Issue with JQuery UI tabs while clicking the button

I am using Jquery UI tabs. I will try explain you my problem, so here is my jquery codes for UI ajax Tabs.

$(function () {
$("#tabs").tabs({

    beforeLoad: function (event, ui) {
        if (ui.tab.data("loaded")) {
            event.preventDefault();
            return;
        }

        ui.ajaxSettings.cache = true;
        ui.panel.html(loading),
        ui.jqXHR.success(function() {
            ui.tab.data( "loaded", true );
        }),
        ui.jqXHR.error(function () {
            ui.panel.html(
            "An error occured while loading a page.");
        });
    }
});
});

At the page index.php you can see HTML codes for UI tabs.

index.php

<div id="tabs">
<ul>
  <li><a href="sections.php?id=1"></a></li>
  <li><a href="sections.php?id=3"></a></li>
  <li><a href="sections.php?id=6"></a></li>
  <li><a href="sections.php?id=8"></a></li>
</ul>
</div>

So, as you see my ajax tabs load the page sections.php. On sections.php I have a select box and I get couple options, depending on status_id.

sections.php

<?php
$status_id = (int) $_GET['id'];

$options_array = array(
1 => array(1 => 'option1', 'option2', 'option3'),
3 => array(4 => 'option4', 'option5', 'option6'),
6 => array(7 => 'option7', 'option8', 'option9'),
8 => array(10 => 'option10', 'option11', 'option12)'
);
?>

<select name="select_box">

<?php

    foreach($options_array[$status_id] as $key => $options)
    {
      echo '<option value="'.$key.'">'.$options.'</option>';
    }

?>
</select>

<button type="submit" name="button1">My Button</button>

Using jquery script at below I am able to alert the selected value of select_box.

<script>

    $('button[name="button1"]').click(
        function () {

            var value = $('select[name="select_box"]').val();
            alert(value);

            return false;
        }
    );


</script>

My question:

For example, I select second tab (sections.php?id=3) and click the button, dialog displays the number 4, that is right. Then I select next option, dialog displays the number 5, that is right too. Now, I am clicking the next tab, for example (sections.php?id=6) and click the button again. Now dialog should display me the number 7, but displays previous number:5. How can this be?

EDITED

Here is simple Fiddle Demo:

Current code logic:

  • your $('select[name="select_box"]') will indeed return a list of all dropdowns with a name of select_box

  • but the expression $('select[name="select_box"]').val() will just return the value of the first dropdown

  • thing you need to fix: always get the selected value from the dropdown which lays down within the active tab

One other solution (beside the one provided by @A J would be:

// Reference only the select dropdown within an active tab
var value = $('div[aria-expanded="true"] select[name="select_box"]').val();

See this updated fiddle and continue reading more about jQuery.val() here. As it's said:

Get the current value of the first element in the set of matched elements or set the value of every matched element.

The current code shows tha value of first dropdown. Modify the click even as following;

$('button[name="button1"]').click(
    function () {

        var value = $('select[name="select_box"]:visible').val();
        alert(value);

        return false;
    }
);

Check this fiddle

This will select the dropdown which is visible and ignore the dropdowns that are hidden.

Try using:

var value = $('select[name="select_box"]:visible').val();

Or

var value = $(this).parents('#tabs').find('select:visible:first').val();

instead of 

var value = $('select[name="select_box"]').val();
