Just set the className attribute of the real DOM element to     nothing        item   0  className          the real DOM element is at  0    Edit  Other people have said that just calling removeClass works - I tested this with the Google JQuery Playground  http   savedbythegoog appspot com  id ag5zYXZlZGJ5dGhlZ29vZ3ISCxIJU2F2ZWRDb2RlGIS61gEM     and it works  So you can also do it this way       item   removeClass

Let s use this example  Maybe you want the user of your website to know a field is valid or it needs attention by changing the background color of the field  If the user hits reset then your code should only reset the fields that have data and not bother to loop through every other field on your page       This jQuery filter will remove the class  highlightCriteria  only for   the input or select fields that have this class     form find  input select   filter function          if    this value   amp  amp     this name                   this id  removeClass  highlightCriteria

You can just try    document  ready function           body   find   item   removeClass          If you have to access to that element without class name  for example you have to add a new class name  you can do that     document  ready function           body   find   item   removeClass   addClass  class-name          I use that function in my projet to remove and add class in a html builder  Good luck

item   removeClass      Calling removeClass with no parameters will remove all of the item s classes     You can also use  but is not necessarily recommended  the correct way is the one above        item   removeAttr  class        item   attr  class            item   0  className         If you didn t have jQuery  then this would be pretty much your only option   document getElementById  item   className

Since not all versions of jQuery are created equal  you may run into the same issue I did which means calling     item   removeClass    does not actually remove the class   Probably a bug   A more reliable method is to simply use raw JavaScript and remove the class attribute altogether   document getElementById  item   removeAttribute  class
