<div class="btn_left button"> < </div>

关键是下面
<script src="jquery-3.1.1.js"></script>
<script>
var $img_index=$(".img li").length;
for(var i=0;i<$img_index;i++){
$(".btn").append("<li></li>");
}
实现鼠标点击
$(".btn li").eq(0).css("background-color","red");
$(".btn li").mouseover(function () {
var btn_index=$(this).index();
$(this).css("background-color","red").siblings().css("background-color","white");
$(".img li").eq(btn_index).stop().fadeIn(1000).siblings().stop().fadeOut(1000);
});
var clock=setInterval(turn,1500);
var i=0;
function turn() {
if(i==$img_index-1){
i=-1;
}
i++;
$(".img li").eq(i).stop().fadeIn(1000).siblings().stop().fadeOut(1000);
$(".btn li").eq(i).css("background-color","red").siblings().css("background-color","white");
}
$(".outor").hover(function () {
clearInterval(clock);
},function () {
clock=setInterval(turn,1500);
})
$(".btn_left").click(function () {
i--;
console.log(i);
$(".img li").eq(i).stop().fadeIn(1000).siblings().stop().fadeOut(1000);
$(".btn li").eq(i).css("background-color","red").siblings().css("background-color","white");
if(i==0){
i=$img_index;
}
});
$(".btn_right").click(function () {
if(i==$img_index-1){
i=-1;
}
i++;
$(".img li").eq(i).stop().fadeIn(1000).siblings().stop().fadeOut(1000);
$(".btn li").eq(i).css("background-color","red").siblings().css("background-color","white");
