JavaScript - Timed Images

First off, i have no idea what to do, because when i get beyond the realm of html/css, vb and php (some) i become lost. I hope someone can help me achieve this because i have no idea what i'm doing, and I've been at it for 2 weeks and no money to hire someone to do this for me. If you ever been in my situation, you know exactly how i feel. I have no code of my own to show you, but hope someone can still help me.

I'm have a number 0.0000000, and every min i need that number to increase to 0.0000000, than to 0.0000002 and so on and so forth. Every time i click a button, whatever the number has risen to, it will reset it back down to 0.0000000.

Can someone help me out with this?

Hello,

I am trying to create an image carousel for the website found here. As you can see everything works fine, however, I would like it to automatically scroll through the images every X seconds. I did not write this script (the credits are still in tact) and I know very very little about writing javascript, so I am hoping someone here can help. Thank you in advance for any replies and any suggestions/tips to making it a better script.

The HTML where inserted onto the page
Code:

<script type="text/javascript" charset="utf-8">var my_glider = new Glider('my-glider', {duration:0.5});</script>

Looks to me like this ought to work, but since I'm here obviously it doesn't. Regarding the HTML in question, there are divs and they do contain child elements. I'm trying to write this in as generic a fashion as possible, without using IDs or other means of targeting elements. And yes, the jQuery library is referenced/linked to the page. Any pointers much appreciated. Thank you


<script type="text/javascript">

Hi, im fairly new at all this, so please forgive me if I have misunderstood the guidelines on posting threads for this topic.

Im needing some help with adding a timed delay for a widget I have on my website.

My website is hosted on moonfruit, a flash based web builder, its very beginners level, and so this makes me feel like the new kid at school posting on this forum.

however moonfruit does have a HTML/JavaScript snippet

Which allows me to paste in code and show the cooliris gallery

But is has become crucial to my websites completion that this widget must have a timed delay on it

ive been at google for days till the point where im seeing the same pages again, and have come across setTimeout, unfortunately that's as far as I can seem to go, ive tried pasting in the code in numerous places and I just cant get it to work, i have pasted in other JavaScript codes, and they have worked, so i am convinced that its just me being a noob, other than it being a limitation on moonfruit

I would appreciate any help with this

Here is the code that im trying to get a delayed time of 10 seconds or so.

[CODE]
<object id="o" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="845" height="350"><param name="movie" value="http://apps.cooliris.com/embed/cooliris.swf"/><param name="allowFullScreen" value="true" /><param name="allowScriptAccess" value="always"/><param name="flashvars" value="style=dark&backgroundColor=#0d0d0d&feed=api://www.flickr.com/?user=41683862@N04%26album=72157622009594203&glowColor=#FFFFFF&showSearch=false&showEmbed=false&show Tutorial=true&showChrome=true"/><embed type="application/x-shockwave-flash" src="http://apps.cooliris.com/embed/cooliris.swf" flashvars="style=dark&backgroundColor=#0d0d0d&feed=api://www.flickr.com/?user=41683862@N04%26album=72157622009594203&glowColor=#FFFFFF&showSearch=false&showEmbed=false&show Tutorial=true&showChrome=true" width="845" height="350" allowFullScreen="true" allowScriptAccess="always"></embed></object>
[CODE]

Again any help is most appreciated

Hi,

I've ben trying to figure this one out for days now and so I'd thought to give it a shoot here to see whether anybody can give me any advice or inspiration.

Basically what I am trying to do is command a click of a bottom for a certain set time.

for example:

On the google main search engine page. Once ive typed in a search for "skateboards". I would then like to command the "search" bottom to clicked at 10 pm at night thus executing the search for "skateboards" going into the next page with all the search results.

I was wondering if it would be possible to right a Java command that could be run in the Mozilla Fire Fox Scratch pad tool. ( Which is found under Tools --> Web Developer.)

Please let me know of anything. It would be very grateful.

Thanks,

Can someone tell me why this short script won't work?

<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
var number = rand(7);

}

</script>

</head>

<body onload="JavaScript:timedRefresh(10000);">

Knowing just enough about javascript to get myself in trouble, I have put three timed javascripts to appear from 18 December to the 1 January on three pages of my sister's website. The scripts are on the main index for the site; the index page for the bibliography folder /bibliography/ and in the education folder on just one page: /education/educationlinks.html.

