Detect/add Character In Input Field?

Jul 2, 2007

I'm not a JS expert, but is there any way to detect if there is a certain character at the ending of a sentence in a text input field?

for example, when a user puts "Hello, my name is Gary" into a certain text input with a specific ID and using the JS OnChange event, the script will add a period ( . ) if it is not detected.

or, when a period is detected at the end of the sentence ("Hello, my name is Gary."), it won't do anything.

I got this idea from reading the W3 School onchange doc, but I'm not sure if it's possible.

If I type characters using a Chinese text input (one where I type 2-3 latin characters for each Chinese symbol) there is no onkeypress or onkeydown event triggered. Any idea how to detect those characters please? I need to catch those chars in JS to pass them to a plug-in.

JQuery :: Limiting Character Input - Also Displaying Input Fields Contents

Sep 7, 2009

I have a pretty basic set of things I want to do: Capture key press, compare against an allowed list, block keys that are not in that list, replace a space by a dash if entered. As this is happening, I have a span I wanted to be updated with the live values. The username field at [URL] is exactly what I am trying to do, though I have trouble dissecting how they did it. Here is my attempt, which is off by one keypress for some reason.

How To Detect That User Closes The User-agent Window ?

Dec 2, 2005

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.

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?

Live OnChange - Run The Script Every Time A Character Changes Even If The User Is Still Typing?

Aug 19, 2010

I have a registration page with a username field and every time a character is type I would like to call a javascript function to test for a unique username. My function is working fine but I'm currently using onChange to call it and I noticed that onChange is less of an actual onChange and more of a onChange if onBlur. Is it possible to run the script every time a character changes even if the user is still typing? Note, I'm using ASP.NET in VB to write this page but I'd like to do this with javascript and not post back if at all possible.

Input Character Set Handling

Nov 10, 2006

I am struggling to find definitive information on how IE 5.5, 6 and 7
handle character input (I am happy with the display of text).

I have two main questions:

1. Does IE automaticall convert text input in HTML forms from the
native character set (e.g. SJIS, 8859-1 etc) to UTF-8 prior to sending
the input back to the server?

2. Does IE Javascript do the same? So if I write a Javascript function
that compares a UTF-8 string to a string that a user has inputted into
a text box, will IE convert the user's string into UTF-8 before doing
the comparison?

I think that the answer to question 1 is probably "YES", but I cannot
find any information on question 2!

Can't Change A Var To Accept More Than One Character Input?

Sep 26, 2010

I'm trying to implement a OSC addon to update the options price in realtime fromww.oscommerce.com/community/contributions,1385, but it seems to only work with single characters currency symbols, like $, €, £, etc. any symbol that as more than one character, like Brazil Real R$, or C€, or Svenska Kronor Skr, doesn't work and the price doesn't update, it stays R$ 0.00 whatever options you choose.I need to use this contribution with the Brazil Real symbol at the left of price like R$ 999.00.Also I can't make it work like 10.000,00. It only works like 10,000.00. But this point is not so important.I have tried everything for some days, but I don't know javascript.Here is the code:

Code:
<script language="javascript">
<!--

Detect If User Has Authenticated

Oct 26, 2006

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.

Detect When A User Leaves Site?

Aug 3, 2009

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?
