javascript - Disallow window.opener from child window -


i'm opening popup page code this:

var w = window.open(url, "_self"); w.opener = null;

or this:

var anchor = document.createelement("a");   anchor.target = "_blank";   anchor.href = url;   var evt = document.createevent("mouseevents");   evt.initmouseevent("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null); anchor.dispatchevent(evt);

this works fine, problem document loaded in popup window has permission change location of opener window. works when document in popup different domain. has no permission read location allowed change location. don't want that. want popup disconnected main page.

window.opener.parent.location.href="http://example.com"; in child window change parent window url

is there trick can use break connection between opener window , opened window? ideally opened window should not know opened other window @ all.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
