how to close web page in the flash

i want to close the web page when user click the button in the flash.this is the code i used
public static function close():void{
// ExternalInterface.call("window.close()");
navigateToURL(new URLRequest("javascript:window.close();"),"_self");
}
this approach seems out of date nowadays. it only works for local page,use file:/// to access,but access it in a remote way,the code didn't give me a **,not even throw a security error.What do i suppose to do?

UPDATE:
This regretfully does not help with the firefox. The issue is not in actionscript, but in the way how the firefox handles the window.close() function. You can simply replicate this by trying to call window.close() directly from javascript without any actionscript. It is a security restriction. There are some related questions, answers and possible solutions here:
Close windows that were not opened by script using javascript
and here:
How can I close a window with Javascript on Mozilla Firefox 3?
END OF UPDATE
I am sure this is a security issue.
Have a look in the console, isn't there something similar to the following?
Scripts may not close windows that were not opened by script. # javascript:window.close();
I suggest to create a function in javascript which would close the window and call this function using external interface. Something like this:
JS:
function closeWindow() {
...
}
AS:
if(ExternalInterface.available) {
ExternalInterface.call("closeWindow");
}

stop the web page from loading programmatically

I want to create an extension to firefox using addon builder that
stops users from visiting a malicious website; When I see a URL that is
suspicious, I stop the page from loading and ask the user if he really
wants to visit the site. How could I implement that? I am expecting the functionality programmatically, so that I can make an extension.

if(site.is_malicious)
window.stop();

There is an event called beforescriptexecute supported my mozilla ..... Have a look , I think it will work the job for you. But what you desire can be done something like this:
var r=confirm("Are you sure you want to visit this site ?");
if (r==false) { window.stop(); }

You are creating a FF extension right? Why not use greasemonkey or so? You can execute a script BEFORE the page loads(on greasemonkey). when that script is called, you can potentially stop the pageload and throw an error message.

javascript failing with permission denied error message

I have a classic ASP web page that used to work... but the network guys have made a lot of changes including moving the app to winodws 2008 server running iis 7.5. We also upgraded to IE 9.
I'm getting a Permission denied error message when I try to click on the following link:
<a href=javascript:window.parent.ElementContent('SearchCriteria','OBJECT=321402.EV806','cmboSearchType','D',false)>
But other links like the following one work just fine:
<a href="javascript:ElementContent('SearchCriteria','OBJECT=321402.EV806', 'cmboSearchType','D',false)">
The difference is that the link that is failing is in an iframe. I noticed on other posts, it makes a difference whether or not the iframe content is coming from another domain.
In my case, it's not. But I am getting data from another server by doing the following...
set objhttp = Server.CreateObject("winhttp.winhttprequest.5.1")
objhttp.open "get", strURL
objhttp.send
and then i change the actual html that i get back ... add some hyperlinks etc. Then i save it to a file on my local server. (saved as *.html files)
Then when my page is loading, i look for the specific html file and load it into the iframe.
I know some group policy options in IE have changed... and i'm looking into those changes. but the fact that one javascript link works makes me wonder whether the problem lies somewhere else...???
any suggestions would be appreciated.
thanks.

You could try with Msxml2.ServerXMLHTTP instead of WinHttp.WinHttpRequest.
See differences between Msxml2.ServerXMLHTTP and WinHttp.WinHttpRequest? for the difference between Msxml2.ServerXMLHTTP.
On this exellent site about ASP you get plenty of codesamples on how to use Msxml2.ServerXMLHTTP which is the most recent of the two:
http://classicasp.aspfaq.com/general/how-do-i-read-the-contents-of-a-remote-web-page.html
About the IE9 issue: connect a pc with an older IE or another browser to test if the browser that is the culprit. Also in IE9 (or better in Firefox/Firebug) use the development tools (F12) and watch the console for errors while the contents of the iFrame load.
Your method to get dynamic pages is not efficient i'm afraid, ASP itself can do that and you could use eg a div instead of an iframe and replace the contents with what you get from the request. I will need to see more code to give better advice.

how can I force IE9 to "see" the most current javascript when using the debugger?

I'm using IE9 to debug a web app. I made some changes to the javascript after loading the page. I'm not able to get IE9 to stop on the new code. The message is "The code in the document is not loaded". I can set breakpoints when I'm not debugging, but they won't be valid when I start debugging. I'm using IE7 Browswer Mode, IE7 Document Mode.
Things I've tried:
close dev tools window, re-open
stop debugging, start debugging
Ctrl R in dev tools window (same as Clear Browser Cache button)
Ctrl R on the IE9 web page
Ctrl F5 on the Ie9 web page
Clear browser cache for this domain
Check (set) Always refresh cache from server
Next thing to try (I guess) would be closing IE completely. Is that the fix for this? If so, yuck. It takes me a couple of minutes to set the page up so doing that after every JS change really stinks. I can use FF4 to develop the JS, but the JS issue I'm seeing is specific to IE7 so I have to do it this way.
>> How can I get IE9 (running in IE7 mode) to reliably debug the most current JS from the server?

This issue wasn't related to caching etc. IE9 was hitting a script error (missing closing paren) in the new code and not allowing breakpoints anywhere in the script. IE seemed very quiet about the script error though. Anyway, fixing the script error fixed the issues with breakpoints / caching.

If you have access to the code:
In you javascript file reference add a query string, something like this:
<script src="Scripts/main.js?v=1" type="text/javascript"></script>
And every time you change in the js file change the v value to something else, like that the browser will feel that this is a new file and will get it.

