Wow there sure are a lot of solutions here. If the popup js fails - popups are blocked If(popup & popup.chrome_popups_permitted & popup.chrome_popups_permitted() = true) Var timer = setTimeout(on_load_test, 60) Here's the code I use for cross-browser detection, without the Chrome part. It's not perfect, but it should work at least 95% of the time. I think the best thing you can do is wrap your test in a setTimeout() and give the popup 3-5 seconds to complete loading before running the test. (in fact, i believe your popup test code above won't work for safari.) The danger in this is that Safari detection works in a conflicting way: the popup's DOM will never be ready() in Safari because it'll give you a valid handle for the window you're trying to open - whether it actually opens or not. If you were using a Javascript Framework like jQuery (or something similar), you could use the ready() event (or something similar) to wait for the DOM to load before checking the window offset. You could test this easily by adding a very large graphic to the popup (clear your cache first!). Or else it might be when everything (images, outboard CSS, etc.) has been loaded. Well the "magical time" you speak of is probably when the popup's DOM has been loaded. In other words, I'm still no closer to figuring this out. After some magical period (a couple of seconds in my testing), the location and size information is returned as the correct values. Unfortunately, it also returns the same values even if the popup is actually opened for an unknown amount of time. Google Chrome returns all position and height values as 0 when the popup is blocked. Is there a way to do this without browser sniffing?Įdit: I have now tried making use of newWin.outerHeight, newWin.left, and other similar properties to accomplish this. I try to avoid browser sniffing in favor of feature detection. What I would like to do is be able to tell if the popup was blocked by Chrome's popup blocker.
Of course, the test is working to an extent since Chrome doesn't actually block the popup, but opens it in a tiny minimized window at the lower right corner which lists "blocked" popups. The "POPUP BLOCKED" section is never reached when the popup is blocked. If(!newWin || newWin.closed || typeof newWin.closed='undefined')īut this does not work in Chrome. Here's the basic test: var newWin = window.open(url) I am aware of javascript techniques to detect whether a popup is blocked in other browsers (as described in the answer to this question).
