Question

How to remove a class that has been appended to a div id? Earlier I appended a star to a label,when a checkbox is click.

 $("<span class='req'><em> * </em></span>").appendTo("#displayPanel #labelstr"+div_id);

Now,if the same checkbox is clicked again I want to remove that star.
I know there is a remove() option, but what is the proper code for it?
Please guide me.

By the looks of it, you’re not trying to remove a class which would be the removeClass() command, but instead need to remove a child element from a <div>

You could do

$("#displayPanel #labelstr" + div_id + " span.req").remove(); 

to remove the child span element with class ‘req’ from the <div>.
