I have a webpage with many images, each of which has a title attribute. When I hover over the image, I want the title text to display in a separate legend element I have created (not as a tiny hover tooltip). I have a mouseover function which works fine - i.e. when I hover over the image the legend changes value. But I want that value to be the title text of the individual image - which I don't know how to access. I have tried …innerHTML = this.title which is obviously incorrect.
[The number of images is large and changing (like an album), so I can't add separate code for each <img> tag. I can use alt or any other <img> attribute to make this work. I'm not wedded to the innerHTML method, either, but am hoping for some simple code to do the trick!]
Please help? Thanks! (FYI, I'm a novice coder.)
<!DOCTYPE html>
<html>
<body>
<h1 id="legend">title appears here</h1>
<div>
<img src="image1.jpg" onmouseover="mouseOver()" title="Breakfast">
<img src="image2.jpg" onmouseover="mouseOver()" title="Lunch">
<img src="image3.jpg" onmouseover="mouseOver()" title="Dinner">
</div>
<script>
function mouseOver() {
document.getElementById("legend").innerHTML = this.title;
}
</script>
</body>
</html>
It looks like you are trying to use this.title to represent the different images? If you want their titles to appear in the <h1> tag you need to pass the information to the function shown below.
<h1 id="legend">title appears here</h1>
<div>
<img src="image1.jpg" onmouseover="mouseOver(this)" title="Breakfast">
<img src="image2.jpg" onmouseover="mouseOver(this)" title="Lunch">
<img src="image3.jpg" onmouseover="mouseOver(this)" title="Dinner">
</div>
<script>
function mouseOver(x) {
document.getElementById("legend").innerHTML = x.title;
}
</script>
I guess its helpful .
But i use Jquery
just need call this code in your <head>

I'm trying to learn/figure out how to successfully play a youtube video within a Bootstrap modal with ekko-lightbox plugin attributes. I've managed to get the Vimeo link to work, but the YouTube link will not retrieve the video, and the button images (external links) do not appear. My work files are saved on my desktop/locally. Do I need to upload my files to an ISP in order for the YouTube and image links to work? I would also like to know how to make the videos play in the modal without having to rely on the internet. That way if I want to present a website concept and there is no internet access, I can still have functionality.
Here is the code as it appears in my index file. Only the Vimeo video link and static waterfall image links work. The button image links do not appear either. Please help!!!

Yes, you need to have your files on a server rather than locally for the Youtube videos and images to work. I experienced this as well and by inspecting the code I saw that the way the javascript was written, those assets are called as file:// rather than http:// when working locally. I thought maybe it had to do with relative links, but it's true even when using absolute URLs.
Since Youtube is dependent on an internet connection, I can't think of a way to load those videos without internet. Try using a locally stored video instead of Youtube video, if you're just concepting something out.
do i have a syntax error? , could it be that im using notepad++?
nothing is happening when i click a thumbnail image
i am new to javascript so that may be the case.
my general idea was to create an event "changeimage" that onclick would change the source of my main image for my thumbnails image to make it bigger.
<head>
<script type="text/javascript">
function changeimage(event)
{
event = event;
var targetElement = event.target;
if (targetElement.tagName == "IMG")
{
document.getElementbyid("Main").src = targetelement.getattribute("src");
}
}
</script>
<meta charset="utf=8">
<style>
#Main
{
height:540px;
width:540px;
}
.imgthmb1
{
height:100px;
width:100px;
}
</style>
</head>
<body>
<img id="Main" src="img/rickroll1.jpg" </img>
<br />
<div id="thumbnail" onclick="changeimage(event)">
<img class="imgthmb1" src="img/rickroll1.jpg" />
<img class="imgthmb1" src="img/rickroll2.jpg" />
<img class="imgthmb1" src="img/rickroll3.jpg" />
<img class="imgthmb1" src="img/rickroll4.jpg" />
<img class="imgthmb1" src="img/rickroll5.jpg" />
</div>
</body>
</html>
Yes, you have a syntax error:
targetElement is spelled targetelement in the following line:
document.getElementbyid("Main").src = targetelement.getattribute("src");
Change it to the following:
document.getElementbyid("Main").src = targetElement.getattribute("src");
On a related note, the following line is extraneous and can be removed:
event = event;
Javascript is case-sensitive.
in place of
document.getElementbyid("Main").src = targetelement.getattribute("src");
write
document.getElementbyId("Main").src = targetElement.getAttribute("src");
Also your html markup has an error:
<img id="Main" src="img/rickroll1.jpg" </img>
should be
<img id="Main" src="img/rickroll1.jpg">
I just found this helpful JS Toggle..
Is it possible to modify this one? I just want to show the actual selected one and hide all others..
<script type="text/javascript">
function toggle(control){
var elem = document.getElementById(control);
if(elem.style.display == "none"){
elem.style.display = "block";
}else{
elem.style.display = "none";
}
}
</script>

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

function show(idToShow, classToHide) {
var classList = document.querySelectorAll('.'+classToHide);
var thisElem = document.getElementById(idToShow);
var wasShown = (thisElem.style.display == "block");
var i = -1;
while (node=classList[++i]) {
node.style.display ="none";
};
if(!wasShown){
thisElem.style.display = "block";
}
}
</script>
</head>

