JavaScript - Glowing/pulsating Effect
good day!
i just want to ask how to make a glowing effect using javascript, i'm kinda new to this stuffs 'coz i'm not really a javascript coder, i now only know the basics. i already did it on a text and it's working but when i tried to apply it to the one i'm doing right now it's not working. it's with HTML5 Canvas. here's the part of my codes where i'm trying to do the glowing effect, hope i could get some help here. thanks! var c=Math.max(0,parseInt( -50+284*(z/PYRAMID_TOP))); var gradient = ctx.createRadialGradient(90, 63, 100, 90, 63, 50); gradient.addColorStop(0, "rgba(255,255,0, "+1+")"); gradient.addColorStop(1, "rgba(255,255,255,"+0+")"); ctx.fillStyle= gradient; Similar TutorialsHey! I have a problem and i have looked all around for an anwser. I need some type of code or script to make my 3 images glow with opacity going in and out. Basically, I have 3 images on a page and I want one of the images to randomly fade in for a couple secs then fade out then repeat somewhere between 4 to 20 secs. But, all the images have the same concept going on with their own random fading in and out (without mouse over). Does anyone know of a script or anything that could do this or if anyone could help me make something like this? Not very good with JS. Thank you for taking the time. Have a good day or night I am using ASP.NET and AJAX here. basically what I want is a nice little slide effect to show the next batch of images in a mini slide show. Example: << prev [image1] [image2] [image3] [image4] Next >> << prev [image5] [image6] [image7] [image8] Next >> so when the user presses next or previous, it will SLIDE to the left/right. the databinding is done at the server side end and in an update panel so it does an async postback when they press next/prev. how can I go about doing this type of effect? I need to have an image hyperlinked to a js function that fades text elswhere on the page. I imagine it looks something like <a href="(some js function or somethingrather"><img src="theimg.png"></a>, but how do I do it exactly? I would like code that I can just copy and paste in my header that is set to fade a specific line of text, and be able to hyperlink and image to initiate the js. Please help. Carson www.carsonkahn.com Hi, Does anyone knows how to use this effect using javascript? http://www.modonline.com/ Really appreciate if someone can help me. Thank You, Nadun I really like the lightbox2 effect (http://www.huddletogether.com/projec...tbox2/#example) but I need help doing what I'm trying to do, for some reason I cannot get it to work, maybe you have a better recommendation? I have one large image, its a tear out of a magazine, I want the initial image to be the entire page, but I want the user to be able to click on the text area of the page and have that enlarge so the viewer can read it clearly. Any ideas? Thank you, Dustin Quick question, I need to get the hover effect that Templatemonster has, for example click here and hover over a template image see how you get that larger pop-up image that disappears instantly after you remove you mouse from the template thumbnail image. How would I get that effect? Thanks!!! Hey guys, I'm new to the forum and thought I should sign up to learn a little more. I am trying to work on a lightbox for my personal portfolio site which opens up numerous images in one lightbox that you can scroll through. However, I want thumbnails below the main image too. The following link shows exactly what I mean, just click on one of the images... http://www.weareunit.com/index.php?p=3D Thanks Hi friends, Im new with JS. How to make the roll over effect in JS. An image, on roll over, the big size of the same image needs to appear. regards anoop I want to add the the faded effect to the slide pics that I make them change by timer and I don't know how to add the faded effect and make it work on IE and Firefox.
I've been doing some research on javascript's impact on the time it takes for a page to load, as defined by firebug's "Net" tab's "onload" demarcation (the red line). It seems that aside from dynamic data that's not part of the HTML, enabling javascript always slows down the page. I've checked wikipedia, yahoo, digg, even google; a javascript-enabled loading of each site shows a later onload() event compared to loading the same site without javascript enabled. My question: Can anyone think of a site that loads faster with javascript than it does without javascript? Help, I have a navigation menu that has a flyin effect for each item using Javascript. Right now, The Javascript flys in a picture (in the same location) no matter what item you hover over. How can I get it to fly into a different position for each item.

Thank you! I found a very intressting JS function at this webpage: http://www.dynamicdrive.com/dynamici...edcollapse.htm I wonder if someone knows wihich part from the JS-file i should change/delete so i only get the fade at exempel 1 and not the slide/rolling effect. I only want the fade. The JS is: Code: //** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 24th, 08'- Script rewritten and updated to 2.0.
//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).
