I have read all posts about how to detect that url have changed to new page and trigger the event handler then eg.
function aidLogout(evt) { if(evt) { /* maybe via analyse of evt object i can detect the close of the browser window */ } if(window.event) { /* maybe via analyse of window.event object i can detect the close of the browser window */ } var i = new Image(); i.src = "aidlogout.asp?uid=1562&SessionID=ABCDEFGHIJKLMNOP" } /* assuming that aidlogout.asp will return nothing or empty image */
window.unload = aidLogout; /* or via if(window.addEventListener) { window.addEventListener("unload", aidLogout, false); } else if(window.attachEvent) { window.attachEvent("unload", aidLogout); }
PS i know about super Gecko onclose event which fires when browser window is closed, but i could not find such method in IE.
How can Javascript code detect if a user has been authenticated to see a page, that is, if he has entered a username and password for HTTP authentification to see the current page. Possibly that can be determined from the HTTP request header, but how to access this data for the current page in Javascript?
Plus: how can it detect if the current page is encrypted? Is looking at the protocol ( https:// ) enough to determine this?
I need it to work in a Firefox extension and why I need this is because I don't want to process pages that may contain sensitive information.
I have a page that has links to other pages. I want to be able to detect when the user has clicked on Back (or typed Backspace) to move back to my page. Is this possible?
I currently use Google's and Quantcast's javascript includes on my site. I want to do the same thing for users of my site except on a much easier level. I want users to include a javascript that detects the URL of the page where the script is included... Should be easy but I don't know where to start.
Is there any way that an Apache server can recognise that a users browser has changed from your web site to another site. ie. is there a way of executing a CGI based on when the address bar no longer has your FDQN. Would this be via Javascript [if possible?] or ???
I need to take some action when the user leaves my website. By leave I mean one of the following two cases:
1) Closes the browser 2) Goes to some other site (different domain)
Is there a way to detect this? I know that the event onbeforeunload and onunload gets fired when the user leaves the page, but these also get fired when the user leaves page A in my site and just goes to page B in my site. I don't want to alter every link within my site to fire the onclick event and in such event to "remember" in a JavaScript variable this is a navigation within my site. I am looking for some clean solution if one exists. For example, is there a way to get the information in the DOM where the user is going to when the onbeforeunload or onunload are fired?
my page allows the user to enter a number in a text box and a search request is sent to the server (if the user stops typing for 200ms) using AJAX. The following is the desired behavior.
(1)User starts typing a number in the text box. As the user is typing, no search requests are sent to the server.
(2)Once the user stops typing (i.e. no key events for 200 ms), use $.post() to execute a search.What is a good way to detect that the user hasn't typed anything for 200 ms?Is there anything in JQuery that I can use?
I got a textarea and I need to detect instantly if user input is a chinese character or not. View this message in context: [URL] Sent from the jQuery General Discussion mailing list archive at [URL].
Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?
I'm creating an AJAX user validation so that when a user types in a username, it checks it in the database to see if it exists. I want it to execute after the user finishes typing. I've tried using: $("#username_field").keyup(function(){ which works, but I don't want a query executed every time the users presses a key. I was wondering if there was a better way to do it. Meaning I what the check to be preformed after the user finishes typing.
is it possible to track whether user is typing in the browser's address bar or aside google search box ( which appears in most of the browsers besides address bar)? if yes, I would like to know HOW? references are welcome.

Imagine a wife has signed on to a web site in a browser tab. She does not sign off and walks away to do something else. Her husband sits at the computer and seeing her signed on, opens a new tab and tries to sign on to the same site. I need to automatically sign the wife off when this happens so as to avoid confusion later regarding which session is active.

how I might use JavaScript to detect the overflow of text in a DIV. Currently, I have the CSS set to Code:
overflow:auto
However, having scroll bars are pretty tacky. Instead, I'd like to be able to detect the overflow, which would then add a small <a href> link that says "More."
I was wondering how I could detect if a user has ad-block or ad-sweep or any other ad blocking ad-ons for that matter. I want to be able to detect this because if they do have ad-block I want to display an image in the place where the blocked ads are. That way theres not all this empty space
