如何在滑块悬停时暂停

Question

Js

var $slider = $('.slider'); 
var $slide = 'li'; 
var $transition_time = 1000;
var $time_between_slides = 4000; 
function slides(){
  return $slider.find($slide);

}

slides().fadeOut();
slides().first().addClass('active');
slides().first().fadeIn($transition_time);
$interval = setInterval(
    function(){
      var $i = $slider.find($slide + '.active').index();

      slides().eq($i).removeClass('active');
      slides().eq($i).fadeOut($transition_time);

      if (slides().length == $i + 1) $i = -1; // loop to start

      slides().eq($i + 1).fadeIn($transition_time);
      slides().eq($i + 1).addClass('active');
    }
    , $transition_time +  $time_between_slides 
);

CSS

.slider { margin: 10px 0; width: 1024px; height: 500px; position: relative; overflow: hidden; } 
.slider li { display: none; position: absolute; top: 0; left: 0; }

在图像上使用 mouseover 和 mouseout 事件来实现此目的。

var $slider = $('.slider'); 
var $slide = 'li'; 
var $transition_time = 1000; 
var $time_between_slides = 4000; 
function slides(){ 
  return $slider.find($slide);
}

slides().fadeOut();
slides().first().addClass('active');
slides().first().fadeIn($transition_time);

$function = function(){
      var $i = $slider.find($slide + '.active').index();

      slides().eq($i).removeClass('active');
      slides().eq($i).fadeOut($transition_time);

      if (slides().length == $i + 1) $i = -1; // loop to start

      slides().eq($i + 1).fadeIn($transition_time);
      slides().eq($i + 1).addClass('active');
    }

$interval = setInterval($function, $transition_time +  $time_between_slides );

$("img").on("mouseover",function(){
 clearInterval($interval);
});

$("img").on("mouseout",function(){
  $interval = setInterval($function, $transition_time +  $time_between_slides );
});

.slider { margin: 10px 0; width: 1024px; height: 500px; position: relative; overflow: hidden; } .slider li { display: none; position: absolute; top: 0; left: 0; }
