用html+jquery实现类似flash的地图区域选择效果

本效果仅使用了html热点和jquery，先上效果图：
鼠标悬停的区域变色
当鼠标悬停在不同的区域上时，被鼠标选中的市区会变成红色，下方可以显示相关的信息，支持点击事件。

以下是作法：
基本原理就是html的< map >标签可以在一张图片上定义不同的选区。选区的形状可以是矩形、圆形、多边形等：

<img id="shan_dong_pic" src="image/shandong.png" usemap="#area-map"/><map name="area-map" id="area-map">    <area shape="poly" coords="483,109,486,117" href="#">    </map>

这种方法也就是图片上的热点。
但是绘制多边形没有工具还是比较痛苦的，所以最好是把图片嵌入网页以后再用工具来描绘coords。我使用的是Dreamwear。像下面这样把每个区域的轮廓都画出来：这里写图片描述
这样一来整张图的不同区域就是可区分的了。
但是有个变色的问题。< area >是没有color或者background-color这样的属性的。所以鼠标悬停变色效果必须借助于其它的方法。
那就是颜色的变化只能借助图片的变换来实现。
于是，除了一张全部蓝色的山东地图。还有17张不同区域变色的图（选中区域为红色）。写一个js脚本实现当鼠标在某个area上悬停的时候把地图的图片换一下。
为了方便可以给area添加一些自定义的属性，使得能与不同区域图片的名称相对应。例如，全是蓝色的图片叫shandong.png，济南是红色的图片教shandong-jinan.png然后在济南区域的area里面添加自定义属性 zh-name=”济南” name=”jinan”像这样：

<area zh-name="济南" name="jinan" shape="poly" coords="xxx,xxx,..." />

然后在页面上加入js代码（需要jquery支持）：

<script type="text/javascript" >$(document).ready(function(){    /**鼠标进入某个区域触发事件***/    $("area").mouseenter(function(){        /****改变显示的图片****/        $("#shan_dong_pic").attr("src","image/shandong-"+$(this).attr("name")+".png");        /****在图片下方显示选择的市区****/        $("#region-name-show").html($(this).attr("zh-name"));    });});</script>

齐活了~