Part one of the script inserts the css file; part two of the script inserts a "snowing" script and part three inserts a "make it stop snowing/let it snow" script. Everything is working perfectly for the main index page and the bibliography page. But I cannot figure out why the 3rd "make it stop snowing/let it snow" refuses to show up on the page in the education folder (the snowing javascript IS working on all three pages).

There are no errors being thrown and the education page validates.

This is the coding for the 3rd script:

Code:

// snowscript part 3:   Show the script between 19-31 Dec and 1 Jan 

var date = new Date();
var d  = date.getDate();
var m = date.getMonth() + 1;
dm = d + m;

if  (m = 12) 
{
   if (d > 18)
   { document.write('<script src="/scripts/snowlinkswitch.js" type="text/javascript" id="snow"></script>');   
   }
   else 
   { 
   document.write('');
   }
}
else if (dm == 1,1)
  {
  document.write('<script src="/scripts/snowlinkswitch.js" type="text/javascript"></script>');
  }
else
  {
  document.write('');
  }

This is the coding for snowlinkswitch.js

Code:

function myhref(){
    document.getElementById('myAnchor').innerHTML="please let it snow!";
    document.getElementById('myAnchor').href=location.href;
    document.getElementById('myAnchor').title="let it snow! let it snow!";  
    document.getElementById('myAnchor').onclick="location.reload(); startstop('spanstyle'); return false;";
}

// 

document.write ('<div id="snowlinks"><img src="/images/snow3aa.gif" width="11" height="11" border="0" alt="*"> <a id="myAnchor" href="" onclick="myhref();hidesnow(); return false;" title="please make it stop snowing!">please make it stop snowing!<\/a> <img src="/images/snow3aa.gif" width="11" height="11" border="0" alt="*"></div> ');

I would search for a similar occurrence but have no clue about what search words to use. Does anyone here have an idea about what I have done incorrectly that is causing this to happen? Many thanks.

Hi Guys,

I'm embarking on a new project - although I've hit a wall.

I require a page to refresh at a scheduled date and time, several times a day.

For example, I would like the web page to reload the index at 3:15PM

So if anyone has the web page open during that time, it will automatically refresh for them.

Timing is quite important so I would need the script to use the server (hosts) time and not the end users time.

I am currently deciding on which server language to use, although Javascript is probably a suitable option? or would ajax be more the thing for this?

The webpage must execute the refresh at the time 3:15pm, so no matter when someone visits the page, even if its hours before, it must refresh at that time.

If anyone has any pointers on the best way to achieve this and what language to start with I am forever greatful

I do a lot of image design work and although I have worked with a few coders in the past but I haven't gone too much into coding myself, but its something I'm going to take time to learn and get involved in, so I'm not looking for script hand outs here, mainly just a nudge in the right direction.

Thank you guys!!

I want to be able to display the whole contents of a text file containing 4 paragraphs of text, on a static web page, as soon as a video finishes playing on the page. The video is to be set to autorun as soon as the page loads in the browser.

The text file mentioned above, is to remain hidden when the page initially loads and the video is playing. Please I need your advice about what JavaScript code to use to achieve this effect, and where to place the code in the HTML code of the web page. I am new to website design and the use of JavaScript code.

I have seen examples of code used for the timed delay of the display of an image file, after a video has finished playing. I do not know how to apply this to the display of a text file.

I do not want to convert the whole text file into an image file, as I feel this would negatively affect the search engine optimisation of the page, if there is no text content on the page. Thank you.

Hey everyone!

I'm in the process of creating a portfolio site for my artwork and I'm requesting help. The website has a scalable JQuery background which changes depending on which thumbnail you click.

