12）函数指针
例 3.12.1

<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<script type="text/javascript">
function sortNumber(a, b)
{
document.writeln(a + b);
}
function sortq(sortNumberqqq)
{
document.writeln("马克-to-win");
sortNumberqqq(1, 2);
return 6;
}
/* note that it will report error if we write the following statement as document.write("test "+sortq(sortNumberqixy));
note that here sortNumber is a function pointer.
下面这句话是先执行sortq(sortNumber)，等返回值以后，再执行document.write("test "*/
document.write("test " + sortq(sortNumber));
