热区Map Area用法
Map标签
map热区需要配合img标签使用,只有img标签有usemap属性。
usemap指定某个id的map,map标签内指定多个area,area需要指定形状和坐标,跳转的url,也可以指定onclick、onmousemove等事件。
<img src="planets.jpg" border="0" usemap="#planetmap" alt="Planets" /> <map name="planetmap" id="planetmap"> <area shape="circle" coords="180,139,14" href ="venus.html" onfocus="blur(this);" alt="Venus" /> <area shape="rect" coords="0,0,110,260" href ="sun.html" onfocus="blur(this);" alt="Sun" /> </map>
