Check if a class exist within a group of selected elements

Question

I have a group of rows selected and I am now trying to determine whether or not they contain a specific class.

I have tried it with hasClass without success as well as with find:

var group = $('table').find('[data-group="group1"]');

//this doesn't work, it always enters in the condition
if(group.find('.active')){
    alert("Founded?");
    group.addClass('green');    
}

I have also tried it with if(group.find('.active').length) but still not getting the correct result:

Answer 1

You can do this with hasClass method http://api.jquery.com/hasClass/

if(group.hasClass('active')){
...
}

If you tried this :

if(group.hasClass('.active')){
...
}

It certainly won't work, note the difference with the "."
