Changing IFRAME height dynamically - javascript

How is it possible to fix the height issue of Google Trend charts dynamically.
For an example take a look on the output of following code.
<iframe width="600" height="320" src="http://www.google.com/trends/fetchComponent?hl=en-US&q=css-showcase&content=1&cid=TIMESERIES_GRAPH_0&export=5&w=600&h=320" style="border: none;"></iframe>

i didn't test it, but this could work.
function autoResize(id)
{
var newheight;
newheight=document.getElementById(id).contentWindow.document.body.scrollHeight;
document.getElementById(id).height=newheight + "px";
}
<iframe id="frame1" onload="autoResize('frame1')" ... >

set id for iframe
and in jquery set height
$('#idval').css('height','800px');

some part of the image becoming invisible while using it on html page

I am talking about the image in the second section of link on this HTML page.
and here is the link of the original image.
when you inspect the HTML page you can see, I am using the same image as the link given, and still, the hand in the image is not showing, I tried to do resizing and everything on inspect so that the hand in the image become visible but not working. I thought it is an issue of z-index but I checked everything z-index is fine, the border part of the hand is visible.
I just saw with different Mac and safari browser the image is showing up with hand but in my system, Linux, and chrome browser the image is showing up without the hand.
<div class="col-lg-4 is-animated">
<img src="assets/images/2sec.svg" class="img-fluid" alt="">
</div>
Have a try using <object> tag:
<object type="image/svg+xml" data="https://www.thealphateam.digital/demos/pando/assets/images/2sec.svg">
#Progu, Thanks for your answer, your answer was working but I started facing another problem with my javascript code, scrolling stopped working when I used an object tag to display image...
so I searched for more alternatives to display images apart from an image tag, and I found the Iframe method, it worked awesomely. but still, if someone knows why this was happening and can display it with the image tag can answer.
<iframe frameborder="0" scrolling="no" width="100%" height="100%"
src="assets/images/2sec.svg" name="imgbox" id="imgbox">
<p>iframes are not supported by your browser.</p>
</iframe><br />
Change the inline style style margin-left value.
<iframe frameborder="0" scrolling="no" width="100%" height="100%" src="assets/images/2sec.svg" name="imgbox" id="imgbox" style="margin-left: 256px;">
And also the svg width="100%" and height="auto"
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="auto" viewBox="0 0 540 471" fill="none">

How do I make iframes responsive without using div?

I learnt from this post (Making an iframe responsive) that make an iframe responsive by adding a container with a class around the iframe, for instance,
<div class="intrinsic-container">
<iframe width="560" height="315" src="https://www.youtube.com/embed/I4YoBuJCbfo" frameborder="0" allowfullscreen></iframe>
</div>
Is there possible to embed <iframe>...</iframe> directly in my posts (without using <div>...</div>)? And I tried these solutions, but all of them don't work.
PS: I use two columns layout in WordPress. The ratio of video can be 16:9 (from YouTube), 4:3 (from Tencent), etc. Here is a temporary demo.
If you can use viewport units that is doable without an extra wrapper element.
Full page width:
iframe {
width: 100vw;
height: 56.25vw; /*16:9*/
}
<iframe width="560" height="315" src="https://www.youtube.com/embed/I4YoBuJCbfo" frameborder="0" allowfullscreen></iframe>
Half page width:
iframe {
width: 50vw;
height: 28.125vw; /*16:9*/
}
<iframe width="560" height="315" src="https://www.youtube.com/embed/I4YoBuJCbfo" frameborder="0" allowfullscreen></iframe>
The key here is the height and width ratio you want to keep. I took the liberty of using jQuery instead of javascript to do this. The code triggers upon clicking the button. It calculates the width and height ratio of the iframe and adapts both to your needs (in this case I assumed you wanted it to fill the containers width).
You'll probably want to loop through all videos if you have multiple on one page and run the code on window resizing and page-loading.
Here is the JSFiddle
Hope it helps :)
html
<iframe id="iframe" width="640" height="360" src="https://www.youtube.com/embed/4SDVkdcO8ts" frameborder="0" allowfullscreen></iframe>
<button id="button" style="float: left">Click me!</button>
jQuery
$(document).ready(function(){
$("button").click(function(){
var ratio = $("#iframe").height() / $("#iframe").width();
$("#iframe").width("100%");
var newWidth = $("#iframe").width();
$("#iframe").width(newWidth);
$("#iframe").height(newWidth*ratio);
$("button").text("resize the window and click me again!");
});
});
Use bootstrap class to make iframe responsive.
<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" allowfullscreen
src="//www.youtube.com/embed/zpOULjyy-n8?rel=0" >
</iframe>
</div>

