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);
