Problem using onbeforeunload in JQuery or Javascript

Good Day All

i am opening a Popup and i want to bind the "onbeforeunload" to the popup that if someone clicks on the close button in the window or close button in the page , the event should fire a javascript function that is on the page that opened the popup.

JavaScript

function ProcessPayment(Downloadurl)
     {


         var url = "http://XXXX.com/cccc_ccccc/2938dc870cd394?tc_id=210&tc_45f=50.0&sig=fc5cbfe44230";
         var popupWindow = window;

popupWindow.onbeforeunload = function () {
             if (Downloadurl != "") {
                 $.fileDownload(Downloadurl)
               .done(function () { alert('File download a success!'); })
               .fail(function () { alert('File download failed!'); });
             }
             else {
                 alert("No URL found");
             }
         }

         //open the Popup window
         popupWindow.open(url, 'popUpWindow', 'height=400,width=500,left=10,top=10,resizable=no,scrollbars=yes,toolbar=no,menubar=no,location=no,directories=no,status=yes')
          //bind the event so that when a user close the windown , we download the file

when i try this nothing happens the event does not get work and no error in the browsers console

Thanks

Please do not use pop ups!

Popups are a very ugly way of shoving some data into the users face, in a way he probably doesn't like and didn't ask for. The only thing that should open a new window or tab is me middle-clicking (or right-clicking) a link. Everything else should stay in the existing window.

hi Nicholas

I am building a mobile app using cross-platform mobile development toolkit, so this is something that gets popup when a third-party payment is required.

Our app uses popups all the time. It works like Microsoft CRM. When you double-click a grid record we open the record maintenance in a popup.

Popups have their place but they did get a bad name because of people misusing them.

You may read here to understand unbeforeunload - it's definitely not a standard JavaScript event...

I'm pretty sure that event has to be in the window itself, you can't attach your own. I could be wrong though.

Also, popupWindow.open() can be done modally so you can get the return value from it. If the return value is null, depending on the window, that could be the indication you are looking for.

I am using kendoui un MVC.
Datepicker has watermark, if date is blank val()='' works fine in FF and Chrome but not in IE11.
In IE11 it shows the watermark value

any suggestion how to overcome this issue?

it was something like this
var fromDate = $("#start").val().trim();

now i am using regex and it is working fine
fromDate.match(/^([1-9]|1[012])[- /.]([1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d$/))

Obfuscated script (likely malware)

What does following script do:

(function() { var b=window,f="chrome",g="jstiming",k="tick";(function(){function d(a){this.t={};this.tick=function(a,d,c){var e=void 0!=c?c:(new Date).getTime();this.t[a]=[e,d];if(void 0==c)try{b.console.timeStamp("CSI/"+a)}catch(h){}};this[k]("start",null,a)}var a;b.performance&&(a=b.performance.timing);var n=a?new d(a.responseStart):new d;b.jstiming={Timer:d,load:n};if(a){var c=a.navigationStart,h=a.responseStart;0<c&&h>=c&&(b[g].srt=h-c)}if(a){var e=b[g].load;0<c&&h>=c&&(e[k]("_wtsrt",void 0,c),e[k]("wtsrt_","_wtsrt",h),e[k]("tbsd_","wtsrt_"))}try{a=null,
b[f]&&b[f].csi&&(a=Math.floor(b[f].csi().pageT),e&&0<c&&(e[k]("_tbnd",void 0,b[f].csi().startE),e[k]("tbnd_","_tbnd",c))),null==a&&b.gtbExternal&&(a=b.gtbExternal.pageT()),null==a&&b.external&&(a=b.external.pageT,e&&0<c&&(e[k]("_tbnd",void 0,b.external.startE),e[k]("tbnd_","_tbnd",c))),a&&(b[g].pt=a)}catch(p){}})();b.tickAboveFold=function(d){var a=0;if(d.offsetParent){do a+=d.offsetTop;while(d=d.offsetParent)}d=a;750>=d&&b[g].load[k]("aft")};var l=!1;function m(){l||(l=!0,b[g].load[k]("firstScrollTime"))}b.addEventListener?b.addEventListener("scroll",m,!1):b.attachEvent("onscroll",m);
 })();

I found it embedded in a page which looks harmless...
[Edit]I guess it is the same type of hack which I experienced 1.5 years agon on my web site, but the hacker added some more obfuscation now. See Analysing an obfuscated malware script[^].[/Edit]

It's not obfuscated, but minified and it looks like a timing function, based on Google's library...

Thanks for your analysis. I hardly ever use JavaScript, so I rely mainly on context and experience. "minify" and "obfuscate" cause the same impression...

Re: Obfuscated script (likely malware)

Nicholas Marty25-Feb-14 4:17

minifying is just to decrease the size of the script and thus decreasing the time needed for loading it from the server
obfuscating the code is done to protect the code to some degree from beeing copied by others. You can't compile javascript into a binary form that prevents doing so (you can't compile any .Net applications in that regard neither) so in those cases obfuscation makes it harder to understand the code.

A small sample (consider this as a piece of pseudo code)

JavaScript

function foo() {
   // do foo
  var counter = 0;
  bar(counter);
}
function bar(var myParam) {
  // do something with myParam
  var somethingElse = myParam;
}

and obfuscate it to

JavaScript

function a() { 
   var b=0; 
   a(b); 
}
function a(var b) { 
   var c=b;
}

you don't really know what those function really do without having the full context of it, thus making it a lot harder to just copy a function out of the script "stealing" someone else's hard work.

So nothing shady about those (of course you could assume that malicious scripts will usually be obfuscated and minified to prevent user from easily detect what they are doing)

Re: Obfuscated script (likely malware)

Bernhard Hiller25-Feb-14 20:51

Thanks for this explanation. It was the context (faked entry in a log file) paired with past experience and the unreadability of that script which made me assume malware.
Though minifying scripts may be legitimate to decrease the still increasing enormous volumes of JavaScripts sent over the network with still decreasing "payload" of actual content, it makes distinguishing those scripts from intentiously obfuscated malware scripts extremely hard - thus actually causing security issues.
