You should call $(this), not $('this')

• $(this) wraps the object referred to by this inside a jQuery object,
• $('this') will traverse all of your document looking for html nodes tagged this (much like $('div') will look for html nodes tagged div); since there isn't any, it will select an empty list of nodes.

( there also was a typo, calling .hide(") instead of .hide() )

Try this way:

$(".show").click(function (e) { //<-----pass the event here
   e.preventDefault(); //<--------------stop the default behavior of the link
   var link = $(this).attr('href'); //<-remove the quotes $(this)
   $(link).show();
});

$(".close").click(function () {
   $(this).closest("div.popupbox").hide(); //<----use .hide(); not .hide(");
});

You should use preventDefault() in these cases to stop the jump which take place when a link get clicked.
