Json in html

Question

(This may be a dumb question)

I am using a RESTful API to get data out of a database such as firstname, lastname etc. The API gives me the data in JSON and I want to use some of it in a webpage.

For example, I want to print

Welcome firstname lastname.

using the data from the JSON string.

How do I do this?

Answer 1

JSON is object notation. Whatever language you're using, you should be able to find a JSON library that can convert back and forth between a string and the object.

If you're using JavaScript, this code should work. The description for usage is here.

Answer 2

Assuming "myJSONtext" is well formed JSON, you can get an object representing the data with an eval:

var myObject = eval('(' + myJSONtext + ')')
