难道<map>不支持appendChild方法？高手帮解决一下？

Question

document.getElementsById("map").appendChild(objArea);
==>objMap.appendChild(objArea);

Answer 1

问题出在document.getElementById多了一个s

Answer 2

我这里没有你定义的变量的值，所以暂且把你的变量名都改成字符串测试，下面代码是可以执行的，你看看<div id="ContentImage">
&nbsp;
</div>
<script language=javascript>
var objMap = document.createElement("map");
objMap.setAttribute("name","map");
objMap.setAttribute("id","map");
document.getElementById("ContentImage").appendChild(objMap);alert(document.getElementById("ContentImage").innerHTML)
objArea = document.createElement("Area");
objArea.setAttribute("id","strID");
objArea.setAttribute("name","strName");
objArea.setAttribute("coords","strcoords");
objArea.setAttribute("shape","strShape");
objArea.setAttribute("href","strHref");
document.getElementById("map").appendChild(objArea);
alert(document.getElementById("ContentImage").innerHTML)
</script>
