本文实例讲述了jQuery实现的左右移动焦点图效果。分享给大家供大家参考，具体如下：

jquery 部分：

$(function () { var _speed = 1000; var _len = 0; var _size = 150; var _direction = 'left'; function mar(){ if(_direction == 'left'){ if(_len >= 450){ _direction = 'right'; }else{ $(".flow ul").animate({"margin-left":"-=" + _size + "px"}); _len += _size; } }else{ if(_len <= 0){ _direction = 'left'; }else{ $(".flow ul").animate({"margin-left":"+=" + _size + "px"}); _len -= _size; } } } var _go = setInterval(mar,_speed); $("#pic_left").click(function (){ _direction = 'left'; }); $("#pic_right").click(function (){ _direction = 'right'; }); $(".flow li").mouseover(function (){ clearInterval(_go); }).mouseout(function (){ _go = setInterval(mar,_speed); }); });

html 部分

<div> <A id="pic_left">left</A> <DIV id="ISL_Cont_1"> <DIV> <div> <div> <ul > <li><img src="__PUBLIC__/images/demo/01.jpg" mce_src="__PUBLIC__/images/demo/01.jpg" width="150px" height="60px"></li> <li><img src="__PUBLIC__/images/demo/02.jpg" mce_src="__PUBLIC__/images/demo/02.jpg" width="150px" height="60px"></li> <li><img src="__PUBLIC__/images/demo/03.jpg" mce_src="__PUBLIC__/images/demo/03.jpg" width="150px" height="60px"></li> <li><img src="__PUBLIC__/images/demo/04.jpg" mce_src="__PUBLIC__/images/demo/04.jpg" width="150px" height="60px"></li> </ul> </div> </div> </DIV> </DIV> <A id="pic_right">right</A> </div>

希望本文所述对大家jQuery程序设计有所帮助。
