一段关于焦点图的 JS 代码，请各位师傅指点
这段代码只要点击下一个或者上一个之后，就不会自动播放了，网上下来学习的，水平有限，修改不了，请各位师傅帮忙指点下，在此谢谢各位了！只有30分了，改对了全给了

程序代码： $(window).load(function() {
$('.flexslider').flexslider()
});
$(document).ready(function() {
$('.flexslider').hover(function() {
$('.flex-direction-nav li a.prev').css('display', 'block');
$('.flex-direction-nav li a.next').css('display', 'block')
},
function() {
$('.flex-direction-nav li a.prev').css('display', 'none');
$('.flex-direction-nav li a.next').css('display', 'none')
})
});
