javascript - Add class to all elements which have a certain class when clicked on -

-

i add class named "group" elements have class "someclass" - , e.g.:

<div class="someclass">sometext</div> <div class="someclass">someothertext</div> <div class="someotherclass">somemoretext</div> <div class="someotherclass">somemoreothertext</div>

should become following if user clicks on div containing class "someclass":

<div class="someclass group">sometext</div> <div class="someclass group">someothertext</div> <div class="someotherclass">somemoretext</div> <div class="someotherclass">somemoreothertext</div>

if user clicks on div containing "someotherclass" should added class "group".

i tried following jquery - unsuccessfully:

$("#someid").live("click", function() {         var selectedclass;     selectedclass = $(this).attr('class');      $('.'+selectedclass).addclass('group');     //...followed more jquery... });

i tried luck with:

$("#someid").live("click", function() {         $(this).attr('class').addclass('group');     //...followed more jquery... });

...which didn't work either :(

you ought take account possibility of divs having more 1 class -- happen whenever div clicked twice in row:

​$('div').on('click',function(e) {     var cl = $(this).attr('class'),         carr = cl.split(/\s+/);     (var i=0; i<carr.length; i++) {         $('div.'+carr[i]).addclass('newclass');     }; });​​​​​
