Are there side effects of using Javascript non-attached iframes? -

-

i use non-attached iframes in code send commands webcams:

var frm = document.createelement('iframe');                                                                                                                                                     frm.style.visibility = 'hidden';                                                                                                                                                                frm.style.display = 'none';                                                                                                                                                                     frm.src = "http://192.168.200.66/command=27";

notice, did not "document.appendchild(frm)".

this works, iframes send commands cam expects , i've seen no problems can find no documentation or examples of such usage.

are there side effects or problems using iframes way?

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
