The

JS code is as follows:

Load the JS statement after text read begins ============================================================= function fadeimg (obj,speed, Interval) {//parent container, fade fade in speed, toggle Interval $ ("." +obj). each (function () {var $box = $ (this), $imgUl = $box. Children (". Imglist"), $imgLi = $imgUl. Child ren ("Li"), $btnUl = $box. Children (". Btnlist"), $btnLi = $btnUl. Children ("Li"), $btnPreNex = $box. C
      Hildren (". Pre-nex"), n = $imgLi. length, k = 0, Player = setinterval (function () {fade ()},interval);             $imgLi. EQ (0). FadeIn (speed);
        First fade function fade () {//Fade in event K + 1;
        if (k >= n) {k = 0;
        $btnLi. Removeclass (' cur '). EQ (k). addclass (' cur ');  
      $imgLi. fadeout (Speed). EQ (k). FadeIn (speed);
      };
        $btnLi. Click (function () {//small dot Click event var index = $btnLi. index (this);
        $ (this). addclass (' cur '). Siblings (' Li '). Removeclass (' cur '); $imgLi. fadeout (speed). eq(index). FadeIn (speed);
      K = index;     
      }); $btnPreNex. Click (function () {//Left button click event if (! $imgLi. Is (": Animated")) {if ($)
            . Hasclass (' next ')) {k + 1;
            if (k >= n) {k = 0;
            } else{k + =-1;
            if (k < 0) {k = n-1;
          } $btnLi. removeclass (' cur '). EQ (k). addclass (' cur ');
        $imgLi. fadeout (Speed). EQ (k). FadeIn (speed);   
      }  
      });
          $box. Hover (///mouse move event (not toggle to be compatible with 1.9+ JQ library) function () {clearinterval (Player);
        $btnPreNex. addclass (' show ');
          The function () {Player = SetInterval (function () {fade ()},interval);
        $btnPreNex. Removeclass (' show ');        
    }
      );
  });
  } $ (function () {//Read Carousel event fadeimg ("Bannercon", 1000,3000);   });

JQ Library with 1.7+ is no problem, I hope to learn some help, feel good students on the quiet point of praise Bar.
