Help me optimize the if else in JavaScript (jQuery) -

-

Is it possible to shorten this code in some way: 

  var i = GetStringFromServer ('/ url'); If (i) {$ ('# div1'). Hide (); $ ('# DIV2') Show (). } And {$ ('# div1) .show (); $ ('# DIV2) .hide (); }

In C # I will do just that: 

  bool smth = GetBool (); _el1.Visible = empty; ! _el2.Visible = empty;

Is it possible to erase logic in JavaScript?

Update: Thanks for the good answer, I did toggle before asking myself, but what was confused was the method sign: 

  toggle (fn1, fn2);

I thought the function was expected to have some difficult callbacks, but apparently it was flexible enough to handle both plain boolean and callback.

UPDATE2: Thanks to the comments of Robert and Fabian, the truth finally got the answer. Toggles will always make visible or invisible on the basis of the logic of the bill.

If you toggle the boolean argument, this will apply to each matching element from the docs: < / P>

Toggle the set of all the elements matched based on the switch (all shows all the elements, hides all false elements).

In your case, you want: 

  $ ("# div1"). Toggle (! I); Turn on $ ("# DIV2") (i).

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
