Angular - fetch the value from JSON object based on condition
Asked on May 08, 2019
Hi,
I want to fetch the value from JSON object based on condition .
For Example :
I have following JSON Object.
{"text": "India","value": 1,"locationCode": "001","children": [{"text": "Karnataka","value": 37,"locationCode": "EX01","disabled": "false","children": [{"text": "Hubli","value": 38,"disabled": "false","locationCode": "UBL01","children": [{"text": "Vidyanagar","value": 43,"disabled": "false","locationCode": "VID01","children": []}]},{"text": "Bangalore","value": 40,"disabled": "false","locationCode": "BANG01","children": [{"text": "JayNagar","value": 48,"disabled": "false","locationCode": "JAY000","children": [{"text": "Vidyagiri","value": 56,"disabled": "false","locationCode": "VID001","children": []}]}]},{"text": "Mysore","value": 57,"disabled": "false","locationCode": "CG002","children": []}]}]}
From this JSON I want to pass one location name and fetch the parent (grand parents)and children
(grand children) of the passed location.
For Example: If I pass Banglore location , then I should get following JSON response:
{"text": "India","value": 1,"locationCode": "001","children": [{"text": "Karnataka","value": 37,"locationCode": "EX01","disabled": "false","children": [{"text": "Bangalore","value": 40,"disabled": "false","locationCode": "BANG01","children": [{"text": "JayNagar","value": 48,"disabled": "false","locationCode": "JAY000","children": [{"text": "Vidyagiri","value": 56,"disabled": "false","locationCode": "VID001","children": []}]}]}]}]}As response It should give parents(grand parents) and children (grand children) of Bangalore location.How to achieve this?Can any one please provide solution for this?Thanks & Regards,Shilpa Kulkarni

Any specific reason to filter JSON tree in such format?
We can use JSON.parse() to get JSON Object, JSON Array etc and iterating JSON, we can get required data.
