JavaScript - Display An Image For A Few Seconds
Hi people,
I'm building an online psychological experiment in which I need to display an image for 5 seconds on the screen. Does anyone has a simple script for that? I found some script that does image rotation but its not exactly what I am looking for. First, the rotation of the images doesn't stop and second I don't need something so elaborate. This is the script that I found. Code: <SCRIPT LANGUAGE="JavaScript">
<!--
var dimages=new Array();
var numImages=2;
for (i=0; i<numImages; i++)
{
dimages[i]=new Image();
dimages[i].src="images/image"+(i+1)+".jpg";
}
var curImage=-1;
function swapPicture()
{
if (document.images)
{
var nextImage=curImage+1;
if (nextImage>=numImages)
nextImage=0;
if (dimages[nextImage] && dimages[nextImage].complete)
{
var rel="nofollow" target=0;
if (document.images.myImage)
rel="nofollow" target=document.images.myImage;
if (document.all && document.getElementById("myImage"))
rel="nofollow" target=document.getElementById("myImage");
// make sure target is valid. It might not be valid
// if the page has not finished loading
if (target)
{
target.src=dimages[nextImage].src;
curImage=nextImage;
}
setTimeout("swapPicture()", 5000);
}
else
{
setTimeout("swapPicture()", 500);
}
}
}
setTimeout("swapPicture()", 5000);

</SCRIPT>
Thanks Similar TutorialsHi guys! I have a simple JavaScript stopwatch that displays the time using an html form with start/reset and clear buttons. Basically I'm making a speed calculator that converts seconds into MPH. All I need it to do is divide whatever the amount of seconds are by 40.91. So instead of it displaying the seconds being counted up (i.e. 2 seconds, would displayed as 20.455 MPH). Does that make sense? JavaScript is not my strong suit, and It's got me stumped. JavaScript: Code: var t=[0, 0, 0, 0, 0, 0, 0, 1];
function ss()
{
t[t[2]]=(new Date()).valueOf();
t[2]=1-t[2];
if (0==t[2])
{
clearInterval(t[4]);
t[3]+=t[1]-t[0];
t[4]=t[1]=t[0]=0;
disp();
}
else
{
t[4]=setInterval(disp, 43);
}
}
function r()
{
if (t[2]) ss();
t[4]=t[3]=t[2]=t[1]=t[0]=0;
disp();
t[7]=1;
}
function disp()
{
if (t[2]) t[1]=(new Date()).valueOf();
t[6].value=format(t[3]+t[1]-t[0]);
}
function format(ms)
{
var d=new Date(ms+t[5]).toString()
.replace(/.*([0-9][0-9]:[0-9][0-9]:[0-9][0-9]).*/, '$1');
var x=String(ms%1000);
while (x.length<3) x='0'+x;
d+='.'+x;
return d;
}
function load()
{
t[5]=new Date(1970, 1, 1, 0, 0, 0, 0).valueOf();
t[6]=document.getElementById('disp');
disp();
}
HTML form: Code: <input type='text' id='disp' maxlength=12 readonly /> <button type='button' onclick='ss()' id='butt' data-inline="true">Start/Stop</button> <button type='button' onclick='r()' id='butt2' data-inline="true">Reset</button> Any help is greatly appreciated!!! topic has been answered
hi everyone, firstly to call myself a noob would be inflating my ego. I have done one project in javascript so far and have had no schooling on the topic, however I have learned quite a lot in the last few months from this thing called the 'internet'. So far I managed to make an html image map that has various tooltips which will appear onmouseover, and the tooltip disappears onmouseout. Each point of coords that i have defined has a hyperlink to a different page on the internet. It works just like i wanted it to and i couldn't be happier, that is, when i'm using a mouse... When i am using a touchscreen device it is a different story. specifically i'm trying to port my html page to android as i figured it would be easy with the android sdk and webview (it was, but read on). What i found when i used the 'app' on my phone was that onmouseover works when you touch the screen, however it also registers as a click, so pop goes the tooltip, and i'm whisked away to my webpage. not the desired result. Ideally I would like to hold down the screen for 3 seconds and then the hyperlink would activate, but i decided that just getting the thing functional would suffice for the time beaing so i tried to include some 'ondblclick' that would trigger a document.location. This worked fine on a web browser again, but had no result on the touchscreen. I decided to abandon this half step because I have read that ondblclick doesn't work in an image map and it isn't my intended result anyway. I have found a lot of javascript and jquery samples that emulate the onHold event that i'm trying to achieve, both on this forum and all over the internet, however these samples are overly complex and are focused on looping an action, such as incrementally increasing a value or zooming or whatever. I just want to redirect the user to another page if they trigger 'onmousedown' for 3 seconds. anybody want to trade some help for a thankyou? Hi there, I found this thread on the forum its from a few years back but the code works, but I can't seem to get the image that appears as you rollover the button to display in the correct place. I'm not sure if its because I'm using tables within tables? Should I recode in divs? Any help is greatly appreciated!! http://www.codingforums.com/archive/...p/t-95847.html hi, i am currently doing a program that will display the image continuously. the image name will be like pic1.jpg , pic2.jpg , pig3.jpg untill pic10.jpg this is my code so far : <html> <head> <script type="text/JavaScript"> var fileName; function display() { fileName = new Array(); for( i=0; i<5; i++) { fileName[i] = new Image(); fileName[i].src = "screenshot_" + i + ".jpeg"; } } display(); </script> </head> <body> </body> </html> but when i run it, it give me infinity loop, can anyone tell me what is the problem of that ? thanks in advance for the reply How do I get a function in the head to turn on or show an image in the body area? I am a struggling noob, but tutorials will not teach me. If I wanted to document.write, or in this case use an alert box, I would not have a question. I feel I understand the functions below, but these are not real world examples of anything, at least that I would ever use. I don't know how to help myself. But I do know, I need to get the part of alert("Hello") changed into something somehow the image will act on, see and display after the 3 second delay. This is the website I got this code from. http://www.w3schools.com/js/js_timing.asp If I can see how to get a function to really do something, would be a big help for me in understanding JS. This is not a school project, my school doesn't offer any programming. I have been at this all day trying to find a tutorial that would help me. Thanks so much for your help. Code: <html>
<head>
<script type="text/javascript">
function timeMsg()
{
var t=setTimeout("alertMsg()",3000);
}
function alertMsg()
{
alert("Hello"); Somehow this has to show my image.
}
</script>
</head>
<body">
<form>
<input type="button"
value="show my Image"
onClick="timeMsg()" />
</form>
<img />
</body>

