Ajax :: Website Login Implemented As Overlay DIV
Feb 9, 2011
I have a login panel on my website that is implemented as an overlay div. So if the user clicks on a link that requires authorization, this div is made visible with javascript. In the login panel there is a form consisting of a field for the user name, the password and a submit button. What I want to do is when the user entered his name/password and clicked on submit I want to do an asynchronous request and check whether the password was correct.
My question now is: What is the best way to do this check? Intuitively I would create a response xml file where I store a variable like <correctPassword>1</correctPassword> and check whether this variable is 1 (true) or 0 (false) and react accordingly.
Is that the way to go or is there a better approach to achieve this?

I am trying to do implementation of the Nivo Slideshow on my website. I've been at it for a couple of days now and I'm just about ready to give up:
Here's my markup:
<div id="slider">
<img src="/images/Slide1.png" alt="" title="Dead Kool"/>
<a href="[URL]"><img src="/images/Slide2.png" alt="" title="Alex Kidd" /></a>
<img src="/images/Slide3.png" alt="" title="Asteroids" />
</div>
My CSS:
#slider {
position:relative;
width:620px;
height:350px;
background-image:url(../images/title.gif);
background-position:-10px 30px;
background-repeat:no-repeat;
background-attachment:fixed;
} .....
Slider CSS:
/*
* jQuery Nivo Slider v2.3
* [URL]
*
* Copyright 2010, Gilbert Pellegrom
* Free to use and abuse under the MIT license.
* [URL]
*
* March 2010
*/ .....
The test site is here [URL]. For some reason I just can't get it to work.

I would like to add a feature to one of my sites which takes a URL and displays the webpage with certain information overlayed on top of it. I figure I can retrieve the webpage and display its HTML in an iframe (local) with an added BASE HREF tag so that the page displays correctly, while its contents are accessible through JavaScript since it's on my domain.
Here's where I was wondering if anyone could give me a pointer before I start searching for hours... how do I get a list of all links inside this iframe and their positions so I can create new elements and place them there (like a small info icon next to each link to click to show the overlayed info). Links could be text or images. I'm not really sure how I'd find the locations then place new elements at those locations.

I wanted to ask how it is possible to get error messages from the server till it is implemented in the remote method.What do you think is the less work intensive alternative.I also wanted to ask if i have two fields A and B, and the values of B depends on A. How do i make it with the plugin and the remote method ?I saw that there is a way of writing custom methods:URL...But how do i combine it with the ajax calls?

Below I have a facebook login/logout script for my website. The login works fine. The AJAX requests the php file, waits for the "Success" response, and then reloads the page. The logout doesn't. Instead the browser goes to the PHP file with just the word "Success" printed on it. I've separated the xml request as a separate function but that doesn't appear to solve it either. code...

I'm developing a jquery web application. On start the user gets a login screen to sign in (verification and session checking is done by php). After login the user gets the application screen where most of the server communication is done by ajax (json). If there was no ajax communication for a long time (timeout), the server (php) sends a session timout (something like error=timeout) and wants the user to sign in again. Now comes the tricky part:I want to show a window where the user enters the login information. Now the application should send these information to the login.php and after acknowledgment, the last ajax request should be sent again.Is there a possibility to send an ajax request again with same settings?

In Chrome, the login page on my schools educational online platform doesn't remember the login info. So i made a bookmark with this javascript injection, that fills in the info, and focusses on the 'aanmelden' button (='login' in dutch), so that i only have to press enter to continue. Here's the javascript injection:javascript: ocument.getElementById('username').value='23889493984';document.getElementById('password').value='4 42384985';return false;document.getElementById('login').focus();This works fine but i'd like to make it happen faster. I wish i could let the script be activated instantly when the page loads, so i only have to press enter, or if possible, let the script click the login button itself.

I want two buttons: one for login and another for logout. Initially login button is enabled and logout button is disabled. When I click on login button, the logout button should get enabled and the login button should get disabled. And after that, when i click on logout, the login button should get enabled and the logout button should get disable.
Here's how far I could go with it,but it doesn't work.

