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 class="salebox">
<A class="left" id="pic_left">left</A>
<DIV class="pcont" id="ISL_Cont_1">
<DIV class="ScrCont">
<div class="flowbox" style="width:150px; height:60px; overflow:hidden;float:left;">
<div class="flow" style="width:150px;height:60px;">
<ul >
<li><img src="__PUBLIC__/images/demo/01.jpg" mce_src="__PUBLIC__/images/demo/01.jpg" width="150px" height="60px"></li>
