remove-classes-from-an-element-with-jquery |
--description--
In the same way you can add classes to an element with jQuery's addClass()
function, you can remove them with jQuery's removeClass()
function.
Here's how you would do this for a specific button:
$("#target2").removeClass("btn-default");
Let's remove the btn-default
class from all of our button
elements.
--hints--
The btn-default
class should be removed from all of your button
elements.
assert($('.btn-default').length === 0);
You should only use jQuery to remove this class from the element.
assert(code.match(/btn btn-default/g));
You should only remove the btn-default
class.
assert(
code.match(
/\.[\v\s]*removeClass[\s\v]*\([\s\v]*('|")\s*btn-default\s*('|")[\s\v]*\)/gm
)
);
