JSON parsing escaped string

Question

Why dosen't JSON.parse parse this:

{
    "things1": "[{\"stuff1\":\"data1\"}]"
}

When I enter this

JSON.parse('{ "things1": "[{\"stuff1\":\"data1\"}]" }')

I get:

Uncaught SyntaxError: Unexpected token s

It seems "[{\"stuff1\":\"data1\"}]" is properly escaped.

Well, it's not a valid json. things1 attribute points to a string that starts with [{ and interrupts then. Where did you get it from? — zerkms

You are having escaping issues, specifically because you have nested strings. You need to double escape the \" bits using \\".

Edited: Meant to add a sample.

JSON.parse('{ "things1": "[{\\"stuff1\\":\\"data1\\"}]" }');
