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.

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.

I have scoured the net and found nearly what I'm looking for, but not exactly, and I don't really know javascript, so trying to piece together bits of code hasn't worked. What I need is the script for a live clock with date and time format exactly as follows: Sunday, 07 June 2009, 24:00:00 (GMT+1).I have two separate files with the following code, which gets me close to what I need: Sun Jun 07 19:05:48 2009 Obviously the time is in the wrong place and it doesn't show GMT+1. These are the scripts:
Code:
function update() {
time = Date();[code]....

Currently my site uses dual session checking one in the server side (about 30 minutes) and the other on the client side (10 minutes). Once the timer ends and the page hasn't been refreshed the client side checking will end the current session. This is good if the user is just viewing but the problem occurs if the current page has forms that could take more than 10 minutes. My forms and fields are all dynamic and my javascript for this session checking is found on one template found on all pages. Is there a way to do this: detect if the user is typing? if yes do/stop the timer else reset the timer and start detecting again

Is there something that will update as soon as the user changes information in a textbox as appose to what onChange does, which is update once the focus has been taken off of the textbox? I am writing a custom cart and I am using AJAX to update the price according to how many they are ordering, I was hoping to have it update the price as soon as the user put in the volume, but it doesnt update until the user clicks somewhere else on the page.

I've already developed a system for doing this which isn't perfect i'm wondering if there is a better solution. Here is the code I got atm.

I don't like the use of key == 8 and length == 1 to detect that chatmsg box is empty, but the event triggers before the val() of the chatmsg actually changes. So is there nothing better I can do?

I'm working on a form to add items within a bespoke CMS and have been contemplated the pros and cons of implementing a type of live search within the form. The way I was thinking of it working is:Users start to fill in form to add items to the databaseI don't want them to duplicate these items so thought that as they type the item name, I could return a table of similar results below with a note to say "The database already contains these similar items - Please check to ensure you are not replicating ... blah blah"My 2 questions are a) is this actually of any benefit to the user or should I just tell them to check the list of existing items before starting and b) anyone know of any tutorials to tell me how to do it!

This is a calculator that calculates how much a user can earn from their referrals depending on the user's Level & Member type. It's supposed to be updating live (onChange) when the user types in new values in the fields, but nothing is happening. [URL].
Code:
<html>
<head>
<script type="text/javascript">
function calculate(){
// eval makes the script know the value is a number, and not text
var myLevel = eval(document.earningsform.level.value);
var memberType = eval(document.earningsform.type.value);
var viewed = eval(document.earningsform.viewed.value); .....

I want to make a switch statement that will display something different depending on the time of day. Once I saw something like getTime (?), but it relied on the user's clock. I know that you would expect me to at least research getTime so that I'm asking about something more specific, but I don't think it's what I need because I want mine to give the same result regardless of the viewer's time zone or how off thier clock is.

I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen()
{
var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..

Can javascript do something at submit() time to distract the user?... like clear the form... or clear the screen ??
I have seen some fancy ways to prevent multiple clicks..... but a number of my cgi's eat up several seconds before they can respond and I would like to keep my user out of trouble.
Whatever it is. it has to be non-modal and not involve nph headers (my webserver does not support them).

I need to remember the time when user closes the window and later when he/she comes back, site will highlight latest news that happened when user was offline. So far the best solution I have found is jquery.unload (since I use jquery): it sends some data to php script (which remembers the time) via ajax when unload event triggers, so is it the best way to solve this problem?

I was wondering if it is true that the Date object gets its date from the user's local time, if so, could the user "hack" the time by adjusting his local time?

I'm trying to figure out with Java Script how I would have Java Script check and see if a check box is or not empty. The goal is to only allow the user to have one box checked at any time in a form. That means, if they click on another one and there is already one checked, it would uncheck the one that was checked and make the one that the person checked on next checked.
