问题描述

我是Raphael的新手，无法从现有元素创建Raphael对象。
下面的代码显示了我尝试过的内容以及每个人造成的错误。理想情况下，我想在首次调用Raphael时使用jquery创建对象。
任何帮助将非常感激。

<body>
<form id=\"form1\" runat=\"server\">
<img class=\"mapClass\" id=\"imgMap\" name=\"imgMapName\" style=\"position: absolute\" src=\"Images/map.gif\"
alt=\"\" />
</form>
解决方法
尝试这个：
var thisDoeNotWorkA = Raphael(\'imgMap\',200,200);
