这是一款使用jquery和png图片来制作的中国省份地图特效插件。该中国省份地图插件使用多张png图片来组成中国省份地图，并在鼠标滑过各个省份时将其高亮。

使用方法

在页面中引入jquery和样式文件style.css。

<link rel="stylesheet" type="text/css" href="css/style.css" />
<script type="text/jscript" src="js/jquery.min.js"></script>
HTML结构

该中国省份地图使用<div>配合png图片来制作，完整的代码如下：

初始化插件

在页面DOM元素加载完毕之后，通过下面的方法来使鼠标滑过相应的省份时将其高亮。

$(document).ready(function(){
  maphover();
});

function maphover(){
  var self = "";
  $(".city").hover(
    function(){
      self = $(this);
      self.addClass("hover").children("div").show();
    },
    function(){
      self = $(this);
      self.children("div").hide();
      self.removeClass("hover");
    }
  );
  $(".city").click(
    function(){
      self = $(this);
      self.addClass("hover").children("div").show();
    },
    function(){
      self = $(this);
      self.children("div").hide();
      self.removeClass("hover");
    }
  );
    
};
