html - How do I get the information from a meta tag with JavaScript?

Question

The information I need is in a meta tag. How can I access the "content" data of the meta tag when property="video"?

HTML:

<meta property="video" content="http://video.com/video33353.mp4" />

Answer 1

The other answers should probably do the trick, but this one is simpler and does not require jQuery:

document.head.querySelector("[property~=video][content]").content;

The original question used an RDFa tag with a property="" attribute. For the normal HTML <meta name="" …> tags you could use something like:

document.querySelector('meta[name="description"]').content
