HTMLtarget 属性
<area> 元素的 target 属性可用于设置链接文档打开的位置,如新窗口、同一帧、父帧等。
语法如下:
<area target="_blank|_self|_parent|_top| frame">
此处, _blank 用于在新窗口或选项卡中打开链接文档,_self 在点击该链接时在同一帧中打开链接文档,_parent 在父帧中打开文档,_top 在整个窗口主体中打开链接文档,frame 在指定的帧中打开链接文档。
我们现在来看一个示例,演示如何实现 <area> 元素的 target 属性−
示例
<!DOCTYPE html> <html> <body> <h2>Learning</h2> <p>Learn these technologies with ease....</p> <img src = /images/usemap.gif alt = "usemap" border = "0" usemap = "#tutorials"/> <map name = "tutorials"> <area shape = "poly" coords = "74,0,113,29,98,72,52,72,38,27" href = "/perl/index.htm" alt = "Perl Tutorial" target = "_blank"/> <area shape = "rect" coords = "22,83,126,125" alt = "HTML Tutorial" href = "/html/index.htm" target = "_blank" /> <area shape = "circle" coords = "73,168,32" alt = "PHP Tutorial" href = "/php/index.htm" target = "_blank" /> </map> </body> </html>
输出
在以上示例中,我们已设置了下图的映射−
<img src = /images/usemap.gif alt = "usemap" border = "0" usemap = "#tutorials"/>
现在,我们设置了该图及其中的区域以实现形状−
<map name = "tutorials"> <area shape = "poly" coords = "74,0,113,29,98,72,52,72,38,27" href = "/perl/index.htm" alt = "Perl Tutorial" target = "_blank"/> <area shape = "rect" coords = "22,83,126,125" alt = "HTML Tutorial" href = "/html/index.htm" target = "_blank" /> <area shape = "circle" coords = "73,168,32" alt = "PHP Tutorial" href = "/php/index.htm" target = "_blank" /> </map>
上面,我们已将以下内容设置为在新窗口(即 _blank)中打开链接文档,该窗口或选项卡用于在新窗口或选项卡中打开链接文档
target = "_blank"
