ui.tabs.add creates two tab panels when using a full URL

Testcase: http://jsfiddle.net/rmEYT/

A unit test has been added based on the test case.

The panel in ui.tabs.add is created only if it's an in-page tab.

2 html files have been added in tests/visual/tabs in order to test this fix.

A proposal to fix the problem is available here : http://github.com/dominiquevincent/jquery-ui/commit/8f69b7546253eb9328b8e72549ff2a7c9d4b2db9 The panel in ui.tabs.add is created only if it's an in-page tab. 2 html files have been added in tests/visual/tabs in order to test this fix.

Only one element is added to the DOM but the _tabId function is called twice and next tab gets double-incremented id.

First tab called:

ui-tabs-2

Second tab:

ui-tabs-4

I've solved this by changing the _tabId function:

_tabId: function(a) {
        //PATCH ADDITION, if id set in data use that (when adding a tab), otherwise tabify will create two panels for 1 added tab
        if($.data(a, 'id')) {
            return $.data(a, 'id');
        } else {
        return a.title && a.title.replace(/\\s/g, '_').replace(/[^A-Za-z0-9\\-_:\\.]/g, '') ||
            this.options.idPrefix + getNextTabId();
        }
    }

And in the add function adding the following line:

add: function(url, label, index) {
        if (index === undefined) {
            index = this.anchors.length; // append by default
        }

        var self = this, o = this.options,
            $li = $(o.tabTemplate.replace(/#\\{href\\}/g, url).replace(/#\\{label\\}/g, label)),
            id = !url.indexOf('#') ? url.replace('#', '') : this._tabId($('a', $li)[0]);
        //PATCH ADDITION, set id
        $.data($('a', $li)[0], 'id', id);
        $li.addClass('ui-state-default ui-corner-top').data('destroy.tabs', true);

        // try to find an existing element before creating a new one
        var $panel = $('#' + id);

Just ran into this bug, quite a pest.

I solved this by changing only the add function (removed lines with // ):

    add: function( url, label, index ) {
        if ( index === undefined ) {
            index = this.anchors.length;
        }

        var self = this,
            o = this.options,
            $li = $( o.tabTemplate.replace( /#\\{href\\}/g, url ).replace( /#\\{label\\}/g, label ) );

        //id = !url.indexOf( "#" ) ? url.replace( "#", "" ) : this._tabId( $( "a", $li )[ 0 ] );

        $li.addClass( "ui-state-default ui-corner-top" ).data( "destroy.tabs", true );

        // try to find an existing element before creating a new one
    //  var $panel = $( "#" + id );
    //  if ( !$panel.length ) {
    //      $panel = $( o.panelTemplate )
    //          .attr( "id", id )
    //          .data( "destroy.tabs", true );
    //  }
    //  $panel.addClass( "ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide" );

        if ( index >= this.lis.length ) {
            $li.appendTo( this.list );
            //$panel.appendTo( this.list[ 0 ].parentNode );
        } else {
            $li.insertBefore( this.lis[ index ] );
        //  $panel.insertBefore( this.panels[ index ] );
        }

        o.disabled = $.map( o.disabled, function( n, i ) {
            return n >= index ? ++n : n;
        });

        this._tabify();

        if ( this.anchors.length == 1 ) {
            o.selected = 0;
            $li.addClass( "ui-tabs-selected ui-state-active" );
            $panel.removeClass( "ui-tabs-hide" );
            this.element.queue( "tabs", function() {
                self._trigger( "show", null, self._ui( self.anchors[ 0 ], self.panels[ 0 ] ) );
            });

            this.load( 0 );
        }

        this._trigger( "add", null, this._ui( this.anchors[ index ], this.panels[ index ] ) );
        return this;
    },

Until it is fixed, I am using the following workaround. It seems to work for me. If you expect the active div to be empty, then it wont work.

tabContainer.bind("tabsload",function(){
  $(this).children('div.ui-tabs-panel:empty').addClass('ui-tabs-hide');
 });

I just found out the hard way this bug exists, but I also stumbled upon a workaround.

The point is, if you it like this:

<div id="tabs">
   <ul>...</ul>
   <div id="tab-1">
   </div>
   ...
   <div id="tab-new">
      ...content...
      <script>
      $(function() {
   	$("#tabs").tabs( "add" , "#tab-new" , "New added tab" );
      });
      </script>
   </div>
</div>

Then you'll get 2 "new added tab"'s in the tabbar!

If you do it like this:

<div id="tabs">
   <ul>...</ul>
   <div id="tab-1">
   </div>
   ...
   <div id="tab-new">
      ...content...
   </div>
   <script>
   $(function() {
      $("#tabs").tabs( "add" , "#tab-new" , "New added tab" );
   });
   </script>
</div>

Then it's ok. (the <script> is outside of the div that becomes a tab-panel)

It looks like the content of the tab is "executed" again when adding it like a tab.

This looks to be fixed with the new tabs rewrite: http://jsfiddle.net/petersendidit/rmEYT/17/

#7570 is a duplicate of this ticket.

Hi,

I'm curious about the status of this bug. I have latest jQuery UI @ 1.8.16 on the bug still exists. I would be willing to switch to the "tabs rewrite" but where is that? I'd rather not go into the source and fix it to stay future compatible. The "Fixed in 1bacdec6be7e9d543224c69344041aaccde059c0" has a tooltip that says "No changeset 1bacdec6be7e9d543224c69344041aaccde059c0 exists in the repository." so I'm wondering if this got lost somewhere by mistake?

Thanks for the help!

The milestone says 1.9, so this is not in 1.8.16. You need to use master to get this fix.

is there a minified version of the pre-release?
