JQuery to access the data of the data in the JSON file

This example tells the method of jQuery access to data in the JSON file. Share to everyone for your reference, as follows:

Sometimes we may need to use JSON file storage data and then directly accessed through the front desk language.

First is JSON file:

{“Pipe”: [{“ElementID”: “Identification Number”, “Gisid”: “gisid”, “Label”: “No.”, “StartNodeID”: “Start Node ID”, “EndNodeID”: “Termination Node ID”, “StartNodeLabel”: “Start Node Number”, “EndNodeLabel”: “Termination Node”, “Physical_PipeDiameter”: “diameter”, “Physical_PipeMaterialID”: “pipe”, “Physical_HazenWilliamsC”: “Hazen William value C”, “Physical_Length”: “pipe length”, “Physical_MinorLossCoefficient”: “local resistance coefficient”, “Physical_InstallationYear “:” PHYSICAL_ADDRESS “:” Address “,” DISTRICT “:” Marketing Company “,” DMA “:” Measurement Zone “,” Zone “:” Administrative Region “,” Flow “:” Current Traffic “, “Velocity”: “Current Flow Period”, “Headloss”: “Current water loss”}], “node”: [{“elementid”: “identification number”, “gisid”: “gisid”, “label”: “Number “,” Physical_Elevation “:” Ground elevation “,” Physical_DEPTH “:” Bede “,” Physical_address “:” Address “,” DISTRICT “: Marketing Company,” DMA “:” Measurement Zone “,” Zone “:” Administrative District “,” Hydraulicgrade “:” Hydraulic “,” Pressure “:” Free Water Pressure “,” Demand “:” Node Traffic “,” CL “:” Residual Chlorine Concends “,” AGE “:” Shui Ape “,” Source “:” Water supply “}] , “Valve”: [{“ElementID”: “Identification”, “Gisid”: “Gisid”, “Label”: “Physical_Elevation”: “GISICAL_ELEVATION”: “Physical_Depth”: “buried”, “Physical_Diameter”: “Physical_status”: “Valve State”, “Physical_address”: “Address”, “DISTRICT”: Marketing Company, “DMA”: “Measurement Zone”, “Zone”: “Administrative Region” “Physical_InstallationYear”: “The installation age”}], “water meter”: [{“Diameter”: “Caliber”: “Caliber”, “Material”: “Material”, “depth”: “buried deep “,” Height “:” Ground Elevation “,” Addr “:” Addr “:” Table Number “,” UserName “:” User Name “,” Junction “:” Interface Type “,” District “: “Administrative Region”, “Measurein”: “Marketing Company”, “FinishDate”: “Installation Date”}], “Fire Hydr”: [{“ElementID”: “Identification Number”, “Gisid”:”Gisid”, “Label”: “No.”, “Physical_Elevation”: “Physical_Depth”: “Bede”, “Physical_address”: “Address”, “Marketing Company”, “DMA” : “Measurement Zone”, “ZONE”: “Administrative Region”, “Physical_Diameter”: “Call”, “Physical_Type”: “}]}
Create criteriaQuery. JSON file, the file content is as above.

jQuery Access JSON
   $ ("# btn"). Click ("criteriaQuery.json", Function (DATA) {var $ jsontip = $ ("# jsontip"); Var strHtml = ""; $ jsontip.empty (); $ .each (data) {strHtml + = info [o];} // strHtml + = INFO [ "ElementID"];}); $ jsontip.hTML (strHtml);}})})           
I have a 1.4.0 version of JS file here, https://libs.baidu.com/jQuery/1.4.0/jQuery.min.js
JSON file is placed in the same directory with HTML.
Run the code, click to get the data button, you can see all the information of the "pipe" obtained by traversing the JSON file on the page. Of course, you can also get the value of the JSON file by Key, ie
strHTML + = INFO [“ElementID”];
