Construct a JSON Payload in javascript

[Nitesh Balusu]

Hello!

I have to construct a JSON payload that looks like this, can someone help me? I am able to get the straight forward one but unable to build a nested payload. How do I go about adding more nested keys, one inside the other. Also some of the keys and values are dynamic and have to replaced with variables.

This link helps a little but unable to understand how to build keys one within another.

The easiest way to build JSON is to first build a JavaScript object. It appears that you already have a JSON object. Then just call JSON.stringify;

var json = JSON.stringify(obj);

You just need to make sure that your object does not contain any GlideRecords or GlideElements. Only strings, numbers, arrays and other nested objects (as in your example).

My requirement is, a user fills in a catalog form and on submission I need to take values from the variables the user filled and create a JSON file that looks like the one I posted in the question. I do not have a JSON object I believe, have to pull values from the variables and build it.

Did you try it?  JSON is available as a javascript object both server and client side.

Like Giles said, just build an object and stringify it.

var obj = {};

obj.prop1 = {};

obj.prop2 = "Test";

obj.prop1.subprop = {};

and so on

Can you share the script that you tried?
