HTML map标签图片区域链接

在Html中，给图像使用map标签，可以给图像的某个部分建立超连接，用法如下： 

  1. <img src=img.gif usemap="MAP-Name">  
  2. <map name="MAP-Name">  
  3. <area shape="rect|circle|poly" coords="#" href="url">  
  4. </map>  

注:所有的坐标都是相对于图片左上角的 

其中，坐标coords对各个shape的解释如下： 

 
  1. shape="rect" coords="x1,y1,x2,y2" // (x1,y1)=Upper Left, (x2,y2)=Lower Right   



即，当shape是矩形时，coords表示矩形左上及右下(x2, y2)的坐标 

引用
shape="circle" coords="x,y,r" // (x,y)=Center, r=Radius



即，当shape是圆形时，coords表示圆中心点坐标(x, y)及半径 

  1. shape="poly" coords="x1,y1,x2,y2,x3,y3..." // (x1,y1>=First Corner, (x2,y2)=Second Corner, ...  



即，当shape是poly多边形时，coords表示多边形所有顶点的坐标(x1,y1),(x2,y2),(x3,y3)... 


注意：以上所有坐标都是相对于图形img.gif左上脚坐标而言的 


以下是一个例子: 

 
  1. <img src="mapimg.gif" usemap="#Face">  
  2. <map name="Face">  
  3.    <area shape="rect" href="page.html" coords="140,20,280,60">  
  4.    <area shape="poly" href="image.html" coords="100,100,180,80,200,140">  
  5.    <area shape="circle" href="new.html" coords="80,100,60">  
  6. </map>

    3.   <div align="center"><img src="city_map.gif" width="740" height="595" border="0" usemap="#Map">
