html - The proper way to handle popup closing -

-

I am looking for a close event for popup. I've got one, but I need it for HTML.

The property has closed in the popup. 

  & gt; & Gt; & Gt; Var popup = open ('http://example.com/', 'popup', 'height = 400, width = 500'); & Gt; & Gt; & Gt; Popup.closed false

Well, I can do it. 

  function open_popup () {var popup = open ('http://example.com/', 'popup', 'height = 450, width = 450'); Var timer = setInterval (function () {if (popup.closed) {warning ('popup off!'); Clear interval (timer);}}, 500); }

I tested it on Chrome 4.0.249.27, Opera 10.10, Safari 4.0.4 and Firefox 3.5.5. All work is fine.

But Set Interlude Me Distress Is It Ugly Is A Better Way To Do It?

Update: I use Popup for authentication dialog (in fact, oAuth). I want to send some messages after the popup is closed (via post message).

Page inside popup from any other domain. Therefore, I can not add any event ( unload ) due to security restrictions.

Can not use IFrame due to IFrame buster script. Therefore, I can not use any fancy jQuery model communication.

I can not edit some inside the popup.

You want to look at the unload event, but take a look

Edit : As you have said that you can not edit anything inside the popup, there is actually no option left. I believe your current SetInterval code fixes the job You should ask yourself if the real-time address of popup ending is very important 500 milliseconds The d-timer will certainly not weaken any resources or bring any computer to its knees.

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
