I am using Angular.JS with tizen to create a smart tv app. I want to get a list of subtitles to show on my video app but I keep getting this error: "Error: The caph-list's container and template view should have their own size such as width and height."
On my main html I have a "settings" directive here:
<settings></settings>
that uses settings.html to display a caph-list here:
<caph-list container-class="container" wrapper-class="setting-wrapper" items="item in subtitles"> <div class="item" focusable>{{item}}</div> </caph-list>
I've tried various setups with the container and wrappers such as this within my settings.html:
<div class="container">
<div class="wrapper">
<caph-list container-class="container" wrapper-class="setting-wrapper" items="item in
subtitles">
<div class="item" focusable>{{item}}</div>
</caph-list>
</div>
</div>
But I still am getting the same error.
Here is the CSS being used on the container and wrapper classes:
.container {
width: 800px;
height: 100px;
background-color: red;
}
.setting-wrapper {
width: 400px;
height: 100px;
left: 50px;
background-color: green;
}
.item {
width: 20px;
height: 20px;
background-color: blue;
margin: 10px;
}
Here is the subtitles array at the start:
$scope.subtitles = ["1","2","3"]
This array will change to an array of objects containing subtitle information when a video is chosen.
Your container has 0 px width, probably. Try setting an absolute value instead of percentage, i.e, 800 px instead of 60%), and make sure that the parent element has a width and height (not 0.)

So I'm making myself a website and I have hit a brick wall. I would like to know if it is possible to use JavaScript to get the height of a floated object, and set the height of another object with this floated object's height. Basically the second object would ideally be the same height as the floated object, which just so happens to be a video with an id attribute. I would like to know if this is even possible? And if so, how to do it?
So far this is the code I have:
Two examples of the HTML blocks:
<div class="vidFloat" id="vidFloat">
<div class="floatL"><video id="vid" src="../vid/videoname.mp4" type="video/mp4" controls></video></div>
<h2>this video...</h2><p>hi there</p>
</div>
<div class="vidFloat" id="vidFloat">
<div class="floatR"><video id="vid" src="../vid/videoname.mp4" type="video/mp4" controls></video></div>
<h2>this video...</h2><p>hi there</p>
</div>
JavaScript:
var vidRef = document.getElementById('vid');
var mHeight = vidHeight.offsetHeight;
var contentHeight = document.getElementById('vidFloat').style.height;
if (contentHeight!=mHeight){
contentHeight.style.maxHeight = mHeight;
}
CSS:
.vidFloat{
margin-bottom: 15px;
display: none;
overflow: hidden;
width: 100%;
background-color: rgba(255,255,255,0.2);
}
.floatL {
width: 50%;
float: left;
}
.floatL video{
width: 100%;
}
.floatR {
width: 50%;
float: right;
}
.floatR video{
width: 100%;
}
/*
The following are IDs used in javascript, and then media queries
*/
#vidFloat{}
#vid{}
So I've started playing around with bigvideo.js (which is built on top of video.js) and it works fine for the basic usage of having a fixed background video over the whole screen. I have also managed to show it inside of a div.
My problem though, is that I can't seem to stack other DIVs with other content over or under the bigvideo.js container div, and I can't seem to figure out how to solve this.
My HTML:
<div style="float: left; width: 100%; height: 300px;">
<h1>hi there</h1>
</div>
<div style="float: left; width: 100%; height: 500px;" id="intro-video-container">
</div>
JS firing up bigvideo:
$(function() {
var BV = new $.BigVideo({container: $('#intro-video-container'),useFlashForFirefox:false});
BV.init();
BV.show('intro.mp4',{ambient:true});
});
So the video container div ALWAYS gets stuck up to the left top of the body, no matter if I try to force it down with margin-top, or place divs before it, etc.
Any ideas?
