How To Solve Uncaught SyntaxError: Unexpected token o in JSON at position 1 Error ?

Solution 1

Let me Explain Why you are facing this error Here are the first parameters of the function JSON.parse should be a String, and your data is a JavaScript object, so it will convert to a String [object object], you should use JSON.stringify before passing the data. Here is Some Example.

new Object().toString()
// "[object Object]"

JSON.parse(new Object())
// Error: Uncaught SyntaxError: Unexpected token o in JSON at position 1

JSON.parse("[object Object]")
// Error: Uncaught SyntaxError: Unexpected token o in JSON at position 1

JSON.parse(JSON.stringify(userData))
// This Will Work

So Here You should Use

JSON.parse(JSON.stringify(userData))

Solution 2

Here JSON.parse() converts the input into a string. The toString() method of JavaScript objects by default returns [object Object], resulting in the observed behavior. So that you just need to use this.

var newData = userData.data.userList;
