php - Search for tab and replace it with active one -


problem:

to search tab containing class "active" , remove while adding "active" class current tab on php post submission.

i have tab menu looks this.

html code:

<div class="pull-right special-search" id="navtabs">     <div class="btn-group">         <a href="#tab1" class="active btn btn-info" data-toggle="tab"><i class="icon-home icon-white"></i>&nbsp;start</a>         <a href="#tab2" class="btn btn-info" data-toggle="tab"><i class="icon-book icon-white"></i>&nbsp;essay</a>         <a href="#tab3" class="btn btn-info" data-toggle="tab"><i class="icon-ok-sign icon-white"></i>&nbsp;criteria</a>         <a href="#tab4" class="btn btn-info" data-toggle="tab"><i class="icon-time icon-white"></i>&nbsp;activity</a>     </div> </div>

to toggle between these tabs use following jquery code:

$('#navtabs a[data-toggle="tab"]').on('shown', function (e) {     e.target;     e.relatedtarget;     $('#navtabs a[data-toggle="tab"]').attr('class','btn btn-info');     $(this).attr('class','active btn btn-info'); })

so far, good. works. now, when press button "submit-updatetime" want checked php correspondent tab sent from. using hidden type field:

<input type="hidden" id="submit_button" name="button_pressed">

and check php using following code:

<?php     if ($_server['request_method'] == 'post')      {         $button = $_post['button_pressed'];          if ($button == 'submit-updategrades')             $tabname = 'tab2';         else if ($button == 'submit-updatetime')             $tabname = 'tab4';     } ?>

to make sure user stays on tab he/she on use following php/jquery:

<?php                if (!empty($tabname))     {         echo '$("#navtabs a[href=#tab1]").removeclass(\'active\');';         echo '$("#tab1").removeclass(\'active\');';         echo '$("#navtabs a[href=#'.$tabname.']").addclass(\'active\');';         echo '$("#'.$tabname.'").addclass(\'active\');';     } ?>

this works fine except feel last php/jquery solution flawed. instance, #tab1 active when enter page, not time.

question:

how in last php/jquery code search tab has class "active" , remove while @ same time add active tab produced $tabname?

ho wo find tab has active class:

$(document).ready(function(){     var tab = $('#navtabs a.active'); });

remove active class on tab found:

$(document).ready(function(){     var tab = $('#navtabs a.active');     tab.removeclass('active'); });

find, remove , add active class tab provided php:

<?php            if (!empty($tabname)) { ?> $(document).ready(function(){     var active_tab = '#<?php echo $tabname; ?>';     var tab = $('#navtabs a.active');     tab.removeclass('active');     $('#navtabs a').each(function(){         if($(this).attr('href') == active_tab) {             $(this).addclass('active');             return;         }     }); }); <?php } ?>