Update, here is an illustration of what I kind of what to achieve:
Try to use container div (so called wrapping) in your page where you will place the desired content (as on the plugin's example page):
CSS
.box {
background:#444; background:rgba(0,0,0,.6);
padding:20px;
border-radius:5px;
margin-bottom:20px;
}
.main {
position:relative;
margin:50px 50px 440px 220px;
min-width:300px;
-webkit-transition-duration:0.6s;-moz-transition-duration:0.6s;-ms-transition-duration:0.6s;-o-transition-duration:0.6s;transition-duration:0.6s;
}
.dimmed {
color: #ccc;
}
#big-video-wrap {
height: 100%;
left: 0;
overflow: hidden;
position: fixed;
top: 0;
width: 100%;
}
HTML
<div id="big-video-wrap"></div>
<div class="main">
<div id="overview" class="box">
<h1>BigVideo<span class="dimmed"><small>.</small>js</span></h1>
<h2>Simple Ambient Video Example</h2>
</div>
</div>
JavaScript
$(function() {
var BV = new $.BigVideo({container: $('#big-video-wrap'),useFlashForFirefox:false});
BV.init();
BV.show('intro.mp4',{ambient:true});
});
EDIT:
Now, it is more clear what you are trying to achieve, the simplest solution is to include an iframe on place of the div, which points to your full-screen video page.
I.e. create page video.html with all initializations and plug-in includes, then use it as source of your iframe on main page. Your iframe can be styled to match the desired dimensions (for example 100% width and 300px height).
I'm looking for the best way to do a progress bar (in my case it's a life bar for a game) in an html5 canvas.
I don't know if it's better to use javascript and dom element, or draw this bar directly in the canvas.
I need an update function, for example myBar.updateValue(40), and I need to show the new bar without refresh all the page or all the canvas, of course.
Do you know something like that? An existing script? Thanks!
It’s very easy in HTML/CSS:
<style>
#progress-holder{width:400px;height:20px;background:grey}
#progress{width:0;height:100%;background:black}
</style>
<div id="progress-holder">
<div id="progress"></div>
</div>
<script>
var progress = document.getElementById('progress');
function updateValue(perc) {
progress.style.width = perc+'%';
}
updateValue(40);
</script>

And animating with CSS: http://jsbin.com/EGAzAZEK/3/edit
HTML:
<div class='progress'>
<div class='progress-bar' data-width='//Enter a percent value here'>
<div class='progress-bar-text'>

</div>
</div>
CSS:
html, body {
margin: 0;
padding: 15px;
width: 100%;
height: 100%;
position: relative;
color: #fff;
}
.progress {
position: relative;
width: 100%;
height: 30px;
}
.progress-bar {
margin-bottom: 5px;
width: 0%;
height: 30px;
position: relative;
background-color: rgb(66, 139, 202);

.progress-bar-text {
position: absolute;
top: 0px;
width: 100%;
text-align: center;
/*
Do not change the values below,
unless you want your text to display away from the bar itself. */
line-height: 30px;
vertical-align: middle;
}
jQuery:
$('.progress-bar').each(function (){
var datawidth = $(this).attr('data-width');
$(this).find("span.data-percent").html(datawidth + "%");
$(this).animate({
width: datawidth + "%"
}, 800);
});
Link to JSFiddle
The HTML data-width attribute is used to track the percent the bar should be set to. Change it to your liking.
The jQuery script works with ALL progress bars on your page (See the JSFiddle, so you don't have to copy and paste the same jQuery for every new progress bar.
(Just be sure to keep the structure of the HTML, or change it to your liking).
The div "progress" is just an expander, it can be named whatever your want - without you having to change the jQuery.
EDIT:
If you can use Javascript & HTML, don't use a canvas. Canvas (imho) are good for only 1 thing: Seat bookings for concerts, theaters and alike.
I'm trying to position a fixed element WITHIN a div (not the whole page) in my website.
I want the navigation (deadspin, gawer, awl, other) to be fixed within the writing section so that even when user scrolls, the nav is still there. But currently it's fixed for the whole page.
As you can see on my test page, the navigation is fixed the way I want it to be.
I tried messing around with position:relative/position:fixed for the #small-box-links but that doesn't help.
