My JSON: json_filter = {CO: blah} I am trying to access the member ‘CO’

  • 0

My JSON:

json_filter = {"CO": "blah"}

I am trying to access the member ‘CO’ by a string value. However, the result is undefined.

var selectedState = $(this).val();
// Selected 'CO'
console.log(json_filter.selectedState);

I was thinking eval() might work, but eval() == the devil 🙂 Is there a better way to do this?
