javascript - Returned AJAX array not being copied to array -

-

I have a simple AJAX function that uses jQuery to return an array of 300 test objects from a database.

This data has been copied to a JS array. The code fragment looks like this:

retrieve star locations to display on page $ .getJSON ("stars.php? Jsoncallback =?", Function (data) {for (Var x = 0, xx = data.length; x & lt; xx; x ++) {// planetary array [x] = new planet (data [x] .xpos, data [x] .ips); // Does not work either. (New Planet (data [x] .xpos, data [x] .ypos));}}); {// var i = 0, ii = planetArray.length; i & lt; ii; i ++) {// display data}

Firebug says that Planets around. Long is zero. Planet Constructor looks like this: 

  function planet (x, y) {this.x = x; this. Y = y; }

I think this is a scoping issue, but I can not seem to find it. Creating a new object in other languages ​​means that it exists on the heap and avoids the scope, but here it seems that disappears in ether.

How can I return an array and push it for use in my own array later (or in any other function)?

AJAX request happens asynchronously - you are not waiting for data before you Try and display

Move the display code to the callback and it should work.

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

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option.
