javascript - Implement autoplay, pause on hover, keyboard control on slideshow -


i trying implement this sideshow on project, , want add features :

  • auto-play
  • pause on hover
  • multiple instance of slider
  • go next slide keyboard arrow keys

what have tried ?

i have added code

        var autoscroll = window.setinterval(function(){ navigate( 'next' )}, 5000);      component.onmouseover = function(e){         autoscroll = clearinterval(autoscroll);         console.log('onmouseover');     };     component.onmouseout = function(e) {             clearinterval(autoscroll);             var autoscroll = setinterval(function() {navigate( 'next' )}, 5000);             console.log('onmouseout');     };

live demo: http://jsfiddle.net/m2cwf/1/

what problem ?

  • the autoplay works fine until manually use control arrow, see interval change in case, maybe need add condition if( isanimating ) return false;

  • the pause on hover not seems work, , console log see event fired several times in 1 single hover !

  • if have multiple instance of slider first 1 works

  • the keyboard keys pass next slide

    thank you help.

the problem how handling mouseover , mouseout redefining global autoscroll variable instead of changing value in mouseout event.

changing , relatively simple keydown event code fixed slideshow want (i think).

the changes made mouseover/mouseout code:

var autoscroll = window.setinterval(function(){ navigate( 'next' )}, 5000);          component.onmouseover = function(e){             autoscroll = clearinterval(autoscroll);             console.log('onmouseover');         };         component.onmouseout = function(e) {                 clearinterval(autoscroll);                 autoscroll = setinterval(function() {navigate( 'next' )}, 5000);                 console.log('onmouseout');         };

and here's code arrow key events:

document.onkeydown = function(event) {     event = event || window.event;     switch (event.keycode || event.which) {         case 37:             clearinterval(autoscroll);             navigate( 'prev' );             autoscroll = setinterval(function() {navigate( 'next' )}, 5000);             break;         case 39:             clearinterval(autoscroll);             navigate( 'next' );             autoscroll = setinterval(function() {navigate( 'next' )}, 5000);             break;     } };

here's came with: http://jsfiddle.net/m2cwf/2/

update

here's version supports multiple slideshows per page. eliminated left , right arrow actions though because i'm not sure how want handle navigating multiple slideshows on 1 page...

it shouldn't hard modify code make happen though.