trying to display an image using an img tag which uses the array value as the image path here is where i set up the array called " img_path " in the head <script type="text/javascript"> var img_path = [ 'images/west/Home.png', 'images/west/Cold.png', 'images/west/Ocean.png', 'images/west/Beach.png' ]; </script> later, in the body, i'm trying to use the array value to splash the image on the web page, like this <img src=" img_path[0] " width="250" height="250"> the result splashes a 250x250 image area on the webpage but not the image (?). why not the image ? i tested the value of "img_path[0]" and it prints out correctly as 'images/west/Home.png' i even cut/pasted this code in and the image splashed out just fine. <img src=" images/west/Home.png " width="250" height="250"> not sure why this won't work? anyone have any suggestions? thanks, Paul weather in Kalispell, MT this morning........not to bad, about 28deg. Merry Christmas and Happy New Year to all. Hi guys I'm really stumped on this, and I haven't been able to find a tutorial online anywhere. I'm trying to create an XML news feed for a company's website I am currently building. I have created the XML, and gotten the text to display perfectly in the HTML by using javascript. Now I want to add a thumbnail image for each news story, to make updating simpler, I wanted the url for the thumbnail to be entered into the XML, from which the javascript could read and then display in the corresponding area in the HTML. Is this even possible? Every tutorial I get when I use the terms "Image" and "Javascript" gives me a tutorial for a gallery or a slideshow which is not what I want at all. Below is the javascript code, followed by the XML code; Code: <script type="text/javascript">

