Help! I have been into jQuery for about two weeks but I cannot solve
this problem.
I am trying to lop "bad" branches off the DOM tree. A bad branch is
defined as a branch that does not contain any appropriate anchor
address located in "keeplist". I have been able to lop off bad leaves
(VERSION 1). However, I have not been able to lop off "bad" branches.
VERSION 2 is supposed to lop off the bad branches, but instead it lops
off ALL branches. It is as if the "this" provided by "each()" refers
to the whole set of branches and not to the particular instance
supposedly provided by each().
VERSION 3 is also supposed to lop off the bad branches but as VERSION
2 it lops off ALL branches. "this" in VERSION 3 is obtained from the
second argument of each().
// VERSION 1 removes the leaf located down many levels
$(objectfoo).children().each(function(i){
$(this).find('a').not(keeplist).remove();})
// VERSION 2 supposed to remove bad branches
// instead removes ALL branches
var this2 ;
$(objectfoo).children().each(function(ichild){
this2 = this ; // buffer
if($(this2).find('a').not(keeplist)){$(this).remove();}})
// VERSION 3 supposed to remove bad branches
// instead removes ALL branches
var thischild2 ;
$(objectfoo).children().each(function(ichild, thischild){
thischild2 = thischild ; // buffer
if($(thischild2).find('a').not(keeplist)){
$(thischild).remove();}})
