$('#tag1').removeClass('div.domtab div');

but it still not working. clear:both cause all my div not float left.....

Considering your markup is like:

<div class="domtab">
  ...
  <div id="tag1"></div>
  ...
</div>

You can remove the class by

$('#tag1').closest('.domtab').removeClass('domtab');

try $('#tag1').removeClass('domtab');

You just missed out the line that is actually correct.

$('#tag1').removeClass('domtab');

The code above should do the trick.

The reason the above answers are correct, is because this method specifies "Class" in it's name, implying that it is ASSUMED you are giving it a valid class name. Being as "." implies a class, this becomes a redundancy.

Thus, when using "removeClass" a "." should not be used.
