do we have any javascript / nodejs plug-ins to pick a given property?

Question

Sachin Singh · Answer

there is a simple rule of thumb. 1. you can not get JSON value directly, so convert it into a javascript object, using Json.parse(); 2. Javascript objects are accessed by dot (.) 3. Arrays are accessed by index ex:- array[1]. now apply that. const txt = `{ "prop1": "John Doe", "prop2": 35, "prop3": { "prop4": { "prop5": "Susan", "prop6": 32 }, "prop7": [ { "prop8": "Alex", "prop9": 5, "prop10": "dancing" } ] }, "prop11": [ { "prop12": "BMW X5", "prop13": 2015 }, { "prop14": "Tesla Model S", "prop15": 2018 } ] }` const obj = JSON.parse(txt); var prop8Value = obj.prop3.prop7[0].prop8 ; // Alex

Hi, You can in this way: var data = { "prop1" : "John Doe" , "prop2" : 35, "prop3" : { "prop4" : { "prop5" : "Susan" , "prop6" : 32 }, "prop7" : [ { "prop8" : "Alex" , "prop9" : 5, "prop10" : "dancing" } ] }, "prop11" : [ { "prop12" : "BMW X5" , "prop13" : 2015 }, { "prop14" : "Tesla Model S" , "prop15" : 2018 } ] }; var jsonGetData = JSON.parse(data); var prop8Value = jsonGetData.prop3.prop7[0].prop8; /// this will give value of prop8

Hi, You can parse into json ad get property example: var data = { "name" : "" , "skills" : "" , "jobtitel" : "Entwickler" , "res_linkedin" : "GwebSearch" } var parsedData = JSON.parse(data); alert(parsedData.name); alert(parsedData.skills); alert(parsedData.jobtitel); alert(parsedData.res_linkedin);
