要获取图像的 usemap 属性值,请使用 useMap 属性。您可以尝试运行以下代码来显示 usemap 属性值 -
<!DOCTYPE html> <html> <body> <img id = "myid" src = "/images/html.gif" alt = "HTML Map" usemap = "#html"/> <map name = "html"> <area id = "myarea" shape = "circle" coords = "154,150,59" href = "about.htm" alt = "Team" > </map> <script> var x = document.getElementById("myid").useMap; document.write("<br>Usemap: "+x); </script> </body> </html>
