html的img标签:定义一个图像在网页中引入。它还有个usemap属性很有意思。 看看51ditu首页中有一个地图,中部有个中国地图。点击右键下载下来看下就是一个普通的图片。 但点击地图上的省份却可以出发不同的事件(或打开不同的链接),很有意思。原来是使用了usemap属性。 当然还要定义一个map标签。整份代码如下: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gbk"> <title>img usemap属性</title> </head> <body> <img src="http://img.jb51.net/maps/chinamap.gif" usemap="#Map" border="1"/> <map name="Map" class="maparea"> <area shape="rect" coords="73,87,103,104" href="javascript:alert(新疆)"> <area shape="rect" coords="144,125,173,142" href="javascript:alert(青海)"> <area shape="rect" coords="84,158,115,175" href="javascript:alert(西藏)"> <area shape="rect" coords="220,90,257,105" href="javascript:alert(内蒙古)"> <area shape="rect" coords="348,45,389,61" href="javascript:alert(黑龙江)"> <area shape="rect" coords="346,68,371,83" href="javascript:alert(吉林)"> <area shape="rect" coords="323,84,351,100" href="javascript:alert(辽宁)"> <area shape="rect" coords="298,100,326,114" href="javascript:alert(天津)"> <area shape="rect" coords="288,120,314,136" href="javascript:alert(山东)"> <area shape="rect" coords="268,107,295,121" href="javascript:alert(河北)"> <area shape="rect" coords="207,116,235,130" href="javascript:alert(宁夏)"> <area shape="rect" coords="186,162,214,179" href="javascript:alert(四川)"> <area shape="rect" coords="256,142,281,157" href="javascript:alert(河南)"> <area shape="rect" coords="305,144,332,159" href="javascript:alert(江苏)"> <area shape="rect" coords="320,162,342,177" href="javascript:alert(上海)"> <area shape="rect" coords="216,168,243,185" href="javascript:alert(重庆)"> <area shape="rect" coords="250,162,277,177" href="javascript:alert(湖北)"> <area shape="rect" coords="283,161,308,177" href="javascript:alert(安徽)"> <area shape="rect" coords="213,196,239,209" href="javascript:alert(贵州)"> <area shape="rect" coords="243,183,269,198" href="javascript:alert(湖南)"> <area shape="rect" coords="273,185,299,200" href="javascript:alert(江西)"> <area shape="rect" coords="308,177,334,193" href="javascript:alert(浙江)"> <area shape="rect" coords="179,210,204,225" href="javascript:alert(云南)"> <area shape="rect" coords="227,214,252,228" href="javascript:alert(广西)"> <area shape="rect" coords="231,248,257,263" href="javascript:alert(海南)"> <area shape="rect" coords="292,200,319,214" href="javascript:alert(福建)"> <area shape="rect" coords="259,219,287,231" href="javascript:alert(广东)"> <area shape="rect" coords="244,231,270,246" href="javascript:alert(澳门)"> <area shape="rect" coords="276,232,304,248" href="javascript:alert(香港)"> <area shape="rect" coords="311,228,338,243" href="javascript:alert(台湾)"> <area shape="rect" coords="272,90,302,107" href="javascript:alert(北京)"> <area shape="rect" coords="196,130,222,145" href="javascript:alert(甘肃)"> <area shape="rect" coords="246,116,272,130" href="javascript:alert(山西)"> <area shape="rect" coords="224,136,252,151" href="javascript:alert(陕西)"> </map> </body> </html> 提示:您可以先修改部分代码再运行map标签里的area标签的几个属性意义见:http://www.w3school.com.cn/tags/tag_area.asp 这里还是记下area的shape属性,可选项有矩形,圆形和多边形。尤其要注意的是coords属性,得结合shape使用,图像左上角的坐标是 "0,0"。
