通过idesktop制作的两个图层，如下所示：
这个两个图层发布到iserver上能够单独显示，但是通过iserver进行图层覆盖之后，只能显示单一图层
代码如下：
<!DOCTYPE>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>twoMap</title>
<style type="text/css">
/* body{ */
/* margin: 0; */
/* overflow: hidden; */
/* background: #fff; */
/* } */
/* #map{ */
/* position: relative; */
/* height: 520px; */
/* border:1px solid #3473b7; */
/* } */
/* #toolbar { */
/* position: relative; */
/* height: 33px; */
/* padding-top: 5px; */
/* } */
</style>
