removing quotation marks from responsetext property

Question

I am trying to remove quotation marks from the responseText property of a XMLHttpRequest object.

My output is :

"[{"data":[[0,28]],"label":"Atyc-1"},{"data":[[0,13]],"label":"Atyc-10"},{"data":[[0,16]],"label":"Atyc-11"},{"data":[[0,17]],"label":"Atyc-2"},{"data":[[0,5]],"label":"Atyc-3"}]"

what I need is:

[{"data":[[0,28]],"label":"Atyc-1"},{"data":[[0,13]],"label":"Atyc-10"},{"data":[[0,16]],"label":"Atyc-11"},{"data":[[0,17]],"label":"Atyc-2"},{"data":[[0,5]],"label":"Atyc-3"}]

Answer 1

Try this:

JSON.parse(xhr.responseText);

Explanation:

It's a JSON response, which means the server is responding with JSON format. In order to use it properly in JavaScript, you need to parse the string as JSON using the JSON.parse() function. That will convert the JSON object to the response you need.

Answer 2

responsetext.substring(1, responsetext.length - 1);

This will return the string with the first and last characters removed.