It was a fight to get IE 8 support, document.getElementsByClassName was not supported in that version. It seems that document.querySelectorAll does work in IE 8, but not in quirks mode. Sample code fixed to use this and engage standard mode.
Note: My first quick hack of this used a for loop rather than the while:
for (var i=0;i<classList.length;i++) {
classList[i].style.display ="none";
};
Bonus points if you can spot when this will fail (hover mouse to see answer):
if there's an element in the list with the id length (in which case classList.length will refer to that element, not the length of the NodeList.)
I have searched high and low for an answer and have found similar examples of the problem but the answers do not apply to my scenario. The reality is I am new to this and therefore I don't have the skills to adapt the answers I have found to my problem.
The problem:
I have a Div in which when a thumbnail is clicked the Div image replaces with another image via a JavaScript/jQuery script (I am not sure exactly maybe someone could clarify). This works fine however the problem is the page scrolls back to the top and the user then has to scroll back down to see the image after it has replaced itself.
I have looked online and have found that a return false: in the JavaScript may help however I have looked and return false is already present.
The other option I have looked at using is a JavaScript cookie based solution in which a cookie is sent, and the browser scroll position is maintain by reading the cookie however I cant seem to get that solution to work, I think the issue may be caused because I am hosting locally but I may be wrong...
The third is using a PHP script but I have not found a definitive answer on this method and it also means I am going to have to learn about PHP (something I'm sure I will have to learn in time anyway).
Here is the JavaScript:
<script type="text/javascript">
$(document).ready(function() {
$('.galleryicon').live("click", function() {
$('#mainImage').hide();
$('#cakebox').css('background-image', "url('ajax-loader.gif')");
var i = $('<img />').attr('src',this.href).load(function() {
$('#mainImage').attr('src', i.attr('src'));
$('#cakebox').css('background-image', 'none');
$('#mainImage').fadeIn();
});
return false;
});
});
</script>
Here is the html:
<div class="cakecont">
<div id="cakebox">
<img src="../images/cakes/babycake1.png" alt="Main Image" id="mainImage"/>
<div class="pageinfo2">
<h3>Cake Type 1</h3>
<h6>£2.00</h6>

I have tried to resolve this on my own. This is the first question I have had to ask so far regarding the building of my website, all my learning and remedies to past problems have been served by Google, this one has eluded my search engine skills.
Below I have added all the html for the page in case there may be other script overriding the "new" modified JavaScript -

You can save the current scroll amount and then set it later:
var tempScrollTop = $(window).scrollTop();
..//Your code
$(window).scrollTop(tempScrollTop);
For all who came here from google and are using an anchor element for firing the event, please make sure to void the click likewise:
<a
href='javascript:void(0)'
onclick='javascript:whatever causing the page to scroll to the top'
></a>
Try the code below to prevent the default behaviour scrolling back to the top of the page
$(document).ready(function() {
$('.galleryicon').live("click", function(e) { // the (e) represent the event
$('#mainImage').hide();
$('#cakebox').css('background-image', "url('ajax-loader.gif')");
var i = $('<img />').attr('src',this.href).load(function() {
$('#mainImage').attr('src', i.attr('src'));
$('#cakebox').css('background-image', 'none');
$('#mainImage').fadeIn();
});
e.preventDefault(); //Prevent default click action which is causing the
return false; //page to scroll back to the top
});
});
For more information on event.preventDefault() have a look here at the official documentation.
What you want to do is prevent the default action of the click event. To do this, you will need to modify your script like this:
$(document).ready(function() {
$('.galleryicon').live("click", function(e) {
$('#mainImage').hide();
$('#cakebox').css('background-image', "url('ajax-loader.gif')");
var i = $('<img />').attr('src',this.href).load(function() {
$('#mainImage').attr('src', i.attr('src'));
$('#cakebox').css('background-image', 'none');
$('#mainImage').fadeIn();
});
return false;
e.preventDefault();
});
});
So, you're adding an "e" that represents the event in the line $('.galleryicon').live("click", function(e) { and you're adding the line e.preventDefault();
I had a similar problem getting scrollTop to work after reload of div content. The content scrolled to top each time the procedure below was run. I found that a little delay before setting the new scrolltop solved the issue.
This is cut from wdCalendar where I modified this procedure:
function BuildDaysAndWeekView(startday, l, events, config)
....
var scrollpos = $("#dvtec").scrollTop();
gridcontainer.html(html.join(""));
setTimeout(function() {
$("#dvtec").scrollTop(scrollpos);
}, 25);
....
Without the delay, it simply did not work.
Something to note, when setting the scroll position, make sure you do it in the correct scope. For example, if you're using the scroll position in multiple functions, you would want to set it outside of these functions.
$(document).ready(function() {
var tempScrollTop = $(window).scrollTop();
function example() {
console.log(tempScrollTop);
};
});
$('html,body').animate({
scrollTop: $('#answer-<%= #answer.id %>').offset().top - 50
}, 700);
