Jquery Detect First Mouse Movement

I'm looking to detect the first occurrence of a mouse movement so I can target human visitors with jquery affects. Any leads on how I might accomplish this. I'd also like to do this without t开发者_运维技巧argeting class names or object ids... so a blanked target on the tag should do. Any advice?

$('body').one('mousemove', function() { .... } );

This will look for mouse movement anywhere, but will only do it once.

Note: This isn't exactly a reliable method, smartphones don't have mice. And a non-human program can still move the mouse.

But it does answer your question.

Mouse events bubble to the document unless blocked. You can generally see them with a mousemove handler on the document:

document.onmousemove = function() {console.log("mousemove");}

or in jQuery:

$(document).mousemove(function() {
    // put your code here
});

If you only want to see a few initial mouse movements, you can remove the event handler at the desired time or just ignore future events once you've detected a human.

Why would you bother not running animations when it's not a human? Does it cost you something? Animation is a client-side thing, right? Chances are, if it's not a human (like a bot of some type), it isn't running javascript anyway.

Not sure if I understand your purpose corretly, but how about something like this:

var detectMouseMovement = function() {
    $(document).unbind('mousemove', detectMouseMovement);

    // do whatever you need to do..
};

$(document).bind('mousemove', detectMouseMovement);
