Jquery UI Modal Dialog Confirmation, Return Value

well lets start by the fact that u cant, the modal is a void, it doent return anything.
but then again god gave the JS creators the though to give us Callbacks!! problems solved!
just make ur "big" function a 2-3-x part.

lets start with the confirm code, I did it very generic and u can always add/remove:
　

function custom_confirm(output_msg, title_msg, okBtnText, cancelBtnText, ok_callback, cancel_callback) {
  if (!title_msg)
      title_msg = 'Alert';
  $("<div></div>").html(output_msg).dialog({
      title: title_msg,
      resizable: false,
      modal: true,
      buttons: [{ 
          text: okBtnText,
          click: function () {
             $(this).dialog("destroy"); 
             if (ok_callback){
                 ok_callback();
             }
          }
       }, {
          text: cancelBtnText,
          click: function () {
             $(this).dialog("destroy");
             if (cancel_callback){
                 cancel_callback();
             }
          }
      }]
  });
} 

the Callbacks r just simple functions like:
function myOkCallback() {
   alert('I DID IT!! I DID A CALLBACK IN JS!!');
}
and more Callbacks for each extra button, so u have the calling function and the callbacks, like with ajax.

p.s. to us noobs:
custom_confirm(output_msg, title_msg, okBtnText, cancelBtnText,
function() { some code... }, function() { some code... })

    I would have written:
    if(ok_callback) ok_callback()

    And same for cancel callback

    This way you have "overloads" without callbacks

OverTheWire[.com] Natas Walkthrough - JUST HINT, NO SPOILERS

game portal: http://overthewire.org/wargames/natas/ PASSWORDS for each level are stored in /etc/natas_webpass/natasX I made this walkthrough for people like me, i needed some help, but didnt want the spoiler, so here i will give you all the information needed to pass each level, yet not the solution. For levels needed custom web request i made a different post for powershell and javascript  with how-to's, since is a piece of learning for itself, and also for those of us that play at work and have only powershell at their hands. Although its not a complete spoiler there, its quite most of the solution so try yourself 1st. Natas The Natas game is from basic to advances web hacking. Every few levels is about whole new exploitation (with some harder ones doing comeback later), so a lot of learning. If you're new, you're the reason i am writing so much even for the 1st level, just please google EVERY topic you see, since in the following levels i assume you know the

Asp.Net Ending Response options, Response.End() vs CompleteRequest()

this blog is for any1 who get the ThreadAbortException when caling Response.End(), and then tried the other options such as HttpContext.Current.ApplicationInstance.CompleteRequest() and found out that there was no replacement. i'll start with the bottom line: if you want to stop right now your response and send it as is you dont have any other option other than Response.End(), period and it's the right thing to throw that EX in that case. the answer is its because there is the "HTTP pipeline" and the "Asp.Net pipeline", and CompleteRequest() cuts the HTTP pipeline but not the Asp.Net one so everything that is from handlers forwars (including all page events) continues but your part, the asp one, stays in your hands so that no information will be lost, so ur suppose to manage your code currectly, since information lost is really a bad thing, although in most cases we use Response.End() we know what we are losing and we want it. see this short article ab