anchor tag is not working with image http://www.smoothdivscroll.com/demo.html

actully i m trying to use anchor tag with this slider image
<div class="smallsliderdiv">
<p class="smallslider"> Top websites </p>
<div id="makeMeScrollable">

</div>
<div>
but its not working images are not getting showed when i do like this? i dont want the alternative way .. what is the problem with this slider?? last two images have no problem .. when i remove anchor tag all is fine but i need this. Thank you.
This is working fine with html but not with the slider i m using which is http://www.smoothdivscroll.com/demo.html use js and css from this site
and i am using for each loop for echoing image address and link address .
This is how I would do it, since your .js or .css slider files probably has an issue with wrapping the images with an anchor tag, so instead of wrapping the images with an anchor you can add an onclick event to the img and have the javascript link the image. and manually change the cursor to a pointer in the CSS.
See fiddle for example: https://jsfiddle.net/DIRTY_SMITH/7oe5kh9L/47/
html
<img onclick="image1()" width="400px" height="300px" src="http://lorempixel.com/400/200/"/>
CSS
#makeMeScrollable > img:hover{
cursor: pointer;
}
Javascript
function image1(){
window.location.href = 'www.google.com';
}

Wrap href around an iframe

I want to wrap an href around a vimeo or youtube video and prevent the default playback click events of the embed and just go to the href. Does anyone know how to do this?
<a href="http://tumblr.com" target="_blank" class="linkwrap">
<iframe width="420" height="315" src="https://www.youtube.com/embed/5Xbs60BMeRU" frameborder="0" allowfullscreen></iframe>
</a>
html
<a href="http://tumblr.com" target="_blank" class="linkwrap">
<div class="blocker"></div>
<iframe width="420" height="315" src="https://www.youtube.com/embed/5Xbs60BMeRU" frameborder="0" allowfullscreen></iframe>
</a>
css
.linkwrap { position:relative; display:inline-block; }
.blocker { position:absolute; height:100%; width:100%; z-index:1; background:rgba(255,0,0,0.5); }
.linkwrap iframe { z-index: 2; }
jsfiddle - here
Use a div as overlay and surround it with your a tag. Read this article to see how to implement the div and using opaque for youtube: https://stackoverflow.com/a/4788044/4375900
I think with this info you should be possible to do what you want to do.
For cross browser support use this:
<div style="position:relative;">
<iframe width="420" height="315" src="https://www.youtube.com/embed/5Xbs60BMeRU" frameborder="0"></iframe>
<img src="https://upload.wikimedia.org/wikipedia/commons/c/ca/1x1.png" width="420px" height="315px">
</div>
I feel like it's worth mentionning that in my case, adding pointer-events: none on the iFrame allowed the link to work with a structure looking like this
<div>
<a href="#test">
<iframe [ATTRIBUTES]></iframe>
</a>
</div>

