Assign json stored in a file to a js variable

Question

I am working on a project and I was not able to figure out how to do this. I have a json file and need to assign it to a js variable to use the protovis visualization tools.

I tried searching on google but could not find any. Please let me know if someone knew how to do this. Thanks!

Answer 1

Use jQuery's parseJSON().

Answer 2

If you're getting the file from your server via the XMLHttpRequest object, you can parse the json using the JSON.parse function:

var myJson = JSON.parse(response);

For browsers that don't support the JSON object you can get a library for it here: http://www.json.org/js.html
