Is it possible to specify ¶mters=whatever type stuff for <iframe> in CSS?
I want to embed multi-track audio from archive.org. So for example, something like this:
<iframe src="https://archive.org/embed/art_of_war_librivox&playlist=1&list_height=200" width="100%" height="200"></iframe>
These bits are easy to do in CSS
.multitrack iframe {
width: 100%;
height: 200px;
}
But what about &playlist=1&list_height=200? Does that have to be done in HTML every time? I want to get it down to just:
<div class="multitrack">
<iframe src="https://archive.org/embed/art_of_war_librivox"></iframe>
</div>
I want to embed it on AO3.org, which is extremely stringent about what we're allowed to use. So please no "use this entirely other tool to solve your problem!" this time. If I can't do it with CSS, I'm pretty sure I can't do it at all.
I don't think there is a CSS based solution to your problem.
Your &playlist=1&list_height=200 is telling the iframed site iself (via GET request) that you want the first playlist and a playlist height of 200px to be rendered.
is there a way with javascript/jquery to prevent images from loading? I am building a slideshow from a html list with images. So I would like to collect all the src data and then prevent the images from loading. So later when the user really needs the image I would load it then.
I found some lazy loading script on google but couldn't find the way they prevent images from loading.
Thanks in advance.
Edit1:
It seems from the answers that it's not possible to use javascript to prevent images from loading.
Here is a script that does lazy loading. Could anybody explain how it works? It seems when javascript is off it just loads the images normaly and when it's on it will load them when you scroll to their location.
You can wrap the image in a noscript tag:
<noscript>
<img src="foo.jpg"/>
</noscript>
All browsers that has JavaScript enabled will ignore the image tag so the image won't load.
If you render the HTML on the page, even if it's hidden, it's going to load. If you want images to load only when they're needed, you're going to have to dynamically set the source (src) on the image tag in javascript.
Edit 1: The script you referenced merely checks to see how far you've scrolled the page down and then determines which images are visible (or almost visible) by checking their top -- see the $.belowthefold and $.rightoffold extensions.
The example works great when the images are all the same size because their containers can also be the same size and you won't get any odd page resizing behavior when you lazy load them. If your images' heights and widths vary, you may get some odd results.
Edit 2:
<script type="text/javascript" charset="utf-8">
$(document).ready( function() { $("img").removeAttr("src"); } );
</script>
<img src="Chrysanthemum.jpg" />
<img src="Desert.jpg" />
<img src="Hydrangeas.jpg" />
<img src="Jellyfish.jpg" />
<img src="Koala.jpg" />
<img src="Lighthouse.jpg" />
<img src="Penguins.jpg" />
<img src="Tulips.jpg" />
Store the URLs somewhere else, then set all image URLs to some dummy image (empty, transparent, "loading data...", whatever). When an image should be displayed, use JS to set the src attribute and the browser will fetch it.
Well with Prototype you can do something like this I guess:
var unloaded = [];
$$('img.noload').each(function (image) {
unloaded.push(image);
image._src = image.src;
image.src = '';
});
To load all of them:
unloaded.each(function (image) {
image.src = image._src;
});
To load the first one:
function loadImage (image) {
image.src = image._src;
}
loadImage(unloaded.shift());
Well I hope you got the idea.
Just do not include the img tag in your original HTML, generate it on the fly using DHTML as you need it. You can also put a fake url to image in the img tag and replace it with the real one dynamically.
On the side note - what's the point. All you are trying to do here is to build another caching mechanism over the existing one. Leave caching to browsers, they are pretty good at this
You can use the portion below to replace all image tags with a dummy file (for example, an 1x1 transparent gif). The url's are stored in a array for later reference.
$(document).ready(function(){
var images = new Array();
$("img").each(function(i){
images[i] = this.src;
this.src='blank.gif';
});
});
I don't recommend this solution, for many reasons (like it ruins your page if you don't have Javascript enabled, screen-readers etc), but its a possibility...
You could change the IMG tag so that it hijacks a different attribute, like ALT (LONGDESC, or TITLE too):
Then use Javascript to update the SRC attribute with the ALT value as you need to.
So thats one way, and not a good one. I think the only real approach is to dynamically generate the proper IMG tag as needed via Javascript and not publish it with the HTML (this too has implications for non-JS browsers etc)
This article shows some tests using both css background and img tags on a set of standard browsers.
In my personal experience the PictureFill by Scott Jehl is the best solution I've ever used to deal with image resolutions and sizes for mobile devices.
I know this is an old question, but it took me a while to figure out how to accomplish what I wanted to. This is the top result on DuckDuckGo so I think it's worth posting here.
This little snippet will prevent imgs, embeds and iframes from being loaded and will manually load them later when needed.
One caveat: objects that are loaded too fast for JQuery/JavaScript to catch them are still loaded, and the script still removes them.
Since this is intended to decrease load time this should not be a problem though.
Fiddle
loadObjects = function() {
/* LOAD OBJECTS */
$("img, embed, iframe").each(function() {
var obj = $(this);
obj.attr("src", obj.data("objsrc")).ready(function() {
obj.fadeIn(1000, "linear").prev(".loading").fadeOut(750, "linear", function() {
$(this).remove();
});
});
});
}
$(document).ready(function() {
/* *** PREVENT OBJECTS FROM LOADING *** */
$("img, embed, iframe").each(function() {
var obj = $(this);
obj.data("objsrc", obj.attr("src"));
obj.hide().attr("src", "").before("<span class=\"loading\"></span>");
});
});
You can also wrap the image in a template tag:
<template>
<img src="foo.jpg"/>
</template>
Browsers will not try to load it.
