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：
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"
}]
}
