echarts geocoord如何Ajax动态获取数据库数据问题

求高手解答！谢谢

json标准必须使用双引号，改成双引号就可以了

现在tnsnames.ora 中的配置是这样的：
SYSIT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.12)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sysit)
)
)

ISYSIT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.12)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sysit)
)
)

用js遍历处理得到的json数据
