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>
