When making HTML5 video tags, we have the download function itself, but in the video area, right-click to "save video as",
to download the video, in order to block "save video as", you can use js Add the following code:
$('#myVideo ').bind('contextmenu',function() { return false; });
where myVideo is the id of the video tag, so that the right-click function of the video tag area can be blocked,
But it cannot achieve real shielding (you know...).
