<area> 元素的 hreflang 属性用于设置区域中 URL 的语言。语法如下:−

<area hreflang="language_code">

上面的 code 是该语言的 ISO 语言代码集，例如，en 代表英语，fr 代表法语，js 代表日语等。

现在让我们看一个为 <area> 元素实现 hreflang 属性的示例 −

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" download="perl" hreflang="en"/>
   <area shape = "rect" coords = "22,83,126,125" alt = "HTML Tutorial"
      href = "/html/index.htm" target = "_blank" download="html" hreflang="en"/>
   <area shape = "circle" coords = "73,168,32" alt = "PHP Tutorial"
      href = "/php/index.htm" target = "_blank" download="php" hreflang="en"/>
</map>
</body>
</html>

输出

在上面的例子中，我们在下图中设置了地图 −

<img src = /images/usemap.gif alt = "usemap" border = "0" usemap = "#tutorials"/>

现在，我们已经为形状设置了地图及其内部区域 −

<map name = "tutorials">
   <area shape = "poly" coords = "74,0,113,29,98,72,52,72,38,27"
      href = "/perl/index.htm" alt = "Perl Tutorial" download="perl" hreflang="en"/>
   <area shape = "rect" coords = "22,83,126,125" alt = "HTML Tutorial"
      href = "/html/index.htm" target = "_blank" download="html" hreflang="en"/>
   <area shape = "circle" coords = "73,168,32" alt = "PHP Tutorial"
      href = "/php/index.htm" target = "_blank" download="php" hreflang="en"/>
</map>

我们使用 hreflang 属性来设置 URL 的语言 −
