Javascript – Play Youtube iframe full screen

htmliframejavascriptjqueryyoutube-api

I've got a page with a embedded Youtube video in a iframe.
I want to set the video to full screen whenever someone plays the video.
I've tried many things but can't seem to get it working.

My code:

<div class="video-wrapper">
    <div class="video">
        <iframe id="home-video" allowfullscreen="allowfullscreen"     mozallowfullscreen="mozallowfullscreen"
                                        msallowfullscreen="msallowfullscreen" oallowfullscreen="oallowfullscreen"
                                        webkitallowfullscreen="webkitallowfullscreen" frameborder="0"
                                        src="https://www.youtube.com/watch_popup?v=dQw4w9WgXcQ">
        </iframe>
    </div>
</div>

I also tried to accomplish this with the Youtube Api, but without success.

 <script src="https://www.youtube.com/iframe_api"></script>

Anyone?

I would try the fullScreen API for HTML5:

function fullScreen() {

    var e = document.getElementById("video-wrapper");
    if (e.requestFullscreen) {
        e.requestFullscreen();
    } else if (e.webkitRequestFullscreen) {
        e.webkitRequestFullscreen();
    } else if (e.mozRequestFullScreen) {
        e.mozRequestFullScreen();
    } else if (e.msRequestFullscreen) {
        e.msRequestFullscreen();
    }
}

function YTStateChange(event) {
    switch(event.data) {
        case -1:
            fullScreen();
        break;
        case 1:
            // some code
        break;
        case 2:
            // some code 
        break;
        default:
        break;
    }
}

$(document).ready(function () {
    var player = new YT.Player( 'video-wrapper', {
        events: { 'onStateChange': YTStateChange }
    });
});

2015 update: the flexbox approach

There are two other answers briefly mentioning flexbox; however, that was more than two years ago, and they don't provide any examples. The specification for flexbox has definitely settled now.

Note: Though CSS Flexible Boxes Layout specification is at the Candidate Recommendation stage, not all browsers have implemented it. WebKit implementation must be prefixed with -webkit-; Internet Explorer implements an old version of the spec, prefixed with -ms-; Opera 12.10 implements the latest version of the spec, unprefixed. See the compatibility table on each property for an up-to-date compatibility status.

(taken from https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes)

All major browsers and IE11+ support Flexbox. For IE 10 or older, you can use the FlexieJS shim.

To check current support you can also see here: http://caniuse.com/#feat=flexbox

Working example

With flexbox you can easily switch between any of your rows or columns either having fixed dimensions, content-sized dimensions or remaining-space dimensions. In my example I have set the header to snap to its content (as per the OPs question), I've added a footer to show how to add a fixed-height region and then set the content area to fill up the remaining space.

html,
body {
  height: 100%;
  margin: 0;
}

.box {
  display: flex;
  flex-flow: column;
  height: 100%;
}

.box .row {
  border: 1px dotted grey;
}

.box .row.header {
  flex: 0 1 auto;
  /* The above is shorthand for:
  flex-grow: 0,
  flex-shrink: 1,
  flex-basis: auto
  */
}

.box .row.content {
  flex: 1 1 auto;
}

.box .row.footer {
  flex: 0 1 40px;
}

<!-- Obviously, you could use HTML5 tags like `header`, `footer` and `section` -->

<div class="box">
  <div class="row header">
    <p><b>header</b>
      <br />
      <br />(sized to content)</p>
  </div>
  <div class="row content">
    <p>
      <b>content</b>
      (fills remaining space)
    </p>
  </div>
  <div class="row footer">
    <p><b>footer</b> (fixed height)</p>
  </div>
</div>

In the CSS above, the flex property shorthands the flex-grow, flex-shrink, and flex-basis properties to establish the flexibility of the flex items. Mozilla has a good introduction to the flexible boxes model.
