HTML
<video id="vdisk" controls poster="<?php echo $vposter ?>">
<source src="" type="video/mp4">
</video>
jQuery
$("#vdisk source").attr("src", a); // a is a variable
console.log(a); //vdisk/01.mp4 - that's ok
When clicking on a "play" button nothing happens. There is no video in vdisk
. The console is empty.
