Dynamic change of class of <TR> with Jquery -

-

this first post, , first please forgive me poor english.

i have problem can't fix:

i have <table> of questions,

  1. the first question visible (class:visible), others hidden (class:hidden)

            $(document).ready(function(){         $('.hidden').hide();

  2. when people click on first question, want second question appear (and first question turn grey, using 'done' class).

$('.visible:not(.done)').click(function(){                  $(this).addclass('done');                  $('.hidden:first').toggle(500).removeclass('hidden').addclass('visible');             })

the first question done (class:done) , 2nd question should 1 react click(), , on... doesn't work: other <tr> appear when click on 1st <tr>.

can give me hand on problem ? thank you.

since adding classes dynamically , click event handler class selector based have use .live() event.

$('.visible:not(.done)').live("click", function(){      $(this).addclass('done');      $('.hidden:first').toggle(500).removeclass('hidden').addclass('visible'); });

working demo

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...
