javascript minus sign in variable

Question

I've got an XML-file. After converting it to JSON I want to access some content within. This was possible. However, some variable within the JSON contain a - (minus sign). When I try to access it, Javascript interpret this as a calculation. Is the only way to workaround this to replace all the - signs?

JSON **cannot** contain variables. Valid JSON is always single object or array — hindmost, Apr 09 '16 at 19:44

You can use brackets notation:

yourJson['ab-cd']; // access to 'ab-cd' property that contains '-' sign

If you want to define or access properties with special characters in them, you need to use string property names:

var obj = {
  'some-string-with-hyphens': true,
  'another-one': true
};

var another = obj['another-one'];
