I tried one of the examples here to load the content in the div, but apart from displaying the image, it doesn't show anything. Where I'm going wrong?
File ajax1.js:
function General_Refresh(url,div){
//Showing the load image (pay attention to /> of <img
document.getElementById(div).setInnerXHTML('<span id="caric"><center><img src="http://website.name/images/ajax-loader.gif" /></center></span>');
var ajax = new Ajax();
ajax.responseType = Ajax.FBML;
ajax.ondone = function(data) {
//Hide the loading image
document.getElementById('caric').setStyle('display','none');
document.getElementById(div).setInnerFBML(data);
}
//If there are errors re-try
ajax.onerror = function() {
General_Refresh(url,div);
}
ajax.post(url);
}
File quote.html:
<script src="http://website.name/scripts/ajax1.js" type="text/javascript"></script>
<script type="text/javascript">
<!--
General_Refresh("http://website.name/quote.php","quote");
//-->
</script>
<div id="wrapper">
<div id="quote"><strong>this</strong></div>
</div>
</div>
There was nothing wrong with FBJS/Ajax. It was an error in quote.php.

I want to display a gif image until the website is completely loaded.
Once I click button (onclick=window.open) a new page opened but is blank and the gif is only appearing once the website is loaded.
I want once clicking the button a new page opened and showing immediately the gif and disappear once the page is loaded
Can anyone help me, what I’m doing wrong or what is missing to load the gif when the page is loading? Here is my code, thank you so much
land.php file:
<button type="button"
onClick="window.open('./gremo.cfm ',
toolbar=no,
menubar=no,
scrolling=yes,
scrollbars=yes
')">
</button>
gremo.php file:
<head>
<script type="text/javascript">
function showHide(elementid){
if (document.getElementById(elementid).style.display == 'none'){
document.getElementById(elementid).style.display = '';
} else {
document.getElementById(elementid).style.display = 'none';
}
}
window.onload = function () { reSizeTextarea(); showHide('loadingd'); }
</script>
</head>
<body>
<div id="loadingd" align="center">
<br/><br/><br/><img src="./loading.gif">

Note that when you are running locally, resources are loading fast.. very fast
Don't forget to use your developer tools and configure network throttling (to simulate a slower connection). That should simulate a "real" scenario and let you test your code better
Here is a screenshot from chrome... enjoy!
When you have a lot of content, it will take time to load. The image will show and than hide when the onload event happens. Now run it again, the content is cached and loading will take no time at all.
So load time depends on what there is to load/render, how it is loaded, and if it is cached or not.
window.onload = function () {
document.getElementById("loading").remove()
document.querySelector(".content").removeAttribute("hidden")
}
[hidden] {
display: none
}
#loading {
width: 300px;
}
<img id="loading" src="https://media.giphy.com/media/3o7bu8sRnYpTOG1p8k/source.gif" />
<div class="content" hidden>
<img src="http://placekitten.com/200/200" />
<img src="http://placekitten.com/100/100" />
<img src="http://placekitten.com/300/300" />
<img src="http://placekitten.com/400/400" />
<img src="http://placekitten.com/500/500" />
</div>
In your example, you have nothing that takes time to load other than the loading image. So as soon as your image is loaded, the window.onload is triggered. That is why it flashes.
If you want the image to show, you can add some logic saying if I have not been here for X seconds, than wait....
