Making My Script Smoother?
Jun 11, 2010
I recently made my first ever ajax chat, and works given im a noob im quite happy about it :P How ever, sadly - its not smooth like some ajax chat's i've seen out there. And when i submit a message to teh chat the page refreshes.I was wondering if some one could help me by explaining how i can improve the efficientcy of it so it won't refresh and reacts alot quicker to create a live effect - This is what i got for my code:
<script type="text/JavaScript">
function sendMessage()
{[code]....
The PHP is chat.php loads the chat (a MYSQL query getting latest 20 chat messages and loops them out into the div)chatpost inserts the message to the table.

I'm having a great deal of trouble figuring out how to make this div continuously scroll smoothly while hovered over the arrows. It's almost like there is easing on the animation but I don't have any easing set for this instance of the animation. I'm really at a loss as to how to make this smoother.

What is the trick to get this to work?

I'm working on a website for a client and we've decided to use CSS3 instead of Flash for multiple reasons, compatibility with mobile devices being the main. However, there's a lot of animation on the page such as fading, positioning and opening/closing and it seems to be tripping over itself attempting to process everything.
I've created an animation class that schedules all of the animations so that there's only one setTimeout running for those animations at any given time. I've also set it up so that any web browser capable of CSS3 transitions use those instead of the JS animations. The animations lag in both CSS3 and JS functionality, although the CSS3 is slightly better.Some animations lag even if they're the only animation running. For instance, trying to fade a full-screen image in/out chugs even on test pages I've created only containing the one function.
I understand that Flash uses hardware acceleration and has optimized rendering, and the reason the browser is lagging is most likely because it's all being processed unoptimized and through the CPU. However, I'm sure there must be a way to make this site smoother than it is.I'm posting here because my deadline is coming hard and fast, to ask for assistance with:Tips on how to optimize my code to run smoother in JS and/or CSS3.how to be able to fade large images/areas with less lag.I've been trying to move most of my code into OOP as I've gone along, but some functions are still a bit "spaghetti" due to my time crunch.

I have a page created.
Links are listed on a column on the left that jumps to content on a large right hand side content column.
I used a fixed div on the left nav to always show these links when navigating and smoother scroll js to make the transitions animated in a scroll.
The problem is this needs to work in IE6 and css position fixes don't render in ie6.
CSS hacks to make this fixed break the smooth scroll and what I have found with JQuery floating menus don't work with it either.

I have a client who wants a gallery of images to pop up on her enter page similar to this site, http://bit.ly/mUscmo . It won't be identical, but she likes the way the images all pop up and then just stay there.I know how to function JavaScript, but I don't know how to write it from scratch. Is there any where I could find a code that does something similar to this?

There are a lot of extremely smart members here, so I thought if the knowledge is out there, this would be the place to tap into it. I have included the code below that I am working with. What I want is for a person to enter their name and room number and coffee preference. Then a cookie will store that information and tell them a cup will be sent to them at their room. When the page is loaded again their preference will be remembered and they will be offered a discount for their favorite coffee. This is part of a self taught book I am studying.
Most of it works, but I think the selection of coffee from the radio button is not being stored in the cookie, or at least I can not recall it. I was also wondering if there was some way that I could combine the makeCookie and welcome functions so that there would only be one button to click on the page. Code:

I am not sure this belongs in the JavaScript section so apologies if it doesn't.
I want to be able to open a link in a new window, but make sure the users are not able to modify the URL.
Is that possible?

I am trying to write a regex that will parse BBcode into HTML using
JavaScript. Everything was going smoothly using the string class
replace() operator with regex's until I got to the list tag.
Implementing the list tag itself was fairly easy. What was not was
trying to handle the list items. For some reason, in BBcode, they
didn't bother defining an end tag for a list item. I guess that they
designed it with bad old HTML 3.2 in mind where you could make a list
by using:
<ul>
<li>item 1
<li>item2
</ul>
However, I need to make this XHTML compliant, so I needed to add the
</li> tag into the mix. Unfortunately, the only way to find where to
put it is to find the next[*] (<li>) tag or an open list (in the case
of nested lists) or close list tag. I was trying to get a rule that
handles the list items to work, but it only matches the first item in
any list. Here is the line of code:
bbcode =
bbcode.replace(/[list(=1|=a|)](.*?)[*](.*?)([*]|[list]|[/list])/g,
'[list$1]$2<li>$3</li>$4');
First, I check to make sure that the list item is inside a list. Then,
I match the[*] tag to find the start of the item, then I match either
the next[*],, orto determine the end of the item.
This successfully prevents a list item outside of a list from being
made into a <li> element, but only matches the first list item in a
list. Is there any way to make this match all occurances of this
pattern without looping over the statement until the pattern can no
longer be found?

I have a graphic with a rollover for site navigation on each page. I
put the page to go back to in the rollover javascript.
My question is, is it possible to put in some code that will refer the
visitor back to whatever page they came from rather than one I
specify?
The rollover is combined with a tooltip script to make matters fun
(below). However, I'm quite happy to lose the tooltip to have the link
perform as a back button.
<a href="../index.asp"
onmouseover="document.images['link1'].src=img2.src;
showtip(this,event,'Back to home page');"
onmouseout="document.images['link1'].src=img1.src; hidetip()";><img
src="bhome.gif" name="link1" border=0></a>

I don't know if this will work, but I'm trying to put a google map on my website and in IE, the div containing the map needs to have a width value in pixels in order for the API to center the map properly. want a div with 100% width, which is inside another expanding column. This works everywhere but IE. My question is, Is there a way, using jQuery, to get the div to discover its inherent width and then apply that in pixels, as an inline style, to that tag? It would also have to redefine its width when the window resizes.

I am trying to get a dialog box to open another dialog box. Clicking on "more search options" the first time results in opening a dialog box. Clicking "search" within the dialog box results in opening up a second dialog box. But this only works the first time I click on "more search options". In other words, the second dialog box only opens up only once. To get the second dialog to open again, I have to reload the page in the browser. CSS and jquery code can be downloaded from [URL].

I'll get it out their early, I am somewhat of a javascript novice.
Here is the code I am working with:
<script type="application/javascript">
$(document).ready(function() {
var numitems = $("#foo6 > li").length;
var secondstartpoint = numitems -3;
[Code]....
As you can probably see I am trying to set the start point of a jquery carousel to equal a variable that I have created. You can see I have tried " start: secondstartpoint", but this isn't working. I think possibly because the way the plugin is formatted so that the "start" option can only equal a number.