//** March 5th, 09'- Version 2.2, which adds the following:
//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads
//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly
//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
//** July 3rd, 09'- Version 2.4, which adds the following:
//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state

Hi guys, I have this piece of code at the moment and I would like to add the easing effect, would anybody please show me how to incorparate this into the code I currently have? Code: $(function($) {
$.localScroll.defaults.axis = 'y';
$.localScroll({
duration: 1000,
});
Im using the jquery.easing.1.3 plugin. I have read somewere that the easing effect needs the .animate function, for example .animate ('easeInOutExpo'), I was kind of hoping just effect: 'easeInOutExpo', would be ok but like i say im sure it needs the .animate function with this. Any help would be hugely appreciated. Kind regards, paffley Quote: http://codecanyon.net/item/html-befo...preview/153778 http://codecanyon.net/item/beforeaft...preview/529151 http://www.catchmyfame.com/2009/06/2...eafter-plugin/ I need this effect, I will explain below The first, we have if we slide on the left. when we slide on the right if we slide to END the result will be: OR It's use jquery plugin, I want to find the same things with only javascript, not use jquery. Because, I'm use it on ipod, iphone, android. It's not allow jquery. I'm really need it. please, help me. Thanks for your time Im looking at how or what this effect is called i am not even sure if it is javascript i assume it is from looking at the code. But i cant seem to convert it to what i want. So if someone could point me to a more simple version of this code or what the technique is called that would be great. Here is the page. http://www.pizzacapers.com.au/the-me...nature-pizzas/ What i am talking about: You click the pizza and it comes up inside of the border picture on the left side of the page. Thanks i just read the other thread and i want the reverse affect. the slideshow opens in a new window and thats not what we want because the link is to a persons profile page. we dont want two versions of the site open at once. this is the slideshow that client did on his own then i got the project. http://www.dynamicdrive.com/dynamici...nslideshow.htm Code: imagearray: [ ["pool.jpg"], ["http://mysite.com/cave.jpg", "http://cnn.com"], ["fruits.jpg", "http://cnn.com", "_new"], ["dog.jpg", "", "", "This image has a description but no hyperlink"] //<--no trailing comma after very last image element! ], i see "_new"], in there but i dont know if there is a command for self is it _self .. im not sure.. i assume it is different than the html target code. so how do i make it open in the same window just like target = self sorry had to change the target to non coded format to show up right in this thread Hey I'm trying to make a slot machine effect in JS - i had an ajax example but was far too complicated to manipulate to communicate with my server so im working from ground up. The way ive done it is simple html and a submit button. But i want the submit button to first create a "rolling through the images" affect like a slot machine does - then stop left to right in that order (basically like a slot machine does). Now this is beyond what i know in JS but i then also want it to know the result of the images store them into an array and push it to my PHP so i can process it on my server. Is this even possible ? And has any one ever tried such a thing because im stuck but really wish to make this for my gaming website. Hope you can help! Hi, I have problem with javascript for image effects... Here is the LINK... login with theese nick and pass: nick: google pass: googleads the problem: When you log into, on the top of the page are 4 images with fade effect... But effect is wrong. When I came first I see those images in full collors. How to change my script to show them in grey when I first came? Thanks in advance... Can some one help me step me through this last part of my script i have made. I have completed my entire chat program but currently i use: <meta http-equiv="refresh" content="5; URL=shout.php"> This is what keeps my chat room up to date, but this is pretty ugly due to the fact the browser makes a refresh. So i was hopeing some one could step my through to add ajax that makes a live affect with it appear to refresh. The script that has this chat is in the structure of: Code: <meta http-equiv="refresh" content="5; URL=shout.php">
<?php
function get_chats(){
//query
//while loop the logs out
}
getlogs();
?>
And thats it. I took a look on W3 about ajax and most of it was involve an event occuring such as submit/on key press which isn't what i want as some times a user may not do anything but i still want the chat to keep "up to date". I found one tutorial but it was over complicated to just take snippets out to put on my chat without knowing what it did or what to change for my chat to make it to work. Hope you can help - im a quick learner when i see the right example of what i need. Greetings everyone; Jesse here. Long time reader, first time poster. I have a personal website, currently in development, located at: http://www.jesselang.ca If you click the right-facing arrows along the right side you'll open a side-bar column, clicking a left-facing arrow will then close the side-bar. This functionality is "OK" at best. What I would like to see is clicking the right-facing arrow causes the current sidebar to fade-in, and simultaneously have the arrow flip to a left-facing icon; the idea being to add a toggle function to the arrows. The code I'm using at the moment is shown below, this string works for me because it only allows 1 sidebar container to be displayed at a time... which is ideal. Code: <script type="text/javascript">
lastone='empty';
function showIt(lyr)
{if (lastone!='empty') lastone.style.display='none';
lastone=document.getElementById(lyr);
lastone.style.display='block';}
</script>
The respective html looks something like this: Code: <a onclick="javascript:showIt('interestcontainer')" class="arrow"><span>show interests sidebar</span></a>
The coresponding html for the container to display looks like this. This code also shows the "hide container" button: Code: <div id="interestcontainer" style='display:none;'>
<h4>interests<a onclick="interestcontainer.style.display='none';" class="back"><span>back</span></a></h4>
And the CSS looks like this: Code: a.arrow{
display:block;
float:right;
background:url(../images/ico-arrow.gif) top no-repeat;
text-decoration:none;
overflow:hidden;
width:13px;
height:11px;
margin-left:3px;}
------------------ Would it be asking to much to have someone help me achieve the following functionality? -load page with all side containers hidden -display only 1 side container at a time -fadein and fadeout effects -same button displays and hides -button swaps images for displat/hide commands Again, my code can be seen at: http://www.jesselang.ca http://jesselang.ca/files/style.css I'd very much appreciate the help. Thank you in advance. *j |
