <select id="training" name="training" data-native-menu="false">
         <option value="1">Živé</option>
         <option value="2">MobilMania</option>
         <option value="3">Automoto</option>
        </select>
        <script>
            function displayVals() {
            var defaultSiteNumber = $($("#training")[0]).val();
            $("p").html("<b>defaultSiteNumber:</b> " + 
                  defaultSiteNumber);
             }

             $("select").change(displayVals);
             displayVals();
        </script>
    </div>
    <div data-role="footer">
      <div data-role="navbar">
        <ul>
           <li><a href = "../index.php?siteNumber=<?php echo $siteNumber;?>" data-icon="home">Späť</a></li>
           <li><a href = "settings.php?save=true" data-icon="gear">Hotovo</a></li>
        </ul>
      </div>   
    </div>
</div>

After I get those values into javascript I need them to be also available in PHP variables so I can use them to create config file. Or do you think it would be simplier to create config file with javascript? It should be basic .ini with structure which is acceptable by parse_ini_file

EDIT: I have aded whole code including headerp.php to make sure that there is no other error causing this problem.
