jQuery访问json文件中数据的方法示例-创新互联
本文实例讲述了jQuery访问json文件中数据的方法。分享给大家供大家参考,具体如下:
从事重庆服务器托管,服务器租用,云主机,虚拟主机,域名注册,CDN,网络代维等服务。有时候我们可能需要用到json文件存储数据,然后通过前台语言直接进行访问。
首先是json文件:
{ "管道": [ { "ElementId": "标识号", "GISID": "GISID", "Label": "编号", "StartNodeID":"起始节点ID", "EndNodeID":"终止节点ID", "StartNodeLabel":"起始节点编号", "EndNodeLabel":"终止节点编号", "Physical_PipeDiameter":"管径", "Physical_PipeMaterialID":"管材", "Physical_HazenWilliamsC":"海曾威廉C值", "Physical_Length":"管长", "Physical_MinorLossCoefficient":"局部阻力系数", "Physical_InstallationYear":"铺设年代", "Physical_Address":"地址", "District":"营销公司", "DMA":"计量区", "Zone":"行政区", "flow":"当前流量", "velocity":"当前流速", "headloss":"当前水头损失" }], "节点": [{ "ElementId": "标识号", "GISID": "GISID", "Label": "编号", "Physical_Elevation":"地面高程", "Physical_Depth":"埋深", "Physical_Address":"地址", "District":"营销公司", "DMA":"计量区", "Zone":"行政区", "hydraulicGrade":"水压标高", "pressure":"自由水压", "demand":"节点流量", "cl":"余氯浓度", "age":"水龄", "source":"供水水源" }], "阀门": [{ "ElementId": "标识号", "GISID": "GISID", "Label": "编号", "Physical_Elevation":"地面高程", "Physical_Depth":"埋深", "Physical_Diameter":"口径", "Physical_Status":"阀门状态", "Physical_Address":"地址", "District":"营销公司", "DMA":"计量区", "Zone":"行政区", "Physical_InstallationYear":"安装年代" }], "水表": [{ "DIAMETER":"口径", "CALIBER": "表径", "MATERIAL": "材质", "DEPTH":"埋深", "HEIGHT":"地面高程", "ADDR":"地址", "WATREGID": "表号", "USERNAME":"用户名", "JUNCTION":"接口类型", "DISTRICT":"行政区", "MEASUREIN":"营销公司", "FINISHDATE":"安装日期" }], "消火栓": [{ "ElementId": "标识号", "GISID": "GISID", "Label": "编号", "Physical_Elevation":"地面高程", "Physical_Depth":"埋深", "Physical_Address":"地址", "District":"营销公司", "DMA":"计量区", "Zone":"行政区", "Physical_Diameter":"口径", "Physical_Type":"样式" }] }