The answer to this problem is very easy via insertAdjacentHTML() which lets you add HTML when you like, in this case on button click:
function LoadImages(){
document.body.insertAdjacentHTML('afterEnd','<img src="one.jpg" alt="" height="100" width="100"> <img src="two.jpg" alt="" height="100" width="100">');
}
The HTML...
<button onclick="LoadImages();">Click to load images</button>
super css noob here.
I'm using a wordpress plugin called visual composer which allows you to name a Row (it's like a block element) with a Row ID or a Class name. I'm trying to have it so when a user hovers over this row and when they click it, this clicking will simply take them to another page within my website.
It allows for an area to have the css for this class or ID that I can associate with the tag, but after searching I'm either searching the wrong thing or can't find it but I am looking for the css that would allow me to do this!
You can't only use css to link to other page, you need javascript. For example the class name is linkPage:
document.getElementsByClassName('linkPage')[0].onclick = function(){
location.href= 'some url...'
}
<div class="linkPage">linkPage</div>
You'd need to inject a bit of JS into the theme that listens on window for a click with the desired ID or class, then call window.location.href = URL or something of that nature.
CSS doesn't have the power to cause browser location changes.
CSS
CSS (Cascading Style Sheet), as its name states, defines a set of rules and properties for an HTML page you wish to style (stuff like colors, size, asf); and user interaction (even as minor as pointing to an URL) are not part of its scope.
Basic
Talking about a giant like WordPress and a strong plugin such as Visual Composer, extremely old and standard features like link/image/table asf are always to be found. You may have a look at visual composer's "Raw HTML" feature (https://vc.wpbakery.com/features/content-elements/) in combination with a regular "a" tag (http://www.w3schools.com/tags/tag_a.asp).
Editable
Asking how page linking can be achieved through editing of a CSS file, then you might as well look into different editable content types of the plugin - such as HTML or JS.
Click on table row
Best approach to have table cells/rows clickable would be by the use of JavaScript; see Adding an onclick event to a table row
Link using jQuery and Javascript (easier method):
$(".link").click(function(){
window.location.replace('https://www.example.com');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="link">link</div>
<div class="link">link</div>
<div class="link">link</div>
<div class="link">link</div>
<div class="link">link</div>
Link using pure Javascript (harder method):
x = document.querySelectorAll('.link').length;
y = 1;
while (x => y) {
document.getElementsByClassName("link")[y].onclick = function() {
window.location.replace("https://www.example.com");
};
y++;
}
<div class="link">link</div>
<div class="link">link</div>
<div class="link">link</div>
<div class="link">link</div>
<div class="link">link</div>
I'm trying desperately to make the link on a linked image work but whenever I click on the link, my browsers (Chrome & Firefox) just tell me they are connecting to the page and I get a continuous spinning image as if the browser were doing something. The link works perfectly if I open in another tab.
The div in question is coded and styled in a Wordpress page. I am making changes to another developer's work for a customer.
Here's the div:
<div style="position: absolute; top: 645px; left: 80px; width: 150px;">
<a href="http://themoneycouple.com/?p=4681" target="_top" style="display:inline-block">
<img src="http://themoneycouple.com/wp-content/uploads/2013/10/kit-history.png" alt="Toolkit History Link" width="150" height="170" style="position:relative; display:block; z-index:999999999999;" />
</a>
</div>
And here's the page it's on: http://themoneycouple.com/resources/love-and-money-kit/
I've tried changing the z-index on every element in multiple ways, tried changing the link target in every way possible, changed display settings, etc.
One last note, there are lots of iframes on this page and I'm not sure if those are messing things up somehow. Massive thanks for any help.
It looks like the URL for that HREF is trying to load a page as a modal using the fancybox protocol. Is this what is expected?
Does that page ID exist? It looks URL looks different from the other page URLs on the site.
There is a jQuery function that targets every IMG tag w/ an A tag and applies a class of "fancybox". Modify the specificity of this function to exclude the last item in the gallery. Better yet, create a new class and add it to the elements that should have the fancybox functionality. The same issue happens on other pages where the HREF goes to a page instead of opening an image.
Current jQuery function:
var thumbnails = jQuery("a:has(img)").not(".nolightbox").filter( function() { return /\.(jpe?g|png|gif|bmp)$/i.test(jQuery(this).attr('href')) });
thumbnails.addClass("fancybox").attr("rel","fancybox").getTitle();
I think I found the link you mean and it has a fancybox class on it, so I presume it is trying to open a fancybox javascript plugin popout for your link.. which is a redirect and failing to do so, since I can right click the link and go to open in new tab and it works.
I need to have the links within my Content Editor Web Part open in the parent frame. The links are a part of the page the iframe is loading. I am editing the Home Page of the SharePoint site and cannot add a tag to the page. Here is my code:
<div style="overflow:hidden; width: 800; height:200; position:absolute; left:-170px; top:0px;">
<iframe src="/News/Pages/Default.aspx#OuterZoneTable" style="overflow:hidden; width:100%; height:550;" frameborder="0" marginheight="0" marginwidth="0" scrolling="no">
</iframe></div>
The widths and heights are different because I am offsetting the page to show a particular location in the page.
Unless I'm missing something about your requirements, wouldn't a TARGET attribute set to _top (or _parent) on your anchors be sufficient?
You'd need to edit the HTML source to accomplish this, so maybe you're asking if there's a way to set that behavior using the Content Editor WYSIWYG controls -- which I don't believe there is.
Another idea would be to use scripting to set the attribute values via the DOM. For example, if you had jQuery in play on your page of links, you could do something like:
$("#OuterZoneTable>a").attr("target","_top");
That example assumes the links you want to change are contained in an element with the HTML id of "OuterZoneTable".