Youtube video shows on click of image

I've looked at a few implementations of this and so far none have worked so I'm resorting to posting. The concept is: a placeholder image which once clicked changes into the video and autoplays.
Current HTML:
<div id="ytvideo" style="display:none;">
<iframe width="939" height="528" id="ytvideo" frameborder="0" allowfullscreen></iframe>
</div>
<img class="aligncenter size-full" id="homevideo" alt="placeholder" src="/wp-content/uploads/2013/10/placeholder.jpg" width="940" height="548" />
Current JS:
jQuery(document).on('click','#homevideo',function(e){
jQuery('#ytvideo').show();
jQuery('#homevideo').hide();
jQuery('#ytvideo').attr("src","www.youtube.com/embed/[myvidid]?autoplay=1");
jQuery("#ytvideo").attr('src', jQuery("#ytvideo", parent).attr('src') + '?autoplay=1');
});
I've looked at trying to reload the iframe but that doesn't seem to work.
Any ideas?
MARKED: FIXED
You forgot the protocol - www.youtube.com/… would link to folder on the server.
With protocol it works fine – I’d suggest creating the whole iframe dynamically though, because with an empty src attribute at the beginning it would load the same page it is embedded in.
<div id="ytvideo" style="display:none;"></div>
<!-- replaced your image with a span here for fiddle -->
<span id="homevideo" data-vidid="mbOEknbi4gQ">click me</span>
$(document).on('click','#homevideo',function(e){
$('#homevideo').hide();
$('#ytvideo').html('<iframe width="939" height="528" id="ytvideo" frameborder="0" allowfullscreen src="http://www.youtube.com/embed/'+$(this).attr("data-vidid")+'?autoplay=1"></iframe>').show();
});
http://jsfiddle.net/HuVqm/
As discussed in one of the comments, you can get both the img and the video from the api.
This would be good if you didn't want to maintain the image, just wanted it to pull through from YouTube. (However I am not sure that YT provide an image as large as 939 so in your case you might still want to use your own image). I have put in a random channel name 'RIDEChannel' feel free to change that with your channel name.
<div id="vid"></div>
$.getJSON("http://gdata.youtube.com/feeds/api/users/RIDEChannel/uploads?max-results=1&v=2.1&alt=jsonc&callback=?", function (myvid) {
var vid = $("#vid");
$.each(myvid.data.items, function (i, item) {
vid.append("<img width='300' height='250' src='" + item.thumbnail.hqDefault + "'>");
$(document).on("click", "#vid img", function (event) {
vid.append("<iframe width='300' height='250' src='http://www.youtube.com/embed/" + item.id + "?autoplay=1' frameborder='0'></iframe>");
$(this).hide();
});
});
});
So the problem laid with the youtube url missing the http:// prefix and also for the fact that the iframe name was the same as the div it was enclosed in. (How silly of me) Thus it was attaching the SRC to the div, not the iframe.
Working DEMO
Try this,
First you cannot have same id for more than one elements <div id="ytvideo" and <iframe id="ytvideo"
[myvidid] in http://www.youtube.com/embed/[myvidid]?autoplay=1 should be replaced with the id of the video
html
<div id="ytvideo1" style="display:none;">
<iframe width="939" height="528" id="ytvideo" frameborder="0" allowfullscreen></iframe>
</div>
<img class="aligncenter size-full" id="homevideo" alt="placeholder" src="http://thefabweb.com/wp-content/uploads/2012/12/6191814472_fa47c79b67_b-900x600.jpg" width="940" height="548" data-vid='DBNYwxDZ_pA'/>
code
jQuery(document).on('click','#homevideo',function(e){
jQuery('#ytvideo1').show();
jQuery('#homevideo').hide();
jQuery('#ytvideo').attr("src","http://www.youtube.com/embed/"+$(this).data('vid')+"?autoplay=1");
});
If you have more than 1 video, it could be useful to store the url to the video in the html and use a class instead of an id.
Also, if you put the preview image into the background, behind the video, it will stay there until the iframe has loaded, reducing that "flickering" effect when clicked.
I also restructured the markup a bit to reduce redundancy, here I specify the size of the video and the video id only once.
Also, you should use jQuery's .one('click') instead of .click(), since you want that event listener removed after it has fired the first time.
html:
<div class="ytvideo"
data-video="73sgatbknvo"
style="width:939px; height:528px; background-image:url(http://lorempixel.com/939/528/)">
<div class="seo">
Have a meaningful description of the video here
</div>
</div>
CSS:
.ytvideo {
background-position: center;
background-size: contain;
background-repeat: no-repeat;
cursor: pointer;
}
.ytvideo iframe {
border-style: none;
height: 100%;
width: 100%;
}
.ytvideo .seo {
display: none;
}
jQuery:
$('.ytvideo[data-video]').one('click', function() {
$(this).html('<iframe allowfullscreen src="//www.youtube.com/embed/'+$(this).data("video")+'?autoplay=1"></iframe>');
});
If you want to support browsers with no script support, you'd have to add a "noscript" element in the .ytvideo div that already contains the iframe.
