Generation of navigation elements, etc. from JSON?

Question

PHP

There is a web service written in Java that sends everything to json for almost all navigation elements (not counting the content itself), after which this stream needs to be collected and put in its place according to the template.
Tell me how it's done? What should you pay attention to and where to start?

Answer 1

There is a function JSON.parse(); Let's say data comes in, you create a variable var x = JSON.parse(data); then you work with the x variable as with a regular js object - x.name, x.age and so on.
