Question

How can I unset the current element from this “elems” array if it meets a certain condition?

var elems = $('input, select, textarea', this);

elems.each(function(){

  if($(this).attr('name') == 'something') {
    // unset `this` from elems ??
  }

});

I did a console.log on it and it doesn’t appear to have keys…

You can use the filter() function, which constructs a new jQuery object of those which returned true from the predicate function.

var elems = $('input, select, textarea', this);

elems = elems.filter(function(){

  if($(this).attr('name') == 'something') {
    return false;
  }

  return true;

});

This could of course then become;

var elems = $('input, select, textarea', this).filter(function(){
  if($(this).attr('name') == 'something') {
    return false;
  }

  return true;
});

For more info, see the filter() docs.
