jQuery touchmove not registering in chrome emulator

问题

There's been similar questions on how to fire scroll events (mid-scroll) on mobile/tablet. I've used the code provided below but I've yet to get this to work in chrome emulator.

$('body').on({
   'touchmove': function(e) {
       console.log($(this).scrollTop()); // Replace this with your code.
    }
});

touchstart will log when I scroll with the touch sensor but not touchmove. What am I missing?

回答1:

Did you enable the "emulate touch screen"?

check this link in "sensors" http://www.sitepoint.com/use-mobile-emulation-mode-chrome/

Try this code

<script type="text/javascript">
 $(document).bind('touchmove', function(e) {
   console.log($(this).scrollTop()); 
 });
</script>

I use bind and originalEvent, which works on real mobile device:

    $("html").bind("touchmove", function(e)
    {
        e.preventDefault();
        var touch = e.originalEvent.touches[0] || e.originalEvent.changedTouches[0];
        var x = touch.pageX, y =touch.pageY;
