To match the title of this question  the value of the id attribute is  var myId     this  attr  id    alert  myId     BUT  of course  the element must already have the id element defined  as   lt option id  quot opt7 quot  class  select continent  value  7  gt Antarctica lt  option gt   In the OP post  this was not the case   IMPORTANT  Note that plain js is faster  in this case   var myId   this id alert   myId      That is  if you are just storing the returned text into a variable as in the above example  No need for jQuery s wonderfulness here