I've uploaded the progress he
http://www.aldousmassie.com/newprogress

I'm using this code at the moment to scroll through the background:

Code:

<!-- SCRIPT FOR CHANGING BG ON CLICK -->

<script type="text/javascript">
					imgs=Array("img/00.jpg","img/01.jpg","img/02.jpg","img/03.jpg");
var x=0;

function change() {
					document.getElementById("bgimg").src=imgs[++x];

if (x==3) {
x=-1;
}
}

if (!imgs[x+1]) {
x=-1;
}
</script>
					
<!-- SCRIPT BELOW OVERWRITES SCRIPT ABOVE -->

<script type="text/javascript">
					imgs=Array("img/08.jpg","img/09.jpg","img/10.jpg","img/11.jpg","img/12.jpg","img/13.jpg");

var x=0;

function change() {
					document.getElementById("bgimg").src=imgs[++x];

if (x==5) {
x=-1;
}

}

if (!imgs[x+1]) {
x=-1;
}
</script>

Unfortunately, the bottom code overwrites the top. Is it possible for each different background image to have their own "set" of images that could be scrolled through onclick?

I'd appreciate any tips that point me in the right direction. Thank you.

Hi there,

I've been searching for an answer to this for the last few days but with no luck, so I thought I'd register here to see if anyone can possibly help.

All I've been able to find everywhere for this is examples of changing images when rolling over them or clicking them, and I don't need that.

What I need is a bit of javascript that will recognise some image paths on a page and replace those image paths with other ones.

It's for an ecommerce website on a certain platform, using a customer reviews section which outputs star images based on the customer's rating. So, the images used (which look awful) are, for example, "sourcehere/stars_5.gif", "sourcehere//stars_4.gif", and so on. Just 5 of them.

I want to design my own 5 images, upload those images, and then have the javascript replace the rubbish looking ones on the page with my own images.

I thought I'd be able to find something quite easily, but so far all I can find is examples of mouseover events and so on, and I don't need any of that, just the entire image replaced with my own image.

Can anyone help please? I'm a beginner with javascript so I'll need it spelled out to me! Thankyou for your time.

Please help have a look at the scripts...
Where's gone wrong that whenever an image fades out into 0, it reappears before another image comes out?
I've wanted to make the image disappear shortly before a new image is loaded.
I've worked on this and played around with the scripts, yet no finding...
Please do tell me if you know the answer to it. Thanks.

</html>

if the elements have name attributes with the same value, according to legacy DOM, it will return an array of those elements if you access the name property of 'document'.

However, this doesn't apply to img elements. If the HTML code is as follows:
Code:

<img src="img/a.jpg" name="pic" /><img src="img/b.jpg" name="pic" />
<form name="pic">a</form>
<form name="pic">b</form>

then
document.forms["pic"] (return an array) <-- as expected
document["pic"] or document.pic (return an array) <-- as expected
document.images["pic"] :
in IE -- it returns the last image
in FF -- it returns the first image
~~OMG~~

any idea?

thx in advance.

Good afternoon I am trying to make a form and keep getting stuck on one thing, don't know if JavaScript is the way to go so any advise would be helpful.
basicly i have a form
giftcert.html -that has text input boxes the user fills in and a link to the next page for the user to pick a gift card
giftcards.asp -the user picks a gift card by radio buttons (over 100)grouped by name and then pushes a button to take them to the next page passing the value of the radio and image (here is the issue)
giftcert.asp -this page displays the text boxes from the first page with the value already present (used asp to achieve) and the value of the radio button (a stock number - used asp to achieve) and i want a sample of the image attached to the stock number.
how do i pass the image attached to the radio button from giftcards.asp to giftcert.asp
i don't know where i am going wrong
a) how do i attach the image to the button do i use an onclick="pass src" and how
b) how do i get the image to show up in giftcert.asp

Code:

<body>
<center>
<script type="text/javascript">

var imageSrc = ['<img www.mysite.com/subfolder/001.jpg></img>','002.jpg','003.jpg',
'004.jpg','005.jpg','006.jpg'];
var imageSrc2 = [];;

function copyRandom(){
if (0 == imageSrc2.length) {
imageSrc2 = imageSrc.concat();
}
var randNum = (Math.random()*imageSrc2.length) | 0;
return imageSrc2.splice(randNum, 1);
}
</script>

<!-- <button
onclick="document.getElementById('xx').innerHTML = (copyRandom());"> -->
<button
onclick="document.getElementById('xx').innerHTML = (copyRandom());">
Draw A Card
</button>
<div id="xx"></div>
<!-- <div id="xx"></div> -->

</center>
</body>

Why are my images broken in this script? Specifically "<img www.mysite.com/subfolder/001.jpg></img>" as the rest are just placeholders until I solve the first one.
