<esri:Map >

        <esri:extent>

            <esri:Extent xmin="313983.806152495" ymin="243957.685897649" xmax="703990.033700897" ymax="441506.532227649">

发布的图形服务包含的信息:

空间参考,初始的extent,全图的extent

myMap.extent.xmin.toFixed(0)

scaleBarVisible:比例工具栏是否可见

zoomSliderVisible:放缩工具栏是否可见

LODS数组可以指定放缩工具栏.
