use event.target to get the class value?

Question

i have a DOM element with class=\'tag\'.

i want to check if the class value is tag and alert a message if it\'s true.

i wrote:

    $(\"#thread\")         


        

Answer 1

you are using jquery's each method incorrectly. it takes two arguments, neither one of them is an event (that would respond to the target property). from the docs:

$.each([52, 97], function(index, value) { 
  alert(index + ': ' + value); 
});

See CMS's answer for the proper way of checking if elements have a given class name.
