I have an image which is set relative to a background image.
I want to call a function on the click but i seem to have been facing a problem.
The hyperlink seems to be working but the function is not being called.
This is how my code looks like
<img src=".." width="100%" height="80" id="ril_logo"/>
<div id="logo-wrapper1">
<img src="..." width="5%" height="45"/>
</div>
<div id="logo-wrapper2">
<a href="#">
<img id="charger" onclick="abc();" src=".." width="4%" height="50" />
</a>
</div>
function abc()
{
alert();
}
Are you 100% sure that the call to abc() is not working? Is there any errors in the console log.
Also you might consider event bubbling. You click on the image and it fires of it's event. This then bubbles to the a href element which then bubbles to the next available element and so forth etc.
Your code could be changed to:
<img id="charger" onclick="abc(); return false;" src=".." width="4%" height="50" />
or
<img id="charger" onclick="return abc();" src=".." width="4%" height="50" />
function abc() { ... return false; }
This will prevent the event bubbling any further than the img onclick function.
Since your img is inside an a tag, the click on the image would cause a click on the a and hence you see the hyperlink working.
If you instead put the onclick on a it would trigger the function call.
try this, and src="imagepath" add your image path
<img src=".." width="100%" height="80" id="ril_logo" />
<div id="logo-wrapper1">
<img src="..." width="5%" height="45" />
</div>
<div id="logo-wrapper2">
<a href="#">
<img id="charger" onclick="abc();" src=".." width="4%" height="50" />
</a>
</div>
<script type="text/javascript">
function abc() {
alert();
}
</script>
Just add your function abc() inside script tags
<script type="text/javascript">
function abc() {
alert("Success");
}
</script>

Here is my HTML:
<img class="image" src="" />
<img class="image" src="" />
<img class="image" src="" />
<button onclick="changeImages()">Change the images</button>
Here is my JavaScript:
function changeImages() {
document.getElementsByClassName("image").setAttribute("src", "images/image.png");
}
How can I make my code so that when I click the button, all those images change?
Thanks
getElementsByClassName() returns a collection of elements which doesn't have methods for applying attributes. You need to iterate through the collection and apply the attributes you want to each of its items. Something like:
document.getElementsByClassName("image").forEach(function(image) {
image.setAttribute("src", "images/image.png");
});
With this function i want to replace a static image with an animated image (gif) on mouseover. But it's not working only on FIRST mouseover. Is there someone that could help me?
JQuery function:
function mouseListener(imageDiv, image, animated, static)
{
$(function() {
$(imageDiv).hover(
function() {
$(image).attr("src", animated);
},
function() {
$(image).attr("src", static);
}
);
});
}
HTML:
<div onmouseover="mouseListener('#would_youDiv','#would_you','images/would_you.gif','images/would_you.jpg');" id="would_youDiv" class="container">
<a href="work.html">
<img id="would_you" class="img-fluid" src="images/would_you.jpg" width="100%" height="100%" />
<div class="overlay">
<div class="text">WOULD YOU</div>
</div>
</a>
</div>
You could make this much easier by generalizing the logic with classes and data elements.
$(document).ready(function() {
$('.hover-image-container').hover(
function() {
//find the image in the container
var $img = $(this).find('img');
//set the src to the animaged src on it
$img.attr('src', $img.data('animated-src'));
},
function() {
//find the image in the container
var $img = $(this).find('img');
//set the src to the original src
$img.attr('src', $img.data('src'));
}
);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container hover-image-container">
<a href="work.html">
<img src="images/would_you.jpg" data-src="images/would_you.jpg" data-animated-src="images/would_you.gif" width="100%" height="100%" />
<div class="overlay">
<div class="text">WOULD YOU</div>
</div>
</a>
</div>
Your mouseListener method is called when the mouseover event occurs, which is when it creates the listener to the event, instead of acting on the event. You don't need to add the listener, since you've already registered the function to be called on mouse over, you just need to do the action you want for that event.
You need to either put that binding somewhere else, or create two methods that are bound to onmouseover and onmouseout.
