JQuery :: Good Way To Detect That User Hasn't Typed Anything For 200 Ms?
Apr 24, 2009
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 currently have a bid of code:
(simplified)
$(function() {
$(window).bind('scroll',function(event) {[code]...
But I only need it to execute if the user hasn't scrolled for three seconds. I don't really have a clue how to go about this.

is there a way to determine whether a user clicked on a link vs typed in the url to get to a page? I'm trying to stop users from messing with GET forms (and i have to use them, POST wouldn't make sense in this case).

Are there any good web UI component libraries -open source or commercial - that you can recomment? They need to be cross browser compatible and have good documentation. Jquery UI is very good but limited in number of controls it offers. YUI is very verbose and very hard to use. extJs only other one I can think of. Any others you use and like?

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 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?

I understand that using
Code:
.parent(".class")
I can select the parent of the current element if it (the parent) has a class named "class". How can I select parents that don't have a certain class? Also, how can I select parents that don't have more than one class? Does the .parent() method allow to do this?

My workplace has a lot of people doing manual entry. I'm looking to provide some friendly automatic formatting of data as they type it. I have working code (thus far) but I want to ensure I'm doing things in a sane way (there's a surprising amount you can do insanely that still works Here's a function below that transforms a phone number - the worker enters the digits(only), the field reflects (and could also accept) the fully formatted version (e.g. (123) 456-7890 ).

Originally I had the following code. What it does is for a user to type the folder name of their choice and then after clicking submit a window will pop open and they will be taken to "C:folder" (assuming the user typed "folder" and such a folder existed). Here is the code in case I wasn't clear.
<html>

The jQuery library is definitely very useful for those who have development background experiences but don't have the time to learn Javascript in it's true nature. I've played with it on and off, on a few smaller sites I manage, and the outcome was truly amazing. I don't know Javascript at all, aside from the basics and I was able to create a very fun and fast UI very quickly for my visitors. I wonder though; Does the jQuery library hold up efficiency for larger sites?
I currently manage a site with over 1.6 million post, averaging around 15,000 post per day this month. With me not having the time to really learn Javascript and I don't have much of a budget to hire someone to do the work I want yet, it would seem logical to use jQuery if I already know how to use it, right? I just worry, with the growth rate for the site at it's all time high, I'm afraid that jQuery will do more bad then good.
Are there any high traffic sites successfully using jQuery that you know about? has anyone experimented with jQuery on their high traffic sites? Would it seems more sensible to hire someone to do the Javascript work?