var startTime = new Date()
window.onload = function () {
var loadTime = new Date()
var diff = loadTime - startTime;
if (diff > 5000) {
toggleLoad()
} else {
window.setTimeout(toggleLoad, 5000 - diff)
}
}
function toggleLoad () {
document.getElementById("loading").remove()
document.querySelector(".content").removeAttribute("hidden")
}
[hidden] {
display: none
}
#loading {
width: 300px;
}
<img id="loading" src="https://media.giphy.com/media/3o7bu8sRnYpTOG1p8k/source.gif" />
<div class="content" hidden>
<img src="http://placekitten.com/200/200" />
<img src="http://placekitten.com/100/100" />
<img src="http://placekitten.com/300/300" />
<img src="http://placekitten.com/400/400" />
<img src="http://placekitten.com/500/500" />
</div>
To ensure the loading gif loads fast, on the parent page, you probably want to preload it
var img = new Image()
img.src = "your.gif"
I am trying to get an alert if I chose a certain picture for example:
HTML:
<div id="main">
<img id='pr' style="width: 500px;height: 600px;" src="">
</div>
Then I manually chose a picture that goes into 'main' and changes it src JQUERY:
<script type="text/javascript">
$('#paperb').click(function()
{
$('#pr').attr("src", "http://www.cliparthut.com/clip-arts/1008/paper-stack-
clip-art-1008442.jpg");
}); </script>
Than there comes the JS that fails:
<script type="text/javascript">
if (getElementById('#pr').attr('src' ,'https://i.redd.it/2u0y0z5i12py.png')
{
alert('euirhzeurhzu')
}
</script>
But this script wont work. Is it possible to get an alert from this?
What do I need to change so I can get an alert?
Thank you.
If you have multiple images & want to do some action when src value is changed for certain images, then try below;
$('#pr').on('load', function (e) {
console.log("Image Path: ", e.target.src);
if(e.target.src == "https://i.redd.it/2u0y0z5i12py.png") {
//do action a
} else if(e.target.src == "https://...bike.png") {
//do action b
}
});
Replace
if (getElementById('#pr').attr('src' ,'https://i.redd.it/2u0y0z5i12py.png')
with
if (getElementById('#pr').attr('src') === 'https://i.redd.it/2u0y0z5i12py.png')
Also the other problem is that your if statement is not declared in an event handler. So it will run only once when the script first loads. You need to place it under an event after which you want to execute it. E.g.
<script type="text/javascript">
$('body').on('click','#pr',function(){
if ($('#pr').attr('src') === 'https://i.redd.it/2u0y0z5i12py.png') {
alert('euirhzeurhzu');
}
});
</script>
Edit: Here's a working snippet.
$('body').on('click','#pr',function(){
if ($('#pr').attr('src') === 'https://i.redd.it/2u0y0z5i12py.png') {
alert('euirhzeurhzu');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main">
<img id='pr' style="width: 500px;height: 600px;" src="https://i.redd.it/2u0y0z5i12py.png">
</div>
I am currently working on my school project website and I am really having a hard time coding.
So in my website I made an image slider and I wanted the images to be linked to another page, like if the user clicked the image they will be redirected to another page that contains information regarding the image they clicked. I also wanted a hover text when the mouse is pointed on the image that shows the title of it.
I tried to search and to watch videos on how to link images but nothing works.
Here's my code:
<script type="text/javascript">
<!-->
var image1=new Image()
image1.src="e.jpg"
var image2=new Image()
image2.src="g.jpg"
var image3=new Image()
image3.src="h.jpg"
//-->
</script>
<style type="text/css">
#gallery {
width: 100%;
height: 100%;
}
#gallery img {
width: 55%;
}
</style>
<DOCTYPE!html>
<html>
<body>
<center>
<div id="gallery">
<img src="e.jpg" name="slide" alt="Track race">
<script type="text/javascript">
<!--
var step=1
function slideit(){
document.images.slide.src=eval("image"+step+".src")
if(step<3)
step++
else
step=1
setTimeout("slideit()",2500)
}
slideit()
//-->
</script>
</div>
</center>
</body>
</html>
onclick on a image to navigate to another page using Javascript
3rd best answer:
I'd set up your HTML like so:
<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" id="bottle" />
Then use the following code:
<script>
var images = document.getElementsByTagName("img");
for(var i = 0; i < images.length; i++) {
var image = images[i];
image.onclick = function(event) {
window.location.href = this.id + '.html';
};
}
That assigns an onclick event handler to every image on the page (this may not be what you want, you can limit it further if necessary) that changes the current page to the value of the images id attribute plus the .html extension. It's essentially the pure Javascript implementation of #JanPöschko's jQuery answer.
I just want to understand more of the previous post from this site and w3school, where the loading image/icon is displayed while loading the page content.