For example, if you want to go the two methods route (as that's most similar to your current code):
<div onmouseover="mouseOverListener('#would_youDiv','#would_you','images/would_you.gif','images/would_you.jpg');" onmouseout="mouseOutListener('#would_youDiv','#would_you','images/would_you.gif','images/would_you.jpg');" id="would_youDiv" class="container">
<a href="work.html">
<img id="would_you" class="img-fluid" src="images/would_you.jpg" width="100%" height="100%" />
<div class="overlay">
<div class="text">WOULD YOU</div>
</div>
</a>
</div>
And then in your Javascript:
function mouseOverListener(imageDiv, image, animated, static) {
$(image).attr("src", animated);
}
function mouseOutListener(imageDiv, image, animated, static) {
$(image).attr("src", static);
}
You don't need a js function
HTML
<div class="container">
<a href="work.html">
<img class="img-fluid" src="images/would_you.jpg" width="100%" height="100%" onmouseover="this.src='images/would_you.gif'" onmouseout="this.src='images/would_you.jpg'"/>
<div class="overlay">
<div class="text">WOULD YOU</div>
</div>
</a>
</div>
There is an Image coming from server:
<div class="storyDetail">
<img src="img/photo.jpg" height="180" width="300" style="float:left;">
</div>
Now I want to change this image like this through javascript when page loads:
<div class="storyDetail">
<div class="insta-gallery">
<a href="img/photo.jpg" class="tt-lightbox">
<img src="img/photo.jpg" height="180" width="300" style="float:left;"/>
</a>
</div>
</div>
I have tried through Javascript but got nothing because I am not fimilier with Javascript!
I just got the answer with the help of MR.#sinisake.
<!-- Getting Image 'Src' -->
var storyDetailImageSrc= $('.storyDetail').find('img').attr('src');
<!-- Wrapping image with required div(s) -->
$('.storyDetail img').wrap('<a href="'+storyDetailImageSrc+'" class="tt-lightbox">');
$('.tt-lightbox').wrap('<div class="insta-gallery">');
To change text:
Add an id to your div:
<div class="storyDetail" id="storyDetail01">
Define a function:
function changeText {
document.getElementById("storyDetail01").innerHTML =
' <div class="insta-gallery">
<a href="img/photo.jpg" class="tt-lightbox">
<img src="img/photo.jpg" height="180" width="300" style="float:left;"/>
</a>
</div>';
return false; }
Place that function wherever you execute Javascript when loading your page.
If not sure about what you do to that purpose, but the easiest -and dirtiest-, is to add a scirpt at the bottom of the html
<body> -> that's your html page body
--- code code...
<script type="text/javascript">
changeText();
</script>
</body>
I am a total noob, so please go easy.
I am trying to replace one image with a second image while hovering on a different element. My problem is that only the first image is being replaced by the link images. I've give each image an ID, I just am not sure how to apply it.
Thank you in advance for any help you can provide!
Here is what I have so far:
Script:
<script>
function changeimage(towhat,url){
if (document.images){
document.images.targetimage.src=towhat.src
gotolink=url
}
}
function warp(){
window.location=gotolink
}
</script>
<script language="JavaScript1.1">
var myimages=new Array()
var gotolink="#"
function preloadimages(){
for (i=0;i<preloadimages.arguments.length;i++){
myimages[i]=new Image()
myimages[i].src=preloadimages.arguments[i]
}
}
preloadimages("http://www.dxmgp.com/group/images/color_si.jpg", "http://www.dxmgp.com/group/images/bw_si.jpg","http://www.dxmgp.com/group/images/color_dxm.jpg", "http://www.dxmgp.com/group/images/bw_dxm.jpg","http://www.dxmgp.com/group/images/color_tsg.jpg", "http://www.dxmgp.com/group/images/bw_tsg.jpg","http://www.dxmgp.com/group/images/color_image.jpg", "http://www.dxmgp.com/group/images/bw_image.jpg")

How about something like this? Consider you have a div containing image1.png. When you mouse over a hyperlink, you want to replace image1.png with image2.png. Then, when you move your mouse away from the hyperlink, image2.png will once again be replaced with image1.png:
This is your div containing the image:
<div id="image">
<img src="image1.png" />
</div>
This is the hyperlink:
Mouse over to change image
Here are the JavaScript functions that will replace the inner HTML of the div with different images:
<script type="text/javascript">
function mouseOver() {
document.getElementById("image").innerHTML = '<img src="image2.png" />';
}
function mouseOut() {
document.getElementById("image").innerHTML = '<img src="image1.png" />';
}
</script>
Let me know if this is what you are looking for.
