今天把公司的ERP项目中引入百度地图的任务搞定了，感觉很开心。希望再接再厉吧。fight.
不多说，先贴代码

<script  type="text/javascript">        $('#location').on('click',function(){            layer.open({//调用layer弹出层                 type: 2,                title: '地图位置',                scrollbar: false,                maxmin: false,                shadeClose: false, //点击遮罩关闭层                area : ['1000px' , '500px'],                content: '${ctx}/office.action?method:getLocation'            });        });    </script>

通过调用layer弹出框到’${ctx}/office.action?method:getLocation’即执行OfficeAction下的getLocation方法，通过getLocation的返回值映射到对应的jsp文件。显示出视图

效果为，可以生成一个自定义的标注，并且可以拖动标注，在拖动的同时，会自动生成对应的经纬度。这个不错，对于需要精确定位的比较有用。