Here's the script I've re-used -
<script type="text/javascript">
$(document).ready(function(){
$('#Btn_5').click(function() {
$('#spinner').show();
});
});
</script>
Here's the form section and script -
<form id="iform" method="get" action="">
Search: <input type="text" id="search_box"><br>
<div id="Btn_5" class="btn">Search</div>
</form>
<br>
<div id="spinner" class="spinner" style="display:none;">
<img id="img-spinner" src="http://www.w3schools.com/jquery/demo_wait.gif" alt="Loading"/>
</div>
<br>
<body>
<script type="text/javascript">
...
$( "div.content:contains('"+ filterarray[i] +"')").css( "display", "block" );
$("#results").append(results);
...
</script>
<div id="results"></div>
</body>
I have this loading icon spinner, but it doesn't work after the results are displayed. It only spins when button (Btn_5) is clicked and loading icon disappears when the page reloads.
QUESTION: I want to run the loading/spinning icon from the start of the button click until all content under the are displayed. Is there a way to do this?
I hope I am understanding correctly.
But, you want to show the spinner before:
$("#results").append(results);
and hide it after the results are appended?
If that is the case, then you should just be able to do;
$('#spinner').show(); //show spinner
$( "div.content:contains('"+ filterarray[i] +"')")
.css( "display", "block" ); //not sure what you are doing here
$('#results').append(results); //append results, which you have not defined in example
$('#spinner').hide(); //hide spinner
Use that as
//before load
window.onbeforeunload = function () { $('#spinner').show(); }
//after loaded
$(window).load(function() {
$('#spinner').hide();
});
I've been looking around much today and spend a few hours trying to get something done. For a client I am creating a slideshow with a lightbox when clicked on an image. The slideshow and lightbox both work, but I don't get the right image in the lightbox yet.
This is the code that loads the slideshow and when clicked on an image opens the lightbox.
(The images for the slideshow get loaded by a php script and turned into a Javascript array)
<script type="text/javascript">
var curimg=0;
function rotateimages(){
document.getElementById("slideshow").setAttribute("src", "images/"+galleryarray[curimg]);
curimg=(curimg<galleryarray.length-1)? curimg+1 : 0;
}
window.onload = function(){
setInterval("rotateimages()", 1000);
}
</script>
<div style="width: 170px; height: 160px">
<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style. display='block'">
<img id="slideshow" src="" />
</a>
<div id="light" class="white_content">
<img id="lightImg" src="" />
<script>
var image = document.getElementById("slideshow").src;
document.getElementById("lightImg").setAttribute("src", image);
</script>
I now try to create a variable named "image"and let this contain the src of the current image in the slideshow. So I can load this to the image in the lightbox.
Hopefully some one can give me some usefull tips. I am pretty new in the Javascript language.
The script for the slideshow came from: http://www.javascriptkit.com/javatutors/externalphp2.shtml

These days there really is no excuse for using obtrusive Javascript (Stuff inside your HTML attributes, ideally it should be in an external file. http://en.wikipedia.org/wiki/Unobtrusive_JavaScript).
I have done you the favour of cleaning up your code a bit, and changed it where you seemed to be going wrong. As DotNetter has already pointed out it would be sensible to use jQuery in this instance, as it really does simplify things. However, I'm going to assume that for some reason you want it in plain js. Below is a simplification of the code that you posted with the correct change.
<style type="text/css">
.wrapper {
width: 170px;
height: 160px;
}
</style>
<script type="text/javascript">
var curimg=0;
function rotateimages(){
document.getElementById("slideshow").setAttribute("src", "images/" + galleryarray[curimg]);
curimg=(curimg<galleryarray.length-1)? curimg+1 : 0;
}
window.onload = function(){
setInterval("rotateimages()", 1000);
document.getElementById("slideshow").onclick = function () {
var imageSrc = document.getElementById("slideshow").src;
document.getElementById("lightImg").setAttribute("src", imageSrc);
document.getElementById('light').style.display = 'block';
document.getElementById('fade').style.display = 'block';
}
}
</script>
<div class='wrapper'>
<img id="slideshow" src="" />
<div id="light" class="white_content">
<img id="lightImg" src="" />
</div>
</div>
Before, you were getting the src of the current image when the page loaded, you need to be getting the src of the image when the user clicks on the
