使用方法

在页面中引入jquery。

<script src="path/to/jquery.min.js" type="text/javascript"></script>

该焦点图的HTML结构如下：

<div class="focus">
    <div class="focusbox">         
        <div class="focusimg">
        <ul class="fimglist clearfix">

JavaScript

在页面DOM元素加载完毕之后，通过下面的jquery代码来初始化该焦点图插件。

jQuery(document).ready(function($){
$(".guidelist li").hover(
  function () {
    $(this).attr("class", "mouseon");
    },
    function () {
    $(this).attr("class", "mouseout");
    }
);
$(".ftoollist li").mouseover(function(){
  $(this).siblings().removeClass("on");
  $(this).addClass("on");
  var preNumber=$(this).prevAll().size();
  $(".fimglist li").removeClass("onpre");
  $(".fimglist li:nth-child("+preNumber+")").addClass("onpre");
  var margin = 990;
  margin = margin *preNumber; 
  margin = margin * -1;
  $(".fimglist").stop().animate({marginLeft: margin + "px"}, {duration: 500});
});
});
