        <ul class="btn">
        </ul>
        <div class="btn_left button"> < </div>
        <div class="btn_right button"> > </div>

</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"); }); </script> </body> </html>
