Answer 1

There are several ways to do this. You can use map():

var ids = $("#container").children().map(function(n, i) {
  return n.id;
});

or each():

$("#container").children().each(function(n, i) {
  var id = this.id;
  // do something with it
});

etc.

Answer 2

you can use

attr('id')

Answer 3

$('div', $('div#container')).each(function() {
    console.log($(this).attr('id')); 
});

Answer 4

to get them as an array of strings

var ids = $.map($('#container div'), function(n,i) {
              return n.id
          });
