Spry Tabbed Panels 2 - Remember Last Tab

Nov 16, 2010 8:37 AM

Using the Spry UI Tabbed Panels 2, has anyone found a way for the page to remember which tabbed was last viewed?

 

I can see that I can use the showPanel() method to set the panel, and I can use the getCurrentTabIndex() to retrieve the current tab index, but I am not sure what to do with them next.

 

I am thinking about maybe setting a cookie with the current tab index, but I don't know what to attach the onclick event to. Should I use a spry selector to add the onclick attribute to the a tag that is automatically generated?

 

Does anyone else have any clever ideas?

 

Cheers,


Steve

    Hi Steve,

     

    Have a look here http://go.spry-it.com/cookie with thanks to Arnout

     

    (the site was down at the time of posting, please be patient)

    Hi Ben,

    Thanks for the link. I had found another link to Arnouts Spry Cookie but assumed that since the link was dead that it was no longer available. I have emailed Arnout asking for the code, but not heard anything yet. After emailing him I found another site using the code so lifted it from there. Sadly I have not been able to get it to work with Spry UI yet. I will continue to try to get it working, I am not beaten yet!

     

    Cheers,

     

    Steve

    Once I found Arnouts correct SpryCookie.js I then managed to come up with this (with some help from another forum post):

     

    var cookie = Spry.Utils.Cookie("read","panel");
    TabbedPanels2.showPanel(cookie ? parseFloat(cookie) : 0)

     

    Spry.Utils.addUnLoadListener(function(){
        Spry.Utils.Cookie('create','panel',TabbedPanels2.getCurrentTabIndex() );
    });

     

    Not sure what has happened to Arnouts page, maybe his site is suffereing from the same problems that my servers are today, multiple routing issues in the UK. Anyone else having issues today?

     

    Cheers,

     

    Steve

    Next question

     

    How do I turn this into a plugin? I am sure others would benefit from being able to do this. Making it into a plugin would make it simpler to implment.

     

    Cheers,

    I have been searching for an answer for this for sometime now.  The http://go.spry-it.com/cookie  is not working.  Any help/suggestions.  I want to go to the last tab looked at after a page refresh or change.  Any help would be appreciated.

    Thanks Gramps... I found your previous post to this before as well.  I am just going nuts and know the cookie is not reading somewhere in this part of the code:

     

    var cookie = Spry.Utils.Cookie('read','tabbedpanels');

    var TabbedPanels1 = new Spry.Widget.TabbedPanels("TabbedPanels1",{defaultTab:cookie ? cookie : 0});

    Spry.Utils.addUnLoadListener(function(){

              Spry.Utils.Cookie('create','tabbedpanels',TabbedPanels1.getCurre ntPanelIndex());

    });

     

    I found another post that tweaked it some to:

    var TabbedPanels1 = new Spry.Widget.TabbedPanels("TabbedPanels1", { defaultTab: cookies ? parseFloat(cookies) : 0 });

    but that was no good and made the whole tabgroup not work.

     

    The next question is... why am I using Spry?  LOL.  Man I would like to solve this issue.
