JQuery split screen indicator picture rotation effect example_jquery

The example in this article describes how to implement the JQuery split-screen indicator image rotation effect. Share it with everyone for your reference. The specific analysis is as follows:

Today when Web Apps are very popular, split-screen indicators are widely used, from Android to Tencent’s Web OS and so on. The split-screen indicator gives people a good user experience. Let’s implement a split-screen indicator to achieve a simple rotation effect of pictures. It’s just a starting point~

The code is as follows:

 <script type="text/javascript">
   var curr = 0, next = 0, count = 0;
   $(document).ready(function () {
     // 记录图片的数量 
     count = $('#img_list a').size();
     t = setInterval('imgPlay()', 3000);
     // 鼠标移动到图片或导航上停止播放，移开后恢复播放 
     $('#imgs li, #img_list a').hover(function () {
       clearInterval(t);
     }, function () {
       t = setInterval('imgPlay()', 3000);
     });
     //点击导航播放到相应的图片 
     $('#img_list a').click(function () {
       // index()函数返回当前导航的下标
       var index = $('#img_list a').index(this);
       if (curr != index) {
         play(index);
         curr = index;
       };
       return false;
     });
   });
   // 播放图片的函数
   var imgPlay = function () {
     next = curr + 1;
     // 若当前图片播放到最后一张，这设置下一张要播放的图片为第一张图片的下标
     if (curr == count - 1) next = 0;
     play(next);
     curr++;
     // 在当前图片的下标加1后，若值大于最后一张图片的下标，则设置下一轮其实播放的图片下标为第一张图片的下标，而next永远比curr大1
     if (curr > count - 1) { curr = 0; next = curr + 1; }
   };
   // 控制播放效果的函数
   var play = function (next) {
     // 当前的图片滑到左边-500px，完成后返回到右边490px
     // 下一张图片滑到0px处，完成后导航的焦点切换到下一个点上
     $('#imgs li').eq(curr).css({ 'opacity': '0.5' }).animate({ 'left': '-530px', 'opacity': '1' }, 'slow', function () {
       $(this).css({ 'left': '520px' });
     }).end()
.eq(next).animate({ 'left': '0px', 'opacity': '1' }, 'slow', function () {
  $('#img_list a').siblings('a').removeClass('active').end().eq(next).addClass('active');
});
   };
 </script>
