(Node.js) JSON: Array of ObjectsHere we have a JSON object that contains an array, where each element in the array is a JSON object. This example demonstrates how to access the objects contained within an array. { "employees":[ {"firstName":"John", "lastName":"Doe"}, {"firstName":"Anna", "lastName":"Smith"}, {"firstName":"Peter","lastName":"Jones"} ] }
var os = require('os'); if (os.platform() == 'win32') { var chilkat = require('@chilkat/ck-node23-win64'); } else if (os.platform() == 'linux') { if (os.arch() == 'arm') { var chilkat = require('@chilkat/ck-node23-linux-arm'); } else if (os.arch() == 'arm64') { var chilkat = require('@chilkat/ck-node23-linux-arm64'); } else { var chilkat = require('@chilkat/ck-node23-linux-x64'); } } else if (os.platform() == 'darwin') { var chilkat = require('@chilkat/ck-node23-mac-universal'); } function chilkatExample() { var json = new chilkat.JsonObject(); // This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars). // The presence of whitespace chars for pretty-printing makes no difference to the Load // method. var jsonStr = "{\"employees\":[{\"firstName\":\"John\", \"lastName\":\"Doe\"},{\"firstName\":\"Anna\", \"lastName\":\"Smith\"},{\"firstName\":\"Peter\",\"lastName\":\"Jones\"}]}"; var success = json.Load(jsonStr); if (success !== true) { console.log(json.LastErrorText); return; } // Get the "employees" array. // employees: JsonArray var employees = json.ArrayOf("employees"); if (json.LastMethodSuccess == false) { console.log("employees member not found."); return; } // Iterate over each employee, getting the JSON object at each index. var numEmployees = employees.Size; var i = 0; while (i < numEmployees) { // empObj: JsonObject var empObj = employees.ObjectAt(i); console.log("employee[" + i + "] = " + empObj.StringOf("firstName") + " " + empObj.StringOf("lastName")); i = i+1; } } chilkatExample(); |
