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?
