Embedding videos using YouTube's iFrame embed code sucks. Just how much does it suck you might ask? Well, each YouTube video you embed forces the user to download roughly 400K of data before they even click play.
Use jquery.nonSuckyYouTubeEmbed.js for a huge performance boost whenever your site calls for embedded YouTube videos. This plugin takes the YouTube video ID as the ID attribute of the element it is called on and fetches the thumbnail image and displays that first (with a play button laid over). Only when the thumbnail is clicked does it fetch the heavy iFrame. Optimized for responsive design environments!
Check out jquery.nonSuckyYouTubeEmbed live and in action here...
Create an element (or elements) with the ID attribute set to the video's YouTube ID. For example if the video's URL is youtube.com/watch?v=HoQN7K6HdRw then the ID is HoQN7K6HdRw.
<div id="CqZgd6-xQl8" class="nonSuckyYouTubeEmbed"></div>
Then call the plugin on that (or those) element(s).
The following attributes can (and should) be set on each element that jquery.nonSuckyYouTubeEmbed() is called on. These attributes are set on the element rather than as options when calling the plugin so the plugin can easily be called on a group of elements where these attributes are different.
data-width: The width of the iFrame player. While jquery.nonSuckyYouTubeEmbed will make the iFrame responsive / fluid, this value, combined with data-height is used to calculate the iFrame's aspect ratio. This parameter is optional but recommended to avoid black bars on the sides of the video.
data-height: The height of the iFrame player. While jquery.nonSuckyYouTubeEmbed will make the iFrame responsive / fluid, this value, combined with data-width is used to calculate the iFrame's aspect ratio. This parameter is optional but recommended to avoid black bars on the sides of the video.
data-alt: The alt text for the thumbnail image. Optional, but recommended.
The following options are available when calling jquery.nonSuckyYouTubeEmbed...
defaultWidth: This will be used for the iFrame's width if the
data-width attribute is not supplied.
defaultHeight: This will be used for the iFrame's height if the
data-height attribute is not supplied.
playBtnSrc: Source of play button that is laid over thumbnail. Default uses data URI
playBtnStyle: If you are changing the play button source you will need to change the style as well to ensure that it is centered over the thumbnail. Here's a code snippet on how to do that. Parameter takes a string of CSS that will be used for the inline style attribute on the play button element.
thumbStyle: A string of CSS that will be used for the inline style attribute on the thumbnail image. Uses
width: 100%; height: auto; display: inline; cursor: pointer by default to make images responsive. If you are changing this keep in mind that
display: inline; is important for to keep the play button laid on top of the thumbnail.
Tested in the following browsers...
On Mac OS X 10.9
- Chrome 31.0.1650.57
- Firefox 25.0.1
- Safari 7.0
- Opera 12.16
- IE 7+ (With IE 7 you need to change play button source to non-dataURI)
- iOS 4+
- Android 4.0 (Motorola Razr)
- Android 2.2 (LG Optimus 2.2)
- The videos are fetched with
autoplay=1in the URL, but autoplay generally does not work on mobile, so users will have to click play one more time :/. See this Stack Overflow thread
