要获取某个区域的 href 属性的查询字符串，请使用 search 属性。您可以尝试运行以下代码来搜索查询字符串 -
<!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").search;
document.write("<br>Querystring: "+x);
</script>
</body>
</html>
