javascript - Can I change a value in parent page's JS from iframe's JS? -

-

I have a page with 3 iframes and this page loads JS files containing 

  Var stayFifty = new boolean (wrong);

And this function, which changes on the basis of this boolean

On this page, I have an onclick function defined in an iframe 

  toggle = function () {parent.stayFifty = new boolean (! (StayFifty.valueOf () )); }; Added to an IMG tag with  

  onclick = "toggleFifty ();"

But when I click on the IMG tag, the togglefactory function does not seem to be in the fire. I believe that something to do with this is how the togglefactive function is trying to remain frozen. Fuzzy Variables Can anyone explain how to fix this issue and a little bit about the scope of the scope?

I tried to use the information from it but it seems that I do not understand anything.

When you change the value of the stayFifty variable, then the original < / Code> Do not Remember

Toggle = Function () {parent.stayFifty =! Parent.stayFifty; };

BTW, note that you do not need to use Boolean constructor while working with Boolean variables, and when you declare that you can use it: 

  / / stay on your parent's pageFifty = false;

c# - How to capture HTTP packet with SharpPcap -

-
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.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
