Your getElementById is looking for an element with id  myclass   but in your html the id of the DIV is showhide  Change to    lt script gt  function changeclass      var NAME   document getElementById  showhide    NAME className  mynewclass       lt  script gt    Unless you are trying to target a different element with the id  myclass   then you need to make sure such an element exists

Just using this will add  mynewclass  to the element with the id myElement and revert it on the next call    lt div id  showhide  class  meta-info  onclick  changeclass this    gt   function changeclass element          element  toggleClass  mynewclass        Or for a slighly more jQuery way  you would run this after the DOM is loaded    lt div id  showhide  class  meta-info  gt       showhide   click function           this  toggleClass  mynewclass          See a working example of this here  http   jsfiddle net S76WN

Another example is       myClass   on  click   function         var  this     this       if   this hasClass  show          this removeClass  show         else        this addClass  show

With jquery you could do to sth  like this  which will simply switch classes       showhide   click function           this  removeClass  myclass          this  addClass  showhidenew          If you want to switch classes back and forth on each click  you can use toggleClass  like so       showhide   click function           this  toggleClass  myclass          this  toggleClass  showhidenew

For a super succinct with jQuery approach try    lt div onclick    this  toggleClass  newclass    gt click me lt  div gt    Or pure JS    lt div onclick  this classList toggle  newclass     gt click me lt  div gt

I would think this  http   jsfiddle net Skooljester S3y5p 1  should do it  If I don t have the class names 100  correct you can just change them to whatever you need them to be

I think you mean that you want want an onclick event that changes a class    Here is the answer if someone visits this question and is literally looking to assign a class and it s onclick with JQUERY   It is somewhat counter-intuitive  but if you want to change the onclick event by changing the class you need to declare the onclick event to apply to elements of a parent object   HTML   lt div id  containerid  gt       Text  lt a class  myClass  href       gt info lt  a gt       Other Text  lt div class  myClass  gt other info lt  div gt   lt  div gt   lt div id  showhide  class  meta-info  gt hide info lt  div gt    Document Ready    function              containerid   on  click    myclass  function e     do stuff              containerid   on  click    mynewclass  function e     do different stuff              showhide   click function    changeclass          Slight Tweak to Your Javascript   lt script gt  function changeclass                 myClass  myNewClass   toggleClass  myNewClass   toggleClass  myClass        lt  script gt    If you can t reliably identify a parent object you can do something like this     function            document  on  click    myclass  function e           document  on  click    mynewclass  function e          If you just want to hide the items you might find it simpler to use  hide   and  show