.home_writing {
display: block;
position: relative;
background: rgba(50, 50, 50, 0);
height: 1000px;
text-align: left;
}
#small-box-container {
border: 1px solid black;
background: rgba(10, 200, 10, 0);
width: 980px;
height: 800px;
overflow: auto;
}
#small-box-links {
position: relative;
margin-left: 700px;
height: 25px;
margin-top: 10px;
}
<div id="small-box-container">
<div id="small-box-links">
deadspin |
gawker |
the awl |
other
</div>
<div style='overflow:hidden; width:980px;'>
<div style='overflow:scroll; width:988px'>
<div id="small-box1" class="small-box">
<h2>deadspin</h2>
<h3>How Pat Summitt Ruined The Best Thing About Women's Basketball</h3>
<!-- etc. for other boxes -->
I found this related question and yet when I try top / left, etc., the element is still fixed to the page, not writing div. (I tried making the parent element, .home_writing, relative but this doesn't fix my issue.)
(On another note, I can't figure out why my Playfair in the paragraphs doesn't look like the sidebar navigation. It's styled the same way).
position:fixed always uses the viewport as the frame of reference, so you can’t use that here.
But the solution is rather simple - use position:absolute instead to position the navigation inside a container element that has position:relative (and a fixed height), and then have the content as a sibling inside that container as well, with fixed height and overflow:auto for that element:
<div style="position:relative; height:800px;">
<div style="position:absolute; top:0; …"> [link link link] </div>
<div style="height:800px; overflow:auto;">
Lorem ipsum, dolor sit …
</div>
</div>
I have a layout where images "float" within a certain area. The layout looks like this:
The source like this:
<div class="free_tile">
<a class="img_container canonical" href="/photos/10">
<img class="canonical" src="http://s3.amazonaws.com/t4e-development/photos/1/10/andrew_burleson_10_tile.jpg?1303238025" alt="Andrew_burleson_10_tile">
<!-- EDIT: I am aware that I can put the badge here. See the edit notes and image below. -->
</a>
<div class="location">Houston</div>
<div class="taxonomy"> T6 | Conduit | Infrastructure </div>
</div>
The CSS looks like this (in SCSS):
div.free_tile { width: 176px; height: 206px; float: left; margin: 0 20px 20px 0; position: relative;
&.last { margin: 0 0 20px 0; }
a.img_container { display: block; width: 176px; height: 158px; text-align: center; line-height: 156px; margin-bottom: 10px; }
img { margin: 0; border: 1px solid $dark3; display: inline-block; vertical-align: middle; #include boxShadow;
&.canonical { border: 1px solid $transect; }
}
.location, .taxonomy { width: 176px; }
.location { font-weight: 700; }
.taxonomy { line-height: 10px; font-size: 10px; text-transform: uppercase; height: 20px; overflow: hidden; }
}
div.transect_badge { height: 20px; width: 20px; background: url('/images/transect-badge.png'); }
So, basically the images are sitting vertically-aligned middle and text-aligned center, and they have a maximum width of 176 and max height of 158, but they're cropped to maintain the original aspect ratio so the actual top corner of each image falls differently depending on which image it is.
I have a badge that I'd like to put in the top corner of certain images (when the image is "canonical"). You see the style for this above (div.transect_badge).
The problem, of course, is I don't know where the top corner of the image will be so I can't hardcode the position via CSS.
I assume that I'll need to do this via jQuery or something. So, I started with a jQuery method to automatically append the badge div to any canonical images. That works fine, but I can't figure out how to position it over the top left corner.
How can this be done? (ideally using just HTML and CSS, but realistically using JS/jQuery)
--EDIT--
Here's the problem: The image is floating inside a container, so the corner of the image might fall anywhere inside the outer limits of the container. Here's an example of what happens if I try to use position:absolute; top:0; left:0 inside the same container the image is bound by:
It took some tryouts, but here it is: the size independent image badge positioner.
HTML:
<div class="tile">
<span class="photo">
<img src="/photos/10.jpg" alt="10" /><ins></ins>
</span>
<p class="location">Houston</p>
<p class="taxonomy">T6 | Conduit | Infrastructure</p>
</div>
CSS:
.tile {
float: left;
width: 176px;
height: 206px;
margin: 0 20px 20px 0;
}
.photo {
display: block;
width: 176px;
height: 158px;
text-align: center;
line-height: 158px;
margin-bottom: 10px;
}
a {
display: inline-block;
position: relative;
line-height: 0;
}
img {
border: none;
vertical-align: middle;
}
ins {
background: url('/images/badge.png') no-repeat 0 0;
position: absolute;
left: 0;
top: 0;
width: 20px;
height: 20px;
}
Example:
In previous less successful attempts (see edit history), the problem was getting the image vertically centered ánd to get its parent the same size (in order to position the badge in the top-left of that parent). As inline element that parent doesn't care about the height of its contents and thus remains to small, but as block element it stretches to hís parent's size and thus got to high, see demonstration fiddle. The trick seems to be to give that parent a very small line-height (e.g. 0) and display it as an inline-block. That way the parent will grow according to its childs.
