key values

The basis for accessing key values is the JSON string of the business$keyValuesis available: 

For the conversion, all ' are replaced by " .

var keys = JSON.parse(business$keyValues.replace(/'/g, '"'));; // JSON ARRAY all key values

Then you read the key values line by line:

for(var i = 0; i< keys.length; i++) {

   var key = keys[i];  // JSON OBJECT a key

   var keyAlias = key['alias'];

   var keyValue = key['value'];

}