I have a a html page that is used as a login page.I know it is not secure but this is just for learning purposes, I'm not using it for anything important.My problem is that when I put in the correct login all that happens is the page just clears the text boxes as if you were starting over.I am trying to get it to go to register.html which is located in the same directory as the login page.

I am able to run perfectly the following
<li><a href="javascript:ajaxpage('login.php', 'ajax');">Login</a></li>
But not the following
echo "Welcome Guest!<br><a href=javascript:ajaxpage('login.php', 'ajax');>"
I removed the " around the javascript:ajaxpage('login.php'); as it was giving me syntax error. But I am unable to cal login .php upon clicking Login. I tried various combination of single quote and double quote but I think I am missing some fundamental rules of single and double quote combination....or may be something else.

I'm a AJAX newbie, I was wondering if I can use the .responseText method, to load the text from other website? For example, how can I download the data from "[URL]" and display the data in my own way? It seems that the .responseText/.responseXML does not work here...

I just started implementing jQuery in the College site that I work on. I really like it, but on the pages I have used it on, I seem to get a 3-4 second lag sometimes. The puzzling thing is the "sometimes" part since this only happens about 25% of the time.
The first place I am running into this is on the homepage. I have implemented a content slider using jFlow. Sometimes when the page loads there is a 3-4 second lag when you can see all of the slides. I submitted this problem to the tutorial page where I learned how to make the content slider, but have received no response. All of the pictures in the content slider are pretty small, so I don't think that is causing the lag.
The second place where this problem happens is on a page where I have used a simple jQuery technique to stripe every other li in an unordered list. Again, about 25% of the time there is a 3-4 second lag before the striping effect kicks in. This is a very lighweight technique and there are no major graphics on the page so I don't know what is causing this.

Here is the code implemented on the search results page:
<div id="cse-search-results"></div>
<script type="text/javascript">
var googleSearchIframeName = "cse-search-results";
[code]...
The original code (from my Google custom search control panel) included a FrameWidth of 600 and I changed it to 500 but it didn't make a difference.

I have been working on this code in the last few hours with my boss and we are completely stumped. We are currently writing our companies new site, and we have come across a problem. We built a mini samples user control that shows on a few of our pages, that works with no problem. In that user control, we implemented a Rad Window Control by Telerik.
We have the auto populate thumbnail images and full size images from a database during the ItemDataBound event on our Repeater, this too works fine with no problem. When we first implemented the window, we added anchors to the thumbnails in the code behind so when a user clicks on a thumbnail from the parent page the thumbnail shows up in the window scroll bar at the bottom when the window opens. This worked fine except when you click on a thumbnail with the window closed the parent page would scroll half way down and then the window would open. The scroll function worked fine and had no problems with it, but we wanted to fix the parent page issue.
We decided to do accomplish the same task but with javascript. Since it only meant a few changes we thought it would be no problem, but we are stumped like never before. The javascript code we are using works fine, but when we try to implement it in the window, it doesn't do squat. We suspected that the javascript was being called before the page was loaded but even when using onload in the body tag it still doesn't do anything. We then added a literal and populated the text in the PreRender event but still no avail.
I made a test page that had the exact same javascript functions as the samples page but with hard coded content rather than data binded. This page works exactly as it should, but the samples page doesn't. I have already looked into the Telerik support forums but can't find anything near related to our issue so I thought I would stop by here as a last resort. I hope that we are just missing something and is an easy fix, rather than having to rewrite everything but if it's needed then it has to be done.
So here are my questions for you :Can you look at our code and see if we are missing something. Maybe a fresh pair of eyes will do the trick.Would going back to the anchor system be better and just try to fix the parent page scrolling issue?
I have posted our samples page and the test page that I made.

I have an inline datepicker on my page...I need two things:
1.) I've implemented the onSelect method, but what I really want to do is do a non-modal popup for the user to see what calendar events from the database that are on the date selected. I've worked out all the database and json parts, but now I need to make the popup near the calendar. I'm surprised that there isn't any mouse coordinates passed to the onSelect function. Anyone ever attempted something like this?
What I'm looking for is something similar to this: [url]
2.) Also from the link above, you see how they have a star on the dates that have events associated with that date? How can we modify the date so that there is some way to distinguish days that have events associated with them versus ones that don't.
