Question

Right now I have a dynamic string that assigns it’s values to a particular div class.
Output looks like this

  <div class="12923"></div>

I want to find that ‘randNumber’ div, then check if it has another class ‘x’

Currently what I have now doesn’t work:

  var randNumber = 12923

  var lookingForYou = $$('.'+randNumber);
  if (lookingForYou.hasClass('XCLASS')){alert('XCLASS FOUND!');}

Answer 1

$$ returns an array of all matching elems. Not sure if you can do a hasclass on an array. Might have to do a .each() then do it. Try $(‘body’).getElement(‘.’+randNumber).hasClass(‘XCLASS’) this way you grab 1 elem if you don’t want to mess with the array.