I'm creating a simple little slideshow for a site I'm designing for a friend. So far I have it to work just perfectly via clicking images to show / hide the respective image. I'm trying to get it to automatically scroll through the images but it won't seem to work. Here's my code:
<script type="text/javascript">
$(function() // run after page loads
{
$('.slide1t').show();
$('.slide2').click(function()
{
$('.slide2t').show();
$('.slide1t').hide();
$('.slide3t').hide();
$('.slide4t').hide();
});
$('.slide1').click(function()
{
$('.slide1t').show();
$('.slide2t').hide();
$('.slide3t').hide();
$('.slide4t').hide();
});
$('.slide3').click(function()
{
$('.slide3t').show();
$('.slide1t').hide();
$('.slide2t').hide();
$('.slide4t').hide();
});
$('.slide4').click(function()
{
$('.slide4t').show();
$('.slide1t').hide();
$('.slide2t').hide();
$('.slide3t').hide();
});
});
</script>
This is the code i'm using to hide/show images when clicked. Could this be shortened using toggle?
This is what i've tried to get them automatically scrolling:
<script type="text/javascript">
$(function() // run after page loads
{
$('.slide1t').show([1000]),
$('.slide1t').hide(),
$('.slide2t').show([1000]),
$('.slide21t').hide(),
$('.slide3t').show([1000]),
$('.slide3t').hide(),
$('.slide4t').show([1000]),
$('.slide4t').hide()
});
</script>
I've tried other aspects of this same code to try and get it to do something, but to no anvil.
<div id="slideshow">
<div class="text">
<a class="slide1" href="#"><img src="images/1.png" width="240" height="60" /></a>
<a class="slide2" href="#"><img src="images/2.png" width="240" height="60" /></a>
<a class="slide3" href="#"><img src="images/3.png" width="240" height="60" /></a>
<a class="slide4" href="#"><img src="images/4.png" width="240" height="60" /></a>
</div>
<div class="image">
<a class="slide1t" href="#"><img src="images/image1.png" width="525" height="210" /></a>
<a class="slide2t" href="#"><img src="images/image1.png" width="525" height="110" /></a>
<a class="slide3t" href="#"><img src="images/image1.png" width="525" height="170" /></a>
<a class="slide4t" href="#"><img src="images/image1.png" width="525" height="190" /></a>
</div>
</div>
I've looked into the documentation and saw you can use .show([duration],[easing],[callback]) but I don't really know what to input into them.
Thanks all
Are you making a slideshow where you can see to previous and next slide to the left and right of the current slide, or just one slide fading into another?
If it's the latter you can use this very simple code for doing this.
HTML:
<div class="image">
<img src="images/image1.png" />
<img src="images/image2.png" />
<img src="images/image3.png" />
<img src="images/image4.png" />
</div>
CSS:
.image
{
position:relative;
}
.image img
{
position:absolute;
top:0;
left:0;
}
jQuery:
$(function() {
$('.image img:gt(0)').hide(); // to hide all but the first image when page loads
setInterval(function()
{
$('.image :first-child').fadeOut(1000)
.next().fadeIn(1000).end().appendTo('.image');
},5000);
}
This basically shuffles the images like a pack of cards. 5000 (5 seconds) is the interval between fading, 1000 (1 second) is the speed of the fading animation.
For this to work however you must use position:relative on the containing div and position:absolute to position the images on top of each other.
jsFiddle demo
The thing is, .show is async. So your javascript will continue will it does the effect. That's what the third parameter is for, it's an anonymous function that will get called when the effect has finished.
You should look into a jquery plugin, making this things yourself is wasting time. There are hundreds of these plugins so there is always one fitting your needs.
For example: http://www.1stwebdesigner.com/css/fresh-jquery-image-gallery-display-solutions/
You can do this:
$('.image a').each(function (index) {
$(this).show(1000, function () {
$(this).delay(index * 1000).hide(1000);
});
});
FIDDLE DEMO
If you don't want to change your structure much and still want to retain the click function, you can do something like this
This is similar to your original approach but is based in a function and element's siblings instead of doing each image individual. This is optimized for adding new elements easily and retaining functionality. I used a setInterval to loop the animation function as well
HTML (changed slightly)

} else {
elem.hide(1000).parent().children('a').first().show(1000);
}
}
var loop = self.setInterval(function () {
autoChangeSlide()
}, 5000);
You can combine my solution with Dolchio's to make it particularly awesome