Add this:
window.applicationCache.addEventListener('updateready', function (e)
{
if (window.applicationCache.status == window.applicationCache.UPDATEREADY)
{
window.applicationCache.swapCache();
if (confirm('A new version of this site is available. Load it?'))
window.location.reload();
}
}, false);
I found this solution somwhere in the Net. Sorry, but I don't remember the author. It works for me when I debug Web App with JavaScript in Visual Studio and use IE.

I found this question based on the "the code in the document is not loaded" error message. I'm not using IE7 document mode or any of that, just IE9.
Like jcollum, my issue wasn't related to caching.
I'm using MVC.Net, and someone had set up a piece of javascript to rely on a string in the ViewBag. I changed a couple things, and that ViewBag string disappeared, so the resulting javascript looked something like this:
if(!()) {
// Some code
}
Javascript died right here, and wouldn't process the rest of the code in the block. This was confusing, as it was still trying to execute javascript in a different set of script tags, but which relied on a variable set in the other block it wouldn't load.
So, basically, a syntax error was introduced via strange means, and the debugger refused to load some of the code which came after it. Another lesson on the dangers of ViewBag.

What are some methods to debug Javascript inside of a UIWebView?

I'm trying to figure out why something with Javascript isn't working inside of a UIWebView. To my knowledge, there is no way to set a breakpoint inside of XCode for a js file. No problemo, I'll just go back to 2004 and use alert statemen-- oh wait they don't seem to work inside of a UIWebView either!
The only thing I could think of is by exporting my HTML And JS files to my desktop and then just doing my debugging inside of Safari. And that works! But of course, the bug I'm fighting with in the UIWebView doesn't occur in Safari.
Are there any other ways for debugging inside of a UIWebView, or any tricks that I can use akin to using the old-school alert method?

If you're using iOS >= 6 and you have mountain lion (10.8) or Safari >= 6, you can just:
Open the application in the simulator (or your device in XCode >= 4.5.x).
Open Safari (go to Preferences -> Advanced and make sure "Show Develop Menu in Menubar" is on.
From the Menu-bar (of Safari) select Develop -> iPhone Simulator -> [your webview page].
That's it !

This query tops google, so worth linking to the remoteInspector hidden in iOS5 - by far the best way found so far to debug your UIWebViews - just conditional compile out before you send to Apple.

alert() certainly works for me.
However, you can also do lots of other things, like make your own DHTML alert that pops up in a layer. This can be nice because you can do multiple alerts to a single div, without stopping your app. You should also be able to write a stack trace to it (the stack trace is in the exception object, and you can always throw your own exceptions).
Alternatively, if running on the simulator your custom "alert()" could call into objective C, and display the string in the iPhone simulator's console window:
document.location.href = "http://debugger/" +
encodeURIComponent(outputString);
and on the objective C side:
//--------------------------------------------------------------------
- (BOOL)webView:(UIWebView*)webView
shouldStartLoadWithRequest: (NSURLRequest*)req
navigationType:(UIWebViewNavigationType)navigationType {
if ([[[req URL] host] isEqualToString:#"debugger"]){
// do stuff with [[req URL] path]
}
}
That said, I have an app that is heavy on the UiWebView / javascript stuff, and I tend to do most javascript dev in Chrome (simulating what is necessary from the iPhone environment)

I get the awesome way to debug UIWebView Or
SFSafariViewController.
I hope It will Help.
Step 1:
Open Safari VC In Your Mac (hahaha Don't make your face, If I am saying in your Macbook just follow this my steps)

Step2: Go at Safari preferences And Click on Advance. 

You will Get this setting on your MacBook Screen.
Now enable the Show to develop menu in menu bar.

 Now Your All work is done. 

Are you thinking I am kidding :P :P no man...


Step3: Run your application in Device or Simulator. (Don’t Think Just run )
And go in your application where you are opening your Webview or SFSafariViewController.
Till now you did not understand I know. Be cool and see my next step.

Step4: Open Safari In your MacBook and Click on Develop Option from the Menu bar. 

Did you get something your MacBook, iPad/ iPhone is Displaying Right?????


Step5: Its Done. click your device and click on URL New popup will come out like This.



Step6: what are you looking now its over here all the steps.
Now debug your Webpage on this console.
Be happy and enjoy your day while doing coding With a cup of tea or
Coffee.

I haven't tried this yet, but take a look at this Weinre
Looks very promising.

This is an old question. But I'll still like to share my two cents.
I have been using jsconsole.com for remote debugging. It's easy. Just include a script tag and use console logs to debug by printing. This can also be used for debugging on a real device.

Old question, but I think I found the best solution, in my case you need to debug uiwebview, but I had no access to the IOS app and only to the html content and I had to view some JS logs, I added the following code to load the light firebug JS and show it automatically:
calling it from JS
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'https://getfirebug.com/firebug-lite-debug.js';
document.head.appendChild(script);
or load it from html
<script type="text/javascript" src="https://getfirebug.com/firebug-lite-debug.js"></script>

You can set up a system like that used in PhoneGap to send messages from JavaScript to Objective-C and log from there. In a nutshell, they are setting document.location with a custom scheme and blocking that scheme in the delegate callback.
You can take advantage of the fact that a UIWebView is most of the delegates for a WebView. WebKit is technically undocumented for iPhone, but mostly the same as specified in the desktop WebKit headers, possibly including the WebScriptObject. I use this for debugging, but be sure to strip this code out before submitting to Apple.
To get a WebView from a UIWebView, implement a delegate method like -(void) webView:(id)inWebView didFinishLoadForFrame:(id)inWebFrame in a subclass of UIWebView. Call super if you use that one.