Tested in Opera 11, Chrome 11, IE8, IE9, FF4 and Safari 5 with all DTD's. IE7 fails, but a center-top alignment of the photo with badge at the right position isn't that bad at all. Works also for IE7 now because I deleted the spaces in the markup within the a tag. Haha, how weird!
EDIT3: This solution is very similar to my original solution. I didn't really look at your code much so I should have noticed this earlier. Your a tag is already wrapping each image so you can just add the badge in there and position it absolute. The a tag doesn't need width/height. Also you must add the badge image at the beginning of your a tag.
Demo: http://jsfiddle.net/wdm954/czxj2/1/
div.free_tile {
width: 176px;
height: 206px;
float: left;
}
a.img_container {
display: block;
margin-bottom: 10px;
}
span.transect_badge {
display:block;
position: absolute;
height: 20px;
width: 20px;
background-image: url('/images/transect-badge.png');
}
HTML...
<a class="img_container canonical" href="/photos/10">
<span class="transect_badge"></span>
<img class="canonical" src="path/to/img" />
</a>
Other solutions...
In my code I'm using SPAN tags so simulate images, but it's the same idea. The badge image, when positioned absolute, will create the desired effect.
Demo: http://jsfiddle.net/wdm954/62faE/
EDIT: In the case that you need jQuery to position. This should work (where .box is your container and .corner is the badge image)...
$('.box').each(function() {
$(this).find('.corner')
.css('margin-top', ( $(this).width() - $(this).find('.img').width() ) / 2);
$(this).find('.corner')
.css('margin-left', ( $(this).height() - $(this).find('.img').height() ) / 2);
});
EDIT2: Another solution would be to wrap each image with a new container. You would have to move the code that you use to center each image to the class of the new wrapping container.
Demo: http://jsfiddle.net/wdm954/62faE/1/
$('.img').wrap('<span class="imgwrap" />');
$('.imgwrap').prepend('<span class="badge" />');
Technically you can just add something like this to your HTML though without using jQuery to insert it.
Use an element other than <div>, e.g. <span> and put it inside your <a> element after the <img> element. Then, give the <a> element position:relative; and the <span> gets position:absolute; top:0px; left:0px;. That is, if you don't mind the badge also being part of the same link - but it's the easiest way. Also, the reason for using <span> is to keep your HTML4 valid, <div> would still be HTML5 valid, however.
I did find one solution using jQuery. I don't prefer this because it noticably impacts page loading, but it is acceptable if nothing else will work. I'm more interested in NGLN's idea which seems promising but I haven't entirely figured out yet. However, since this thread has picked up a lot of traffic I thought I'd post one solution that I came up with for future readers to consider:
Given this markup:
<div class="free_tile">
<a class="img_container canonical" href="/photos/10">
<img class="canonical" src="http://s3.amazonaws.com/t4e-development/photos/1/10/andrew_burleson_10_tile.jpg?1303238025" alt="Andrew_burleson_10_tile">
<span class="transect-badge"></span>
</a>
<div class="location">Houston</div>
<div class="taxonomy"> T6 | Conduit | Infrastructure </div>
</div>
Same CSS as in question except:
span.transect-badge { display: block; height: 20px; width: 20px; position: absolute; background: url('/images/transect-badge.png'); }
Then this jQuery solves the problem:
$(function() {
$('img.canonical').load( function() {
var position = $(this).position();
$(this).next().css({ 'top': position.top+1, 'left': position.left+1 });
});
});
Like I said, though, this incurs noticeable run-time on the client end, so I'd prefer to use a non JS solution if I can. I'll continue to leave this question open while I test out and give feedback on the other solutions offered, with hopes of finding one of them workable without JS.