I am sure that you guys can help me solve this problem. Many thanks in advance!! Antonino how long are these numbers? Code: setImageInterval("ad1", 1000, 3);
I know 3 is the max, but the 1000 = how many seconds? Thanks -Tim OVERVIEW of main webpage: when a user logs in, they will be directed to the main page of the website; and will see images displayed according to a value that was stored in the database. the main page preloads an image array: Code: <script type="text/javascript">
var img_FILE = [ 'images/house.png',
'images/car.png',
'images/boat.png'
];
</script>
easy enough the database holds a column of integers that are used to access the proper image in the array. i can successfully pull the integer value i need from the db. what i want to do is when the main page loads, i want the value that was pulled from the database to be used to display the correct image. example: lets say i pulled the value 2 from the db. then i want to display img_FILE[2] on the main page when the page "loads". Code: <body>
<div id="quadrantOne">
<img id="firstImg" src="images/blankImg.png" width="190" height="235" />
<script type="text/javascript">
$.post('imageScript.php', 'data=0', function(data,status){
if (status == 'success') { imgValue = data }
else { imgValue = 'error' }
document.getElementById('firstImg').src=img_FILE[imgValue];
});
</script>
</div>
</body>
i debugged imgValue and it is correctly assigned the value coming from the db. but..........the image won't appear on the main page. any ideas how to get this to work? thanks, Paul Williams Hey all, I am trying to get a code instead of php to display a image from a questionaire results page; Say the url returns; http://localhost/Myoka2/myokaTestResults.php?img=7 the 7 will show score2.png... this works fine with php, here is the code <?php $total = $_GET['img']; if ($total < 7) $total = 1; elseif ($total < 13) $total = 2; elseif ($total < 18) $total = 3; elseif ($total < 20) $total = 4; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Contact Form</title> <script src="rollover.js" type="text/javascript"></script> <link rel="stylesheet" href="http://dl.dropbox.com/u/25307673/myoka/myokaStyle.css" type="text/css" media="screen" /> </head> <body> <span style="color:#6A1E67;font: normal bold 12pt/14pt Arial, Helvetica, sans-serif;margin-left:140px;"> How stressed are you? <h3>SCORES</h3> </span> <img src="http://dl.dropbox.com/u/25307673/myoka/myokaStress/score<?php echo $total; ?>.png" alt="" /><br /> <a href="http://www.facebook.com/myoka.spas?sk=app_128953167177144" target="_blank"> <img src="http://dl.dropbox.com/u/25307673/myoka/myokaFanPage//lastMin.jpg" style="padding-left:0px; padding-top:5px; border:0px" alt="" /> </a> <br/> </body> </html> What i need is this in javascript so that it will work in a iframe :-) I have an image map with 6 areas. Code: <p class="center"><img src="images/car_feature.png" alt="" usemap="#car"/></p> <map id="car" name="car"> <area shape="rect" coords="172,198,195,222" href="#" alt=""/> <area shape="rect" coords="242,79,266,104" href="#" alt=""/> <area shape="rect" coords="293,124,317,149" href="#" alt=""/> <area shape="rect" coords="407,212,431,227" href="#" alt=""/> <area shape="rect" coords="430,300,453,325" href="#" alt=""/> <area shape="rect" coords="565,346,588,370" href="#" alt=""/> </map> I also have 6 DIVs that are hidden and only a single one will appear visible on mouseover of its corresponding image map area. Code: <div id="hidden"> <div class="feature"> Feature 1 </div> <div class="feature"> Feature 2 </div> <div class="feature"> Feature 3 </div> <div class="feature"> Feature 4 </div> <div class="feature"> Feature 5 </div> <div class="feature"> Feature 6 </div> </div> The roadblock I'm running into is the show function in the JavaScript. Code: window.onload = init;
function init() {
var area = document.getElementById("car").getElementsByTagName("area");
var features = document.getElementById("hidden").getElementsByTagName("div");
hide();
function show() {
for(a=0; a < area.length; a++) {

document.getElementById("hidden").getElementsByTagName("div")[a].style.display="block";

function hide() {
for(b=0; b < features.length; b++) {
document.getElementById("hidden").getElementsByTagName("div")[b].style.display="none";
}
}
for(i=0; i < area.length; i++) {
area[i].onmouseover = show;
area[i].onmouseout = hide;
}
}
I'm trying to get it so that if I hover over the first area on the image map, the first hidden DIV will appear, but none of the others. And if I hover over the fourth area, the fourth DIV will appear. I hope this makes sense, and I'd appreciate any and all help towards solving this issue and ending my headache lol So I've got my code ready to generate a random number between a certain range and printing it out in text. What I'm trying to accomplish with this code is to print the actual image as well as the text. I'm aware that there is an error in my document.write line, and that it's not the best solution. I was hoping for some suggestions to change/improve this last bit. Thanks in advance! Code: <html>
