1 pointIf $(this).attr('id') returns the correct ID, then this (and the jQuery-wrapped $(this)) refer to the same element. There's no reason to get the ID from the element, then get the element again. You already have it, you're getting the ID from it.
1 pointYou could also use $(this) to refer to each element, instead of getting the ID of $(this) and then looking up the same element.
1 pointYou're telling to find an element with the ID "podType". If you want to use the value of the variable, you need to specify that. $('#' + podType)
