JSON jQuery PHP -

-

I do not understand one thing if I am using AJAX in PHP using JSON data in jQuery (key-value -Jodi), so which one should I use?

  • $ Get
  • $ Post
  • $. GetJSON

Do I need to use getJSON if I want to use json_encode in a PHP file? But if I want to send with the post (there is no postJSON )?

And one more thing:

I wrote a PHP file: / P>

In the jQuery file: 

  $ .getJSON ("php.php", {value: "value"}, function (data) {alerts ( Data. Firstname);});

Why does not this work?

The problem lies in the line with PHP: 

  returns $ Jsonstring;

You should echo it instead: 

  $ jsonstring echo;

The method to use the jQuery method, I suggest that $ GetJSON () If you can return the pure Jason string it depends on actually using it.

$ When using GetJSON () , your server file should return a JSON string. Thus echoing the string returned by json_encode () $. GetJSON () will be the method to take in response.

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...
