要在JavaScript中搜索图像映射区域的替代文本(alt),请使用 alt 属性。您可以尝试运行以下代码以获取替代文本。

示例

<!DOCTYPE html><html>   <body>      <img src = "/images/html.gif" alt = "HTML Map" border = "0" usemap = "#html"/>           <map name = "html">         <area id = "myarea" shape = "circle" coords = "154,150,59" href = "about.htm?id=company" alt = "Team" target = "_self" >      </map>      <script>         var x = document.getElementById("myarea").alt;         document.write("<br>Alternate Text: "+x);      </script>   </body></html>
